 Wed Dec 11 14:46:21 2024, TD, JB, CC, MP, Mounting of AIDA, bPlast and BB7 for test 
|
Snout assembled for detector position and timing test.
The planned test is to use a BGO with a 22-Na source and the implantation stack to characterise the timing and position of back-to-back 511 keV events (proxy for mock beta decay event).
The implantation stack is assembled as follows:
Upstream ----> AIDA test frame (as a spacer) ----> AIDA DSSSD (3208-3/3208-21/3208-22, Upstream AIDA used in S100 & S181, April 2024) ----> bPlast (Downstream bPlast) ----> BB7 (mounted in test frame connected to AIDA adaptor) ----> Downstream
The AIDA DSSSD condition seems to be the same as when it was dismounted after S181 and it, apart from some specks of dust no bond wires appear to be broken to the naked eye.
BGO signals appear on the scope with a 22-Na source but the response is quite messy.
17:36
MSL type BB18(DS)-1000 24cm x 8cm DSSSD upstream position within snout using 8x upstream (23") ribbon cables
MSL type BB(DS)-1000 positioned downstream of downstream bPlast within snout using 1x downstream (29") ribbon cable. For BB7 'isolated' Right Coupler Kapton PCB replaced by unmodified Right Coupler Kapton PCB.

Mon Dec 9 12:28:01 2024, NH, CC, MP, Test of BB7 on AIDA Electronics
|
BB7 connected to aida07, sitting in a cardboard box
Update Tcl/Tml files in ASIC, ASIC4 and sys.tml frm PJCS email to allow setting per-ASIC polarity on FEE64
Restart MIDAS@8015
Power on all FEEs
Note nnrpi is not responding to ssh... MP investigates if it ahs been unplugged
No, but a powercycle worked and fixed it
See error: /MIDAS/FEE_ASIC/aida06/ASICs.txt not found, create the folders
We see some data in the L spectra, and changing the settings from one ASIC seems to work properly
Stopped for CC/MP to determine the which ASICs correspond to p+n and n+n
Follow up: Alpha data overnight or source? |

Data analysis assumes
- all LEC ADC data channels with valid ADC offset included (1012 of 1024 channels)

- no clustering
- no multiplex timestamp correction
- no p+n junction side - n+n Ohmic side correlation time gates

- HEC energy difference +/- 1.68GeV
- valid LEC events

difference in WR timestamp between successive ADC data items > 2500
Attachments 1-4
per DSSSD p+n junction - n+n Ohmic strip time difference for HEC and LEC events (2us/channel) linear and log scale
- observe large (> 32us) time differences (on log scale)
- range of time differences increases with multiplicity ( DSSSD#1 cf. DSSSD#2 LEC events)
- distribution of HEC time differences can probably be understood in terms of most/all channels of ASIC being active during HEC event with low LEC thresholds
- AIDA is a triggerless DAQ producing streams of ADC data items *not* events
at high instantaneous rates when events are constructed they may become aggregated in time i.e. > 32us readout time of all channels of one ASIC
- To investigate impose additional end of event criterion
difference in first and last WR timestamp of event < 33us
Attachments 5-6
per DSSSD p+n junction - n+n Ohmic strip time difference for HEC and LEC events (2us/channel) linear and log scale
- blue original end of event criteria, cyan new end of event criteria
- as expected range of time differences is restricted to +/- 32us
- observe somewhat higher fraction of events with low time differences
DSSSD #1 10363098 of 16104322 (64%) events +/-2us
DSSSD #2 860454912 of 1766618199 (49%) events +/-2us

Attachment 10 per FEE64 LEC data rate (Hz) 268ms/channel: energy > 1500keV
- observe high instantaneous rate on spill
- rate dominated by low energy (<1500keV) events
- rate of higher energy events dominated by on spill events i.e. light ions as expected
- significant deadtime on spill for n+n Ohmic FEE64s, low deadtime off spill
- deadtime low/zero for p+n junction FEE64s on/off spill

Attachment 15 per FEE64 HEC data rate (Hz) 268ms/channel: energy > 1000MeV
- rate dominated by low energy (>1GeV) events
- all HEC events on spill as expected (note FEE64 #7 has a single hot channel which can be disabled in software)
- significant deadtime on spill for n+n Ohmic FEE64s, low deadtime off spill
- deadtime low/zero for p+n junction FEE64s on/off spill

DSSSD #1 ions stopped in DSSSD #1 i.e. DSSSD #2 HEC multiplicity = 0
DSSSD #1 shows x-y gate used ( 270 < x < 370, 20 < y < 90 ) to identify 166Tb implants
DSSSD #2 ions stopped in DSSSD #2 *and* in transmission (can establish which ions stop in DSSSD#2 from DSSSD#2 HEC energy versus DSSSD#1 HEC energy - see https://elog.ph.ed.ac.uk/DESPEC/672
Attachment 20
DSSSD#1 HEC energy (20MeV/channel) versus HEC-LEC dt (1s/channel)
DSSSD#1 LEC energy (20keV/channel) versus HEC-LEC dt (1s/channel)
DSSSD#1 HEC strip # versus HEC-LEC dt (1s/channel)
- Observe # events in every third channel is lower
- Probably reflects implant-decay correlation livetime
For example (choosing some numbers for illustrative purposes)
on spill: HEC livetime 75%, LEC livetime 75% (FEE64 deadtime common for HEC and LEC data) => implant decay correlation livetime 56%
off spill: HEC live time 75%, LEC livetime 100% => implant decay correlation livetime 75%
- Observe 'hot' x channels 315, 318, 321, 324 - disabled for further analysis
- Do not observe any 'hot' y channels
Attachments 21 & 22
DSSSD#1 per pixel HEC-LEC time (1s/channel): x,y,z gated to select 166Tb events
Naive (parent-daughter decay only, flat background) fit for data t=0-26s ( t1/2 = 27.1(3)s )
Fit ignores data for t=0, 3, 6, 10, 13, 16, 19, 22s to avoid bias of differences in implant-decay correlation deadtime
Suggestion of structure at c. 30s period? Does this reflect spill stucture? 10x spill cycles (30s), 9s spill off, ... etc
Sum of x,y,z gated HEC events (s2112 - see attachment 19) = 670441
Elapsed time of dataset 4h11m = 15060s
# pixels = 100 x 70 = 7000
=> # x,y,z gated HEC events per pixel = 670441/7000/15060 = 0.0064/s or mean time between x,y,z gated HEC event = 157s (estimate needs to be corrected for HEC deadtime)
Sum of implant decay correlations (s2220 - see attachment 21) t=0-150s = 273508 - flat background estimated as 150 x 500 = 75000 = 198508
=> efficiency c. 30% (presumably low due to implant-decay deadtime, LEC multiplicity, per pixel correlations and no clustering)
Summary
$64,000 question - what is the origin of the high instantaneous rate on spill for DSSSD#1 ? On my to do list.
Attachment 23
LEC multiplicity with/without HEC data in event
per DSSSD LEC p+n junction multiplicity versus n+n Ohmic multiplicity
per DSSSD LEC p+n junction multiplicity versus n+n Ohmic multiplicity z_hec=1 and z_hec=2
With HEC data
DSSSD#1 p+n junction multiplicity ~ 17, n+n Ohmic multiplicity ~28
DSSSD#2 p+n junction multiplicity ~ 40, n+n Ohmic multiplicity ~23
Assume 200Hz HEC events => DSSSD#1 LEC rate = 200 x ( 17 + 28 ) => 9k LEC data items cf. >100k LEC data items (attachments 8 & 13)
i.e. not due to HEC events

Another set of screenshots was taken around 18:00, and everything looks good.

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.

Thu Jun 13 21:06:44 2024, Robert Page, 16:00 to 00:00 shift on 13/6/2024 26x
|
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.

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:

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.
