Tue Nov 5 15:19:35 2024, TD, S505 offline analysis R5_780 - R5_814 24x
|
Offline analysis of data files S505/R5_780 - R5_814 (corresponding to MBS data files 73-74)
Can find an analysis of alpha background runs at RIBF, RIKEN for comparison at https://elog.ph.ed.ac.uk/AIDA/816
Beam off - background runs without sources
MBS 73 27.6.22 09:33-11:33 CEST https://elog.gsi.de/despec/S505/204

FEE64 configuration
FEE64 a b c d
DSSSD#1 3 4 1 2
DSSSD#2 7 8 5 6
p+n junction FE64s odd numbered
Data analysis assumes
- all LEC ADC data channels with valid ADC offset included (474 of 512 channels)
- no clustering
- no p+n junction side - n+n Ohmic side correlation time gates
- valid LEC events
0 < p+n junction side multiplicity < 8
and
0 < n+n Ohmic side multiplicity < 8
Attachments 1-2 - per DSSSD p+n versus n+n multiplicity
Attachment 3 - per DSSSD x versus y
Attachments 4-5 - per DSSSD p+n versus n+n energy (20keV/channel nominal)
all combinations of per DSSSD p+n junction and n+n Ohmic energies
with projection of data within window onto x and y axes
too many events for natural (U decay series) background
off leading diagonal correlations anomalous
transverse width of leading diagonal correlation wider than expected - ADC offsets OK?
Attachment 6 - per FEE64 WR timestamp (32.768us/channel)
FEE64 sync test using pulser data - looks OK
Attachments 7-14 - per FEE64 ADC spectra (5.6keV/channel nominal)
note common x/y scale - pulser peak height proxy for peak width
per FEE64 1.8.L pulser peak widths (ch FWHM)
1 11.43
2 16.58
3 12.52
4 17.54
5 9.10
6 12.22
7 17.03
8 16.09
3 of 4 p+n junction FEE64 good (<70keV), 1 of 4 n+n Ohmic FEE64 good - all others < 100keV
Pulser peak indicates noise/gain/offset stable throughout background runs
Attachments 15-22 - per FEE64 ADC spectra (5.6kleV/channel nominal)
observe broad peak-like structures (c. 2.8MeV) in first channel of most ASICs?
Attachment 23 per DSSSD p+n versus n+n energy (20keV/channel nominal)
valid LEC events
p+n junction side multiplicity = 1 n+n Ohmic side multiplicity = 1
Attachment 24 p+n FEE64 #0 energy versus each of n+n FEE64s (#1, #3, #5 and #7) energies (20keV/channel nominal)
valid LEC events
p+n junction side multiplicity = 1 n+n Ohmic side multiplicity = 1
Attachments 23 & 24 do not unambiguously identify which FEE64s are attached to which DSSSD

Everything appears to be running smoothly. Attachments 1-4 were taken around 16:00
DSSSD Bias & Leakage Current - Check: OK (see attachment 1)
FEE64 Temperature - Check: OK (see attachment 2)
ADC Data Item Stats and Spectrum Browser - Check: OK (see attachments 3 and 4)
Another set of screenshots was taken around 18:00, and everything looks good.
DSSSD bias & leakage current ok - attachment # 5-6
FEE64 temperatures ok - attachment # 7
ADC data item stats - attachment # 8
Merger ok - Attachement #9
Tape service - attachement # 10
ucesb - attachment #11
At 19:17, AIDA03 temperatures gave no response (see attachment 12), but after two minutes, they returned to normal.
I noted that the bplse in ucesb has no data (see attachment 13). It may need to change the disc thresholds again
it does not affect AIDA
At 19:30 most aida temperature are high and I spoke to people on site via zoom one of them she is working with AIDA so she was able to help. She called Nick and it is found that there is a problem in the cooling system so she stopped AIDA
At 22 the cooling system fixed and Nic and the other person on site restarted AIDA

Tom thinks everything appears ok with AIDA
Have converted WR timestamp to data/time - see attachment 40
At the ~second timescale AIDA WR timestamp looks OK, i.e. no gross errors. Will need to check correlations with other detector sub-systems to confirm WR on the ~us time timescale..
However, ~10us offset reported by DESPEC online crew is correct (AIDA timestamps data at a later point in the signal processing cycle than other detector sub-systems). Have suggested online crew contact Nic or Calum to check what the AIDA WR timediff spectra should look like.

Elog went down around the end of the last shift, so final screenshots were not uploaded at that point.
However, AIDA appears to have contuned running smoothly in the interim (at least until 22:00).
Attachments 1 - 6 were taken around 16:00, 7 - 13 at around 18:00 , 14 - 18 at around 21:00.
Another set of sceenshots taken at around 23:00 - attachments 19 - 26.

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.
