DSSD Snout was reassembled to install the second bPlast (downstream)
(fig 1)
Ribbon cable for aida10 was replaced (DSSD3 upper)
All DSSDs bias again (see fig 2)
Alpha run in progress - channels OK with 2 exceptions (fig 3)
- aida10 still recording minimal to no counts
- channel 55 aida08 reading lots of data even with comparator 0x64 - corresponds to DSSD1 strip 0 (bottom strip)
possible ground/cable issue? will check when access possible (fig 4)
Unusual MIDAS error noticed (fig 5) - restart of HTTPd fixed it |

Fig 1: 2D hit pattern of each AIDA DSSD for MBS run 24 (40Ar primary beam, centred)
Low statistics in DSSD2 partly due to low energy deposition
Fig 2: Position according to TPC42 (ca. 2 metres before AIDA)
Fig 3: 2D hit pattern of DSSD 1 for MBS run 37 (34Si fragments, no PID gate)
-
Bottom part of AIDA noticably cut off - rotation in DSSD also noticed (not an issue)
Snout was investigated and platform was discovered to not be fully level by Bogdan using a laser level - he has adjusted it so that the AIDA snout is now level to within 1 mm.
(The beam right side was previous 4-6mm below the beam left side)
Y cut in fragment run is currently of unknown origin. Optics are being investigated

15:30
TD found the merger was running at ~43 Mb/s
The odd-numbered FEE64s all had significant (>200k) disk rates
ALL LEC/MEC fast discriminators and increased slow comparator from 0xa to 0x14
Merger rate dropped to a more nominal value like 2.3 Mb/s
Settings not saved
40Ar beam 300 MeV/u expected, but SIS problem at the moment.
23:00
Leak currents are stable as previously (20-21 Nov) and entered to Google spreadsheet
S4 vault is closed.
Presently AIDA is running without tape storage
System wide checks:
Master clock / aida01 sync reports error as expected;
All white rabbit decoders fail, but they are just off by 1 bit (no problem)
Everything else okay.
Stats look okay, but keep in mind above discriminator threshold -- see attachment 1
Temperatures fine -- see attachment 2
MBS looks okay -- we see a possible hint for the 1 bit difference with an "unexpected data word" -- see attachment 3
Data rate is 1.7 Mb/s, merger okay -- see attachment 4
23:30
Now we wait for the beam
00:05
Attachments 5-11: results of system wide checks after collecting sync errors and WR errors from baseline - all ok

NH | New Bias & Waveforms |
HV core (-160 V) now attached to bottom 3 FEEs (with grounded kapton)
DSSDs bias OK, leakages unchanged
No appreciable change in waveforms
Some estimates
aida01/aida05/aida09 VHF noise: 5 channels frequency = 10 MHz ?
All FEEs:
Oscillation at ~25-35 channels = 1.4 to 2 MHz ?
Varies a bit with each FEE.
No obvious issue with upper FEEs unsure why 10 MHz is present - fee09 has been replaced but showed it before as well.
Lower frequency noise on every FEE may be ground noise from e.g. switching PSU?
No more access to S4 to check thoroughly again.

CA, CB, DK, NH | 20/21 November Night Shift |
21:35 (NH) - A few merger timestamp errors were appearing - Decided to powercycle all FEE64s, all checks OK.
No Screenshot due to forgetting before I closed merger
FEEs were often not stopping properly and needing merger reset as well.
Beam Plan:
40Ar 300 MeV/u Primary Beam
and/or
34Si Fragment from Ar
22:45
FEES were restart near these timestamps in the TapeData, evidently
-rw-rw-r--. 1 npg npg 2.0G Nov 20 21:17 R1_361
-rw-rw-r--. 1 npg npg 2.0G Nov 20 21:36 R1_362
Run number was kept the same (Tape Server was not stopped @ FEE restart?)
All system wide checks are okay (except of course the master clock fails)
Temps look okay (attachment 1, dated 21/Nov by mistake)
Leak currents all around 0.9 uA as before (attachment 2)
Stats are behaved. We don't have beam yet (attachment 3)
Merger and tape server happy (see attachment 4)
Data rate histos while beam is still off (see attachment 5)
==Nov 21==
0:00
TD noted that the data rates have gone up at some point (about double).
Now we increased the slow comparator thresholds from 0xa to 0xb (data rate drops from 24 Mb/s to 16 Mb/s).
We increased it again from 0xb to 0xc, but near that time the beam was also turned on, and the data rate was about 25 Mb/s.
Beam was turned on near R1_472 or a bit earlier.
TD requested waveforms, but at the moment they are not appearing. Will enable WFs after a condition change.
Beam seen in all three DSSSDs, see attachment 6. Beam was turned off before I could get more screencaps.
Degrader change ... near R1_481
00:32 waveforms now enabled under Run Control. They also appear to be enabled on ASIC1 undre LED and Waveform controls. However, we are unable to see the waveforms in the relevant histograms.
00:44 3 g/cm^2 inserted R1_488
00:45 3.2 g/cm^2 degrader in R1_489.
1:00 Several degraders and combinations are being tested since last note.
1:10 It seems 1 g/cm^2 of energy loss is not accounted for by LISE++. Trying to understand the reason.
1:28 Satisfied with a total degrader thickness of 2.6 g/cm^2 -- seems to calculate that fragments should implant mainly in DSSSD2? Issue seems to be resolved updating the LISE++ file.
Near R1_507
Can see the implant samples attached as #7 and #8
1:43 According to the stats, most of the beam energy is being deposited in DSSSD1. See #9.
Present beam burst repetition is around 0.1 Hz (each ~10 sec)
2:00 better example of stats histos (see #10)
2:45 tuning the FRS degraders (ones for RIB separation rather than AIDA implantation depth).
3:17 Just started fragments. Disregard previous filenames with "34Si". Finally no degrader in the FRS was needed to get Z separation.
R1_559
As the DAQs are not synchronized, a quick call to the BNC PB-5 pulser shifiting from 2 -> 50 -> 2 Hz was used to make a signal burst.
S4 degrader is 5.2 g/cm^2
3:22 Updated biases in Google Sheets.
Having trouble seeing the fragments in the AIDA histograms. Since we just started fragments, zero the histos.
3:35 Attachment 11, with 34Si fragments as Stats. Difficult to click Update on the Rates at the right time.
From the beam monitors, fragments should be at around 3000 cps.
3:45 (Up to now, some optics tuning with slits, etc)
3:46 Optics settings accepted, AIDA at R1_572, accept this condition for data runs on ~34Si fragments.
3:47 Sent a pulser burst 2 -> 50 -> 2 Hz
3:50 zero histograms again.

CA, CB, DK, NH | 19/20 November 2019 - overnight shift |
19 November
Waiting for 40Ar beam to be delivered for tests.
Objective today is to assess degrader thickness suitable to stop 40Ar in 2nd DSSD layer.
Energy expected at 300 MeV/A, around 1E3-4 beam intensity - to be determined.
Tomorrow fragments could be expected.
DSSD / FEE64 pairing as follows
DSSD3 (most downstream): FEEs 9,10,11,12
DSSD2 (middle): FEEs 5,6,7,8
DSSD1 (most upstream): FEEs 1,2,3,4
+plastic scintillator furthest upstream
New AIDA Google spreadsheet created with leakage current, to monitor them during beamtime. First entry added. Bias attached.
https://docs.google.com/spreadsheets/d/12hgbrywB10hGsKt5uc2HnLfZymh8_uvM6cEASbbqnBE/edit#gid=813167023
DESPEC platform has already been moved. No effect on rates - see attached. FEE1 is missing one channel. FEE9, 10 noisy as expected. See attached.
System wide checks *all OK* except
Master clock failed (normal)
ADC calibration fails on 6 and 12. Recalibrated via FADC Align. All OK now.
MBS transfer OK. See attached.
Good event statistics OK. See attached.
FEE64 temperatures OK. See attached.
Merger and data rate OK. See attached.
Waiting for beam.
20 November
01:07 - Still no beam.
System wide checks OK.
Stats OK.
Temps OK.
MBS OK.
Merger and data rate OK.
02:35 - Beam is expected soon
Tried enabling writing data to disk. Merger crashed. FEE64 stopped responding to commands.
Reset Merger. FEE64 now respond to commands.
Tried enabling writing to disk again. Merger crashed once more. Reset merger.
Reset Tape Server interface. Now writing to disk.
No data currently being sent to MBS, but operators say they "are adding a new detector". May be normal.
DAQ & Merger going OK. Writing to Nov19/R1
No beam yet.
Temperatures OK
System wide checks OK
Stats OK. See attached.
MBS not working.
Merger and data rate OK. See attached.
~02:48 Beam on. 40Ar. 300 MeV/A, 500 pps. Degrader settings unclear.
03:54 Degrader settings have been changing between 4.5, 1 and 6 ug/cm2
Currently on 6 g/cm2.
AIDA seen through MBS shows no HE on detector 3, and Det 1 and 2 show no counts on positive y (FEE6 and 1). That is not the case from MIDAS.
04:30 The aim of the tests above was to have no 40Ar at all in DSSD3. It does not appear that 6 g/cm2 is sufficient, as we still see events. The reduction between 1 & 2 vs. 3 is about a factor of 2-10 depending on ADC channel. See attached.
~04:30 Moved to 6.2 g/cm2 degrader. See attached.
~04:45 Moved to 5.8 g/cm2. See attached.
~05:09 Moved to 6.4 g/cm2. See attached.
05:31 High energy channel spectra (1.8.H) for all FEE64 w/ 6.4 g/cm2 degrader - See attachments 13 & 14
05:38: Moved to 1.0 g/cm2. See attached. Difference is not huge which may indicate these spectra are misleading, as partly expected. A more detailed analysis will be carried out off line.
06:00: Beam stopped. ~R77. AIDA keeps running background over the day. Beam should restart around 11 pm later today. |

NH | [HowTo] MBS for AIDA (Nov 19) |
For MBS integration AIDA forwards its data to an MBS Foreign Data Receiver (FDR), currently the PC assigned for this task is x86l-94.
To start the MBS system do the following:
Connect to the MBS FDR: ssh despec@x86l-94 (Ask local for password)
cd to the AIDA directory: cd mbsrun/nov19/aida_to_mbs
Start mbs: mbs
Startup the receiver: @startup
Now open the MBS relay for MIDAS (far right icon on the top)
Check both terminals (Relay & MBS) report a connection
In another terminal ssh into the FDR and run rate to monitor the data rate in MBS
For data to be transferred the Tape Server must be GOING but can be in No Storage mode if no MIDAS storage is required.
--
For experiments MBS file saving is handled by the DESPEC time sorter which merges all the subsystems together.
For testing you can write files from x86l-94 using the following commands
connect rfio XXX -disk
Where XXX is an Linux PC (ask local for a PC)
open file /path/to/file_ first=1 size=2000 -auto -rfio
This opens the file, writing in 2GB chunks
clo file
This will close the file when you are done
--
It is possible to restart the MBS relay at any point if the connection seems to have failed, also confirm the Tape Server is GOing |

NH | Alpha Analysis (11.11.19) |
Analysis of approx 20GB of data since Thursday night (not continuous - estimate of hours incominG)
Figures 1-3: Energy Front vs Energy Back (No F-B energy gate)
Figures 4-6: 2D hit pattern
Figures 7-9: 1D hit pattern
aida10 does not seem to be reading out still, unsure of reason? Looks fine with pulser.
Slow comparator not setting or unusual gain?
Otherwise good |

An update/clarification:
Although the upper bits are zero I believe actually it is a total failure to synchronise to WR:

NH PJCS | Report: aida10 database corruption |
If ypou now check the actual values in the aida10 Options screen are the correct ?
It can happen that corruptions once loaded are propagated when Options are generally saved.
Looking at the dates the files were modified does that make sense to you. It doesn't look as if the corrupted database was changed except when they all were ? Can you check ? Have you checked the other Options files ? I seem to recall that RIKEN AIDA had a program to to this ?

Hi, see the attached files in the original comment. I think the BACKUPCorrupt is quite old now.
The Options data gets corrupted and for example the ASIC folder gets set to 'undefined' which I think is why the ASIC data loads incorrectly.

This looks like the Options not the ASIC data. That will be in the CONTENTS file of the FEE64 named directory within the dated EXPERIMENT directory. Looks like the latest is at /MIDAS/DB/EXPERIMENTS/AIDA/2019Oct31-13.24.23/aida10 ?
A quick look at this file and it looks normal , not all 0xad ?
Looked at the Options file in the /MIDAS/DB/EXPERIMENTS/AIDA/Options.BACKUPCorrupt/aida10 and the worst bit is the name of the Data Acquistion program. That could welll cause you problems with readout as it won't understand some of the new data.

Often aida10 database seems to get corrupted (ASIC values are all 0xad)
Unsure why it's only aida10, might be related to weird alpha rate behaviour at the moment.
Attached is corrupted database and correct database
