TO-DO for 11.04.2024
- Try bringing bPlast drain wire ground back to the PSU ground for PN 300 and R&SRMP4040.
- Recheck the downstream detector bias and ground scheme.
-
9:27 Restarted AIDA and hit go at 9:54. Situation the same as it was in the evening of 10.04.2024. 10 out of 16 FEE64s in good condition. Waveforms of aida16,
TEMP OK - HV OK. See attachments 1-6.
10:20 We grounded the output of the R&SRMP4040 to to the drain wire ground of the bPlast ribbon cables and the output of the PN 300 PSU that is powering the booster boards. Results given by attachments 7 -11. We only saw a marginal improvement in the overall noise condition.
10:32 We connected the ground of the frame to the drain wire ground, that is also mutually connected to the ground of the R&SRMP4040 output ground and PN 300 output ground. Results given by attachments ???. We did not see any improvement in the overal noise condition.

17.15 bPlas ON -
Current bPlast ground configuration:
bPlas current ground configuration - drainwires of all ribbon cables excluding short side (cont. with snout) are grounded back to the bPlast R&SRMP4040 PSU, on the 29 V output. 4 V PSU to booster boards are floating, output of PN 300 is grounded to the PSU. The mesytec PSU, that also powers bPlast SiPMs at
29V is not grounded to anything but the frame. Snout is currently light tight, I suspect internal radiation from FATIMA.
It is noted that bPlast current draw fluctuated significantly (+/- 300 mV) as a result of thresholds set to the detector. I tried to set the thresholds HIGH to stabilise the bPlast detector as the power draw is fluctuating greatly.
AIDA noise very good
ADC data item stats - attachment 42
12x < 20k, max 83k (aida04)
per FEE64 Rate spectra - attachment 43
To Do list
- separate 29V (low current) and 4V (high current) return paths/ground refs
- The mesytec PSU that powers the bPlast detector is running to frame, it might be an idea to ground ribbon c

Just another manic magic Monday, ....
Taking over Betool's AIDA shift. All is good.
This shift's first hour has been eventless. Temperatures, Rates, bias, all look good.
01:15: AIDA04 is down again. DAQ shift crew informed.
01:27: AIDA04 is back and shift crew has been informed.
01:30 Checks:
Bias and leakage current - Attachment 1-2
Temperatures - Attachment 3
ADC Data item - Attachment 4
Rate Spectra - Attachment 5
UCESB - Attachment 6
Timestamp checks - Attachement 7
06:00 It has run very smoothly.

14:52 Attachment 1 shows low energy spectra. AIDA06 shows strange baseline, possible double-hit?
15:06 Systems checks fine.
Master clock failed (no master clock)
all checks passed
memory checks all around 38k as normal
Attachment 2: Temperature check all normal except aida01 virtex temp slightly over 65 degrees
Attachment 3: Good event stats seem normal except downstream SSD seems to be high around 200k
Attachment 4: leakage currents seem normal at expected values
15:16 Merger working for all FEEs
tape server is on but no storage
data rate is around 25 MB per second (high but consistent with the high stats of downstream SSD)
ASIC controls checked and are all OK

ALL FEEs in downstream SSD are high
16:21 included low energy pulsar peaks (Attachments 5 & 6) and waveforms for all FEEs (Attachments 7 & 8)
16:25 included rates, note not to common scale in y (attachment 9)
ASIC settings file 2019Dec19-16.19.51 but some others are on 2019Oct31-13.24.23
Did not seem completely reproducible?
We carefully checked all the individual FEE and ASIC settings, and they are all the same (except shaping reference), with NO 0xad
Now we made sure they are all using 2019Dec19-16.19.51 (which we had saved first on a good one)
19:15 Update
There is a safety interlock box in S4 to monitor humidity, dew point, temperature, etc for safety.
It had a loose solder connection, and when someone moved it out of the way, the interlock was tripped.
After some debugging, the interlock is now in a more stable condition, but a lot of power was cut from AIDA systems
One unusual thing was that one of the RPi systems got a full /var/messages (or similar) and ate all the available disk space
This meant that ssh -X (to, e.g., activate putty) could not work, giving a permission denial error (ssh connection was allowed, but not X11 forwarding)
Now we have brought back up the AIDA systems and should run through the checks
Most system checks look good (except some calibration errors)
Temps were running high until we reloaded the ASIC settings, then the temperatures began to cool
Bias and leak currents attached as #10
Temps as #11
Stats as #12
19:50 Started writing to disk so that we can do an implantation depth profile. Will analyse near online using AIDASort.
21:45 Stopped writing to file -> Runs where AIDA thickness were investigated corresponds to R3_62 to R3_72
A rough method using the rates histogram was used to judge roughly when depositing in each histogram - see attachment 12 (Stopping in 2)
Can match to the FRS files to work out degrader thickness with timestamps (File stopped at Mon 09 Mar 2020 09:44:51 PM CET
21:51 AIDA running to no storage again |

SC42 L/R currently report c. 4.5kHz
Note that we currently see a higher fraction of events in DSSSD#2 cf. previous setting so multiplicity assumption may be low
If we assume multipicity = 6 => implant rate ~ 1.0kHz in spill or 3200 implants per spill
we are probably somewhere in between

Took over the shift from Marc.
10.51 Added screenshots to illustrate erroneous data from Grafana (AIDA) - attachments 18-19
Compare to the CAEN HV control terminal (attachment 15) which shows the expected values. Have email'd Nic & Helena. TD
10.55 Noticed that the CAEN HV control terminal is showing the corerct data but on the wrong line of the display (attachment 15). Enter commands q (quit) and d (display) to restart display - the correct data now appears on the correct line (attachment 20).
Grafana (AIDA) is now reporting data correctly too (attachment 21).
Summary - CAEN HV terminal display issue ( c. 10.05 - 10.55 )
Note the correct data/values continued to be shown. Leakage current shown correctly by both Grafana and CAEN HV control throughout.
Conclude this was a display issue - not a change in the operating parameters of the CAEN N1419ET.. Data should be OK.

15:40 reseated FEE64s adaptors of aida01, aida09, aida13 & aida16.
TEMP OK. HV OK. System wide checks all passed excl. aida07 ADC calibration, see attached.
Histograms and rates look same as previous, reseating aida01 seems to have worked. aida16 still unhappy.
re-reseated aida16. 16:19 - appears to have fixed the problem in the channel.
Pulser test + connected.
bPlast ground removed from frame.
To-do:
- Need clarification about links connected on AIDA n+n FEE64 adaptor boards. Currently, the situation is given by the attachment 8 & 9.
- Fix BB7 grounding, continuity between snout and frame observed.
- Pulser walkthrough for n+n, can do p+n when convienient.
18.30 Noted FEE64 ADC stats now significantly higher ( attachments 9-10 ) cf. earlier this afternoon (attachments 1-2)
DSSSD bias OFF. FEE64 power OFF.

Starting a new night shift - All good
1am full check:
DSSSD bias & leakage current ok - attachment # 1-2
FEE64 temperatures ok - attachment # 3
ADC data item stats - attachment # 4
Merger ok - Attachement # 5
Tape service - attachement # 6
2:30am: AIDA02 FEE stopped working. DESPEC main DAQ was alerted and remobe AIDA from timestitcher while I was restarting AIDA DAQ.
2:45am: AIDA02 FEE is back and AIDA has been added to the timestitcher again in the main DAQ.
The AIDA runs at the time of the crash to look at are R7_348, 349.
All spectra were zeroed at this time and checked.
4:00 am full check:
DSSSD bias & leakage current ok - attachment # 7-8
FEE64 temperatures ok - attachment # 9
ADC data item stats - attachment # 10
Merger ok - attachement # 11
Tape service - attachement # 12

6:00am full check:

Merger ok - attachement # 19
Tape service - attachement # 20

6:30 the nearline/offline analysis team reported possible noise issue in DSSD#2 and asked if the threshold were changed at any point. I can't find any mention of changes in the elog.
I've not done a setup of the all DAQ when AIDA02 fee crashes earlier this morning. I just did a setup of the merger. Thus I don't think the threshold have changed when I stopeed and restarted the DAQ.
I can see that currently slow comparator threshod are set to 0xa for most of the DSSD2 fees except for AIDA06 which is set to 0xf. I'm not sure this is the thershold we would need to increase. Something to check during the next shift.
In the UCESB window I can see that the number of decay in DSSD2 is double the number of decay in DSSD1 while the number of implant is similar. Looking at other shift it looks that this was alsready the case in prvious shifts.
