09:59 Noticed that the right hand ribbon cable for aida07 was offset vertically by 1. i.e. Only 1 of the 2 rows of pins in. Unbiassed detectors and reconnected.
Rebiassed detectors - leakage current on DSSD2 increased to 9.96uA - Attachment 1
Power cycling FEEs
Following restart the FEEs show some improvement in rates - attachment 2
Rate spectra - attachment 3
Still issues with aida11 in the rate spectra (Likely a misaligned ERNI connector)
Pulser on rate spectra - attachment 4
Pulser off rate spectra - attachment 5
We can see that with the pulser on there are events in the channels in aida01 and aida11
With the pulser off these channels disappear.
ERNI connector is then likely aligned the issue is more likely the DSSD ribbon cable is misaligned.
Taking bias off to investigate.
10:39 Could not observe anything out of alignement about either the connectors or the adaptor boards
Note that after pushing on the connector AIDA01 had largely recovered
13:30 Top of snout taken off while mounted in S4. It was observed that one of the ribbon cables for aida11 was off by 1 row.
This was corrected in situ and the snout was put back together and made light tight again.
Oddly leakage current still the same - DSSD2 has come down though - attachment 6
FEEs powercycled for new tests
Half the channels in aida11 had appeared again
Took apart once more and found the other header also off by one row which has been corrected
FEEs powercycled for new test
All of aida11 now showing - attachment 7
Statistics at 0xa shown in attachment 8
All p+n for DSSD1 are good (aida01, 03, 09, 10, 11 and 12)
p+n for DSSD2 are so so (aida05, 07, 13, 14, 15 and 16)
All n+n 2, 4, 6 and 8 are poor still
14:50 p+n waveforms - attachment 9
n+n waveforms - attachment 10
Current jumper configuration
LK1 (Bias ground) on FEEs 6 and 8
LK2&4 on all p+n
LK3 on aida03 and aida07 (Bottom middle)
15:00 Investigated whether there was a light leak. Placed black material over snout.
Leakage on DSSD2 dropped to 5.6 - attachment 11
There was a light leak
Stats have decreased slightly - attachment 12
16:00 Move raspberry pis atop 5mm alminimum plate to keep away from FEE64 PSUs
No change
16:30 Remove pulser network from all FEEs
Rates get noticably worse in many FEEs... why?

Possible ideas include braid touching things it shouldn't (Adapter PCBs?) |

Tue Jun 28 10:11:35 2022, OH, NH, MIDAS Data Aq V10
|
11:11 Rebooted FEEs and changed aidacommon in /MIDAS/linux-ppc_4xx/startup to point to the new V10 DataAq that Patrick produced
When using V9 the Merger statistics reported WR items at twice the rate of ADC data items.
i.e for ever data item we were sending and info code 4 and info code 5 item sending 192 bits of data vs 64 for just the data word
This was causing significant deadtime when FEEs were running in the range of around 200kHz. These WR items were not reported by the MIDAS Acquisition server but were in the Merger statistics
Patrick has produced V10 which removes these.
When running V10 we can confirm in the Merger statistics that this rate is no longer determined by the ADC data rate and instead controlled via Sync Rollover Target in GSI WhiteRabbit Control.
WR items for 0xE - attachment 1
WR items for 0x7 - attachment 2
However we see in the NewMerger terminal the message shown in attachment 3 frequently.
Also we note that the merger time error counter is also going up.
Our thoughts for this are we have a rollover issue (Is the merger expecting the rollover of the LSB to be one value when the MSB is updated but MIDAS is happening on another?)
Are we having dead time issues which is causing time warps?
Does each buffer from the MIDAS Data Acq start with a full WR timestamp?
aidacommon has been changed back to point to V9 to not cause issues when we run the DAQ and forget we changed it to be this way? |

They are now placing a thick plate in front of AIDA to block the fragments while they beam tune.
11:38 They have found the issue with the degrader and have corrected it.
We now see next to no implants in AIDA as expect.
Histograms reset at around 11:35
Layout 2 shows very few implants in 5 minutes - attachment 7
12:08 The high implantation rates of ions into AIDA is clearly seen in the large transients on the leakage currents - attachment 8

A note on the statistics. aida11 has doubled in rate today and aida07 has gone down somewhat.
After talking with the DESPEC locals. Helena and Juergen entere at S4 at 9:40 German time.
They stood on the platform but stayed away from the snout, they added two channels to the scope and adjusted the ribbon

aida11 - 72901, 95942, 176139, 93799 - more than doubled but large drop in rate back below 100k will keep an eye on

no timewarps so we are not losing anything.

Restarted but no stats in aida04
It did not recover from a reset
Telnet in and did a reboot command
09:10 Finally recovered issue was it was not linking to merger
There is an options issue with aida12. The ASIC settings had become undefined and there are no histograms
Manually set the ASIC settings for aida12. Rates look as expected after
Will try to reset once beam is back

bunch of timewarp errors in ucesb, no errors in MBS relay terminal though
now see error in MBS relay!
"Warning: At least one MIDAS block missed in relay" Warning was set up by NH and OH to detect if the LSB of the first ADC data item in a block is less than the LAST LSB of the previous data block. It then iterates the info code 4 and if needed 5 stored before resetting the LSB stored.
It triggered 63 times.
I have checked all the files in the vicinity and there are no timewarps in the MIDAS data visible to TD's analyser

It might be worth considering decreasing the time between the flushing of slower FEEs. Is the Merger waiting for the slower data and causing ‘deadtime’ in the faster ones. Perhaps consider this as a
balancing across the system? |

Thu Mar 4 11:16:13 2021, OH, Further cases of possible database issues
|
During testing for the S452 experiment yesterday we were running through the steps of a restart.
The FEEs were not powercycled at this stage but the MIDAS server was restarted.
Initial setup went smoothly and no issues were encountered during setup.
NewMerger and TapeServer were both setup and set to going.
Upon ''Going'' the run control the data transfer for aida09 dropped out.
Going to the NewMerger it could be seen that data was making it through and data items were being merged.
The tapeserver however was seeing no data and neither was the MBS dataspy.
During this time the FEEs became unresponsive likely as their buffers filled. Trying to reset gave the attached errors.
Checking the folder manually it could be seen that the Options file was there.
At this point a powercycle was pewrformed but upong 'Going' the DAQ the same issue was again encountered.
This time we were able to recover control access to the FEEs by running multiple NewMerger sessions which helped clear the buffers.
During our search for the problem we looked at the Options from within MIDAS and could not see anything out of the ordinary.
We also tried restoring the Options from within MIDAS.
We again reached the same issue with the tapeserver.
At this point we restored the Options folder from by copying manually within terminal.
Following this we were able to start the DAQ normally. |

There has been no beam for much of the day. It was lost at 13:00 and not regained until 22:00 German time.
At some point during the day the White Rabbit timestamp cable was unplugged from AIDA. This caused it lose correlation with the rest of the system.
At first a reset and setup was performed to try and regain correlation but that did not prove successful.
A full powercycle was then performed at ~22:30 German time which upon restarting the DAQ solved the issue.
The plan is to overnight run some fragments, for the purposes of observing the isomers. This data is not essential and as such we will not be writing to disk.
Beam plug is in front of AIDA. This is causing a huge spike in the Ge. |
