Just after midnight on 20/04 it appears DSSD #4 leakage current has perfectly stabilised. See attached.

DSSDs remain biased.

20 April

19:30 - leakage current still stable but anydesk connection not working.

Machine is connected, but connection fails.

21 April

Anydesk connection works again. Leakage current remains stable. What changed?

D+D minimum energy Ecm = 150 keV which corresponds to Ed=150 keV/u or Ed=300 keV. Therefore we need a threshold below this.

Test 1 - Current status

Current slow comparator threshold is 0x64 (1 MeV). ADC data items rate in all FEEs is essentially zero with this threshold. (except aida03 and aida04). Aida15 and 16 also show ~1k rates when DSSD4 current is fluctuating.

Pulser was set to find point it is cut off by the threshold. Attachments 1,2,3 show 1.8L for nn channels with the pulser set to 570,550 and 530. Over this range pulser disappears. Estimate 550 is equal to ~1 MeV.

Test 2 - Noise level at lower threshold 200 keV

Threshold set to 0x14 (200 keV). Pulser kept at 550 for the time being to gauge location of noise compared to pulser. Attachments 4,5 show 1.8L for nn and pn channels respectively. Some noise observable at low energy.

Note zero energy is around 32500 channels. In nn channels (attachment 4) pulser is to the right of the noise peak, wheras in pn channels (attachment 5) pulser is to the left of noise peak.

Attachment 6 shows data rates with pulser off. Rates okay, only aida15 has very high rate (80k), rest of channels <5k.

Test 3 - Noise level at lower threshold 100 keV

Threshold set to 0xa (100 keV). Pulser kept at 550 for the time being. Attachment 7 shows data rates with pulser off. Rates significantly higher all round. Half of channels >50k, some >100k.

Attachments 8,9 show 1.8L for pn and nn channels respectively. A lot more noise observable at low energy. Pulser peaks generally overshadowed by noise. 100 keV probably too low to set threshold.

Test 4 - Noise level at lower threshold 150 keV

Threshold set to 0xf (150 keV). Pulser kept at 550 for the time being. Attachment 10 shows data rates with pulser off. In general rates are pretty low. Most channels <1k. Aida15 and 16 pretty high.

Attachments 11,12 show 1.8L for nn and pn channels respectively. Noise observable at low energy but in general less than that of the pulser peaks.

Test 5 - D+D pulser peak at lower threshold 150 keV

Theshold kept at 0xf (150 keV). Pulser set to 180 (should be about 300 keV based on Test 1). This should be the level of d+d at our lowest beam energy.

Attachments 13,14 show 1.8L for pn and nn channels respectively.

Test 6 - D+D pulser peak at lower threshold 200 keV

Theshold increased to 0x14 (200 keV). Pulser kept at 180 (should be about 300 keV based on Test 1). This should be the level of d+d at our lowest beam energy.

Attachments 15,16 show 1.8L for nn and pn channels respectively.

09:10

Arrived at GSI. Leakage currents status same as before, DSSD4 is still fluctuating. DSSD1 and DSSD3 currents are definitely lower again compared to previous days. I am convinced they are decreasing over time, whether this will be enough for our measurement....

While in the cave I again removed the motors pins so that the detectors can can be shook in an attempt to perform magic. While in the cave I also connected the CRYRING ground cable to the coolant pipe (ground config 11). Will see effect on rates / pulser.

Ground config 11 - see attachments 1-8. Rates in aida03 are massively down by a factor 10! Rates now ~20k. Aida04 still around 300k. On attachment 4 we can see the noise from zero energy on aida03 is massively down and we can now see the pulser, although the peak is double. Similar low energy noise is now appearing on aida15 and aida16 of DSSD4. Is this the early phase of what happended to DSSD1 and DSSD3?

Note the waveforms shown in attachments 7 and 8 change quite alot when updating the spectrum browser. Wave structure very visible in 7 but after updating a few times this disappears before coming back again a bit later.

20 minutes later ...

DAQ continued for about 20 minutes, noticed the leakage current in DSSD4 was no longer fluctuating. Zero'd stats and histograms to look again.

Stats in aida03 have increased back to ~100k, still less than before but back up from ~20k. Check of the pulser widths shows they have decreased across the board from the previous test 20 mins ago.

Leaving DAQ to run for a bit longer, the rates in aida03 continue to increase and are now back ~200k (back where it was).

I am currently trying to cycle motors. No effect on leakage current when cycling pneumatic motor. Note when using single commands such as 'l p in' I have no problems. But when trying a longer command where I ask the code to wait before pulling the pneumatic out again the code crashes. ??? Crash not repeated by Carlo remotely, Perhaps it is my laptop, or a bug relating to windows. Will investigate back in Edinburgh.

Have performed the same bias test for DDSD4 as #1 and #2 in previous elogs. Same behaviour observed. No (0.01uA) leakage current with only nn and current ramps up and falls to zero with only pn. I did notice that the ion pumps were arcing, I have not noticed this in prevous days. They have now been turned off, I think we can leave them off as they do little for the vacuum anyway unless using heavy gas taget gas. VI bias curve looks identical to one performed at the start of the week.

I have moved the PC power to the 19 inch rack. Power cycled the FEEs. I noticed the leakage current on DSSD4 was fine during VI test but after starting the FEEs power cycle they started to fluctuate again. After about 5 minutes after the startup, DSSD4 leakage current returned to a normal stable level. I have seen spikes in leakage current for all detectors during power cycle but perhaps it could also cause the fluctuations in #4. Overnight I have left FEEs off due to uncertainty over the swagelock on aida08 and the fact I was changing ground a lot so a background didn't make sense. Perhaps leaving FEE power on will stabilise DSSD4? I will leave system to stabilise a bit now (after seeing rates and pulser widths change in previosu test) and check pulser widths. Going for an awful GSI coffee.

New configuration: See attachments 9-13. Rates on aida03 and aida04 still remain very high >200k. Pulser widths across the board look pretty good. All have reduced since moving the PC on same power supply as 19 inch rack. DSSD4 leakage current has been stable the last hour since FEE power on. Waveforms look improved too. No longer see such high amplitude oscillations. Updated several times, see no change in waveforms like previous test.

Attachment 14 for pulser widrths from tests this week. Note x means no value. This could be because the width was so very big, or the test input wasn't connected. These values aren't too bad. DSSD2 and 3 have avergae pulser width (1.8L only) of ~60 keV.

Tried ground cable to NIM bin, had no effect / maybe negative effect. Disconnected cable.

D+D tests in next elog

Finally a pulser walkthrough was completed. Run8 has pulser settings unchanged, slow comparator at 0x64, aida03 and aida04 set to MEC. Pulser amplitudes 9000,8000,7000,6000,5000,4000,3000,2000,1000

A second walkthrough (Run9) was done with slow comparator set to 0x14, aida03 and aida04 set to MEC. Pulser amplitudes 9000,8000,7000,6000,5000,4000,3000,2000,1000,700,400 (so that we can check ~BBN energies) - attachment 15

During second walkthrough, DSSD4 starting fluctuating in leakage current again. No-one was in the ring. No observable change. FEEs were ON and were currently acquiring. ?? See noise which in attachment 15 on aida15/16 that only started when current was fluctuating.

FEEs off. Bias on and monitoring. Pins re-inserted into motors. Compressed air off.

09:00

Came in to see the bias for DSSD4 which has been fluctuating for the past few days had tripped during the night. From the gnuplot it looks like it was fluctuating all night and just after midnight it went above 20uA and tripped.

Other leakage currents are around the value they have been recently, day night cycle still observed. Again perhaps the leakage current of DSSD1 and DSSD3 is slowly decreasing and reaching a lower minimum value. Reset the module, DSSD4 does bias back up and is currently around 10uA. See attachments 1+2.

I have also noticed a small spike in current when starting up the FEE power, see the small spikes in attachment 2.

Continuing with different ground configurations from yesterday.

Ground config 5: I have now removed the grounding cables between non-bias FEE modules. So grounding cable goes between pn and nn bias FEEs and then one grounding cable to the coolant pipe. No grounding on any other FEEs. (attachments 3-8). Effect on pulser widths is hard to discern, some widths have decreased i.e 5 and 6 wheras others have increased such as 11. One interesting note is that the rates on aida03 have decreased by just over a factor 2 so now read ~100k. Whether this is the result of different grounding or maybe similar to what was seen for DSSD3 where rates decreased on there own over time? Attachment 8 shows the rates for each ASIC and most have now reached similar level to the other FEEs (note log scale).

Ground config 6: Have kept grounds to only pn or nn bias FEEs. Have now also included a ground cable from the body of the FEE module into the grounding connection. The ADC data items rate increase from 100k to 150k in aida03, no other impact on rates. Pulser widths remain largely unchanged, although some widths saw increases in the pulser widths. (attachments 9-13)

Ground config 7: Wanted to check impact of having no grounds at all. No impact on leakage currents. Rates look pretty similar for all FEEs, aida03 and aida04 200k and 350k respectively. Pulser widths and waveforms significantly worse than grounded case. See attachments 14-18

Ground config 8: Have reattached all ground cables (back to config1). In addition I have added a ground cable from the coolant pipe to effectively the CARME chamber. Rates appear pretty unchanged. Pulser widths better than no grounding but worse than original configuration. Attachments 19-23

Note since after lunch DSSD4 leakage current no longer fluctuating. Nothing has been changed. As I write that currents start fluctuating again. Maybe some ongoing work in the cave is affecting this?

Removed groud cable going to the chamber.

I wanted to rule out any affect from the test inputs. Have removed all test inputs. Only input is directly from pulser to DSSD3 as this previously had best pulser widths. All other cables removed. See attachments 24-26. Still see very high rates in aida03 and aida04 (250k and 350k). Pulser widths in DSSD3 seem worse now for some reason? While pulser detattched decided to lower slow comparator to 0x32 (500keV) and 0x24 (360 keV) to see rates in all FEEs. Rates still look pretty good, other than aida03 and 04. See attachments 27,29. Putting test inputs back.

Test inputs all back. Ground configuration back to configuration 1. Pulser tests, widths are best so far - will upload them later from all tests.Rates good in all except aida03 and aida04 still.

FEEs off, bias on and monitoring. Have put pins back in motors.

20:50

Bias has tripped again on DSSD4. It had remiained stable with noi fluctuations ~20 mins before leaving.

09:00

Leakage currents this morning again appear to have lowered during the night. Current plot shows a day/night variation but I think the minimum is decreasing ever so slightly.

This morning DSSD1=15.1uA and DSSD3=14.4uA, this is ~0.3-0.4 uA lower than yesterday. DSSD4 is still fluctuating in its leakage current and looks to have been all night. See attachment 1.

Will now proceed to systematically check all grounds before restarting AIDA.

Several cables have been re-routed this morning to clean up the area, allow us to see clear what cable goes where, and are avoid any unwanted interference. E.g. ion pump cables have been re-routed to not be near the bias cables, one ion pump cable was running between the power and hdmi on one of the FEEs, this was been sorted.

All grounds have been checked, some loose cables have been tightend up. Current ground configuration has all the adaptor cards (nn and pn) on a single detector connected together. One grounding cable then goes from each detector to the right coolant pipe which all the other detectors are also grounded to. This was the configuration for the previous beamtime. Will start pulser tests after lunch. Bias back on, leakage current slowly increasing again, DSSD3 current no longer fluctuating.

13:00

Ground config 1 - attachments 2-7 (described above)

Ground config 2 - attachments 8-10 (grounds now go to the CRYRING ground cable not the coolant pipe and jumper removed form bias module)

pulser widths 1.8L worse pretty much across the board. No sig impact on rates

Ground config 3 - attachments 11-14 (grounds returned to coolant pipe)

pulser widths 1.8L better than config 2 but still worse than config1

Ground configuration returned to first configuration. Pulser widths consistent with that seen before.

Additional bias tests.

Disconnected the pn bias cable (core) from DSSD1 but left nn bias cable connected. Biased. Observed bias ramp up but no leakage current was seen.

Reconnected pn bias cable but now disconnected nn bias cable. Biased. Observed bias ramp up, leakage current was seen to increase during ramp to ~8uA. Once fully ramped, leakage current started to slowly decrease and eventually went to zero.

Repeated same tests with DSSD2. Same behaviour observed as with DSSD1.

Have removed motors pins and tried some movement again. No effect on leakage current. Checked pulser widths before movement and after movement (with pnuematic IN). No change in pulser widths.

End of day status FEEs off, bias on and monitoring. Motor pins out to allow for last movement check, motors code running in screen session.

14/04/25

Arrived at GSI in the afternoon.

Found that the coolant loop on aida08 had popped out which resulted in the high FEE temperatures observed (see attachment 1). Female swagelock connector on FEE suggested to be the cause as this connector has the locking mechanism. FEE dismounted and female swagelock connector removed. No obvious defect in the connector (see attachment 2).

Turning on detectors we observe ~4uA in DSSD2 and DSSD4 (right hand side detectors) and ~15uA in DSSD1 and DSSD3 (left detectors). Leakage currents in left hand side detectors is down from ~17uA seen at the end of last week and ~19uA at start of last week. Temperatures in the cave do not appear to have changed sufficiently to explain this change. VI curve completed to test diode response (attachment 3+4).

Motors turned on to again see if it changes the leakage currents in any way. Both arms homed. Left arm moved in with pneumatic and servo (10mm). No change in leakage currents during movement or when fully in. Same procedure with the right arm. No change in leakage currents in either. I doubt this is a light affect. If some light was incident on the left hand detectors, moving the detectors should have changed the amount of light on them in some way, reducing the leakage current. Similarly if light can hit the detector when fully in for the left arm, some should be hitting the right arm when it is fully in too, but no change observed on the right arm either. No light sources found on interaction chamber, baking jackets covers all ports.

Movement for several repeptitions with the pneumatic tried to see if this had any affect -> no change

Bias lines for DSSD1 and DSSD2 swapped around on the caen bias module. No change in leakage current for DSSD1 or 2. Channel on bias module not to blame.

Tried turning ion pumps off, no change on leakage currents.

Tried reverse biasing the detectors. Polarity for channels 0 (DSSD1) and 2 (DSSD3) swapped from -ve to +ve on bias module. Core and braid swapped on adaptor card. Completed VI curve when reverse biased for these detectrors. Obtain the same curve as with -ve polarity. Left at 100V for 10-15 minutes. Put polarities back to -ve, no change in leakage currents observed.

Opended up one of the diamond windows with bias off. Shone my phone light through the window for ~30 seconds. Closed window off again, biased, no change observed. Left detectors biased overnight. CH0 - 15.4 uA, CH2-14.7uA.

15/04/25

No change in leakage currents overnight. From gnuplot they look pretty flat overnight. Perhaps slight decrease.

Checked attaching LK2 jumper to aida09 (nn DSSD3). Could not reach other nn adaptor card. No effect on leakage current. Dismounted jumper.

New female connector mounted on aida08 and FEE remounted.

Restarted AIDA system by closing all windows and servers. Error on starup, could not connect to relay16 for FEE power.

Issue related to dew point interlock. Dew point sensor is very sensitive and any movement can cause it to trip. Sensor was not well supported on the coolant pipe. Sensor remounted with plastic zip ties. Issue resolved. Investigate some noise issues in the afternoon

After lunch I have noticed the leakage current have increased slightly. See attachment 5. CH3 is higher and appears to be fluctuating by 1-2uA. Turning off bias and going to cave to investigate.

Bias still higher and fluctating on CH3. Konstantin is in the ring, but he has not started any works yet, some grossmontage are also in the ring and are working on the new source. Could this be affecting us? Either way, will startup daq to check rates/noise etc.

Previous settings applied (i.e all channels back to LEC). Have lost the dew point interlock again!

I have suspended the dew point sensor in the air for the time being -> need to put a dummy in.

Grossmontage working on ion source have left and leakage current on DSSD3 is no longer fluctuating -> coincidence? (attachment 6)

AIDA started again. Rates appear OK except for on 3,4 and 15. (see attachement 7,8,9)  Note the rates on 9,10 are reduced compared to previous elog entry. Note pulser off. Note on aida startup aida16 clock status fail and ADC calibration fail for aida 6,14 and 16

16:00

We again see DSSD3 leakage current fluctuating. I will head back to the cave to check if anyone is working again? Nikos and davide working on the target but can't see how they would impact the leakage current (they were only installing a support for the new turbo)

DSSD3 remains fluctuating even now they have stopped working.

Pulser on. Same settings as elog 664 -> freq = 10 Hz

Overall pulser widths look bad, rates (ADC data items) look okay (~1000) for all except aida03 and aida04 (>250,000). Again rates on aida09 and aida10 are good although the widths are poor. One change I did make was to ground the FEEs to the CRYRING ground wheras previously they were grounded to the coolant pipe. I may try putting them back onto the coolant loop to see if there are any changes. Note grounds all around have not been examined yet.  Attachments 10-17 with pulser on.

Moved grounds back onto the coolant pipe -> no effect on ADC rates.

Also tried lowing slow comparator theshold down to 150 keV (0xf) for most channels (except aida3 and 4). See rates attachment 18.

There appear to be issues with Shahab's caenlogging program. It crashes occasionally, with an error indicating the number of columns in the terminal is incorrect. We will have to ask Shahab.

For now

1. Start the caen_screen.sh script on nnrp1 (aka CARMEMotorsPi -  why was it renamed? It should stay as CARMEMotorsPi to avoid duplicate names).

This starts connect to the caen power module via TTY inside a screen called caenhv. Currently on desktop 1

2. On nnrpi1, start the caenlogging program --settings caenlogger_settings_gsi.toml

3. On carme-gsi, in ~/Programs/caenlogger start the gnuplot script

If the caenlogger script crashes, restart it on the second terminal

More investigations required on the crash.

There was some tidying up of the CRYRING hall in advance of this week's EC evaluation meeting at GSI.

CARME equipment stored in central area of the CRYRING hall has been moved to the roof storage area near rooms 2.033/4 and a cupboard near the main entrance to the CRYRING 
hall - attachments 1-2.

Water flow and dew point sensors have been installed on the outlet and inlet cooling water manifolds respectively.

Outputs indicating good water flow and ambient temperature above the dew point are connected via an interlock box (constructed by Peter Black)
to the USB-controlled ac mains relay which provides remote control of ac mains power to the AIDA FEE64 PSUs.

The interlock box (see attachment 1) has 

1x 24V dc power input (ac mains transformer)
4x sensor inputs (1x dew point, 1x flow and 2x unused, dummy cable inputs)
4x outputs (1x connected to USB-controlled ac mains relay, 3x unused)

When all sensor inputs are OK, 4x yellow LEDs (corresponding to each of the 4x sensor inputs) are illuminated and visible through the transparent
lid of the interlock box - see attachment 2
The USB-controlled ac mains relay yellow 'water' LED is illuminated if interlock is OK - see attachment 3
