AIDA02 and AIDA06 gave zero attachment 1. After connecting with Tom to fix it, now it works.

Statistics  attachment 4

17:39

Most of AIDA0 gave zero. I followed the instructions that Tom gave me to fix it, and now they work.

23:19 Flange removed. Starting to take beam.

1) Select 'No Storage' [workspace 3, display 1, browser tab 'TapeServer']
    If already in 'No Storage' mode please ignore this step

2) STOP DAQ [workspace 2, display 1, browser tab 'Run Control']
   all FEE64s should change status from 'going' to 'stopped' *except* whichever FEE64(s) have a problem - typically their status is 'going' or 'error'

3) Restart Merger by selecting the Merger icon [workspace 3, display 2]
    terminal window showing the startup will popup

4) Setup Merger by selecting 'SETUP' [workspace 3, display 1, browser tab 'NewMerger Control']

5) Start Merger by selecting 'GO' [workspace 3, display 1, browser tab 'NewMerger Control']
     all data links will be inactive (red)

6) Start DAQ by selecting 'GO' [workspace 2, display 1, browser tab 'Run Control']
     check that DAQ is *actually* going - if not repeat 'GO'

7) Check data is being transferred to Merger and TapeServer

    Select 'Reload' [workspace 3, display 1, browser tab 'NewMerger Control']
     you should see a non-zero 'current merged data rate' and all links should show as green at least some of the time (requires observation over several reloads)

    Select 'Reload' [workspace 3, display 1, browser tab 'TapeServer']
     you should see 'Blocks written' and 'kb written' counters increase

8) Check AIDA data is being forwarded from the TapeServer to MBS [workspace 3, display 2, command terminal]

9) Unselect 'No Storage' [workspace 3, display 1, browser tab 'TapeServer']
    If already in 'No Storage' mode at the start of this procedure please ignore this step


   If you continue to have problems, please request expert assistance.

We are trying to bias each system on its own and in sequence biasing each other detector system to see the interdependence.
 

HV OK. TEMP OK. Attachment 1 &2.

9.43 bPlast unbiased, BB7 unbiased. Attachments 3-6 is the noise situation with only AIDA biased (bPlast was biased but turned off after AIDA was biased.)

10/16 FEEs < 20k noise. Max noise is 250k. Downstream AIDA appears to be seeing additional noise since S100.

11:21 Returning after an hour the noise has increased significantly in many channels. Scale changed to 10000 in histograms, it appears that the problem is from a couple hot channels.

11:41 'Power' cycled AIDA turned off. bPlast turned on, on its own, then BB7. bPlast doesn't seem to notice anything.

12:21 bPlast and BB7 on. AIDA ON. Rates and histograms given by attachment 7-8. More FEEs noisy, but same level as 11:21. There appears to be the same noisy channel in all of the FEEs (?) Some grounding not properly accounted for, or a wire touching somewhere (?)

13:55h: AIDA & BB7 on. Rates and histograms given in attachments 9-10. Same level as bplast & AIDA on. Same noisy channels in FEEs. According to Nic, these correspond to the end of the ribbon cables & is normal.

13:59 AIDA, bPlast & BB7 on before lunch. Same levels of noise as in previous combinations (attachments 11-12).

So it seems we can run with the three sub-systems biased simultaneously.

DEGAS Array over Snout again

Situation similar to yesterday, most p+n rates good

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.

AIDA and the Snout have been remounted in S4

I had a check of the AIDA connectors and all looked good, the kapton PCB connectors were sitting comfortably above the interstage and I saw no stressed/loose connectors.
Multimeter showed no continuity between snout or inter-stage and AIDA ground

We put a single layer of wide black tape inside the end-cap to improve the light seal and minimise reflections

After mounting the snout I managed to bias both DSSDs to 100 V with no issues. I had to raise the DSSD#1 (Ch0) limit to 40 uA because it rises quite high during ramp up (then settles).

It is very hot in S4 (28 C) and the roof is closed for high-radiation experiments, so I expect it to get hotter. DSSD leakage currents were similar to before (20 and 15 uA)

There is also the new Temp and Humidity monitor, which you can view on AnyDesk at 192.168.11.119 (I think), there is a firefox window open already

Status before dismount

          DSSSD#2 119.95 V @ 11.212 uA

          Leakage currents slightly elevated from Monday.

S4 temperature at 26 °C.

14:30 Detectors being debiased. All relay channels turned off. Voltages and currents of both DSSSDs to 0.

Plan:

- Dismount snout.

- Open up and remove BB7 and Upstream bPlast - leave AIDA 1 and 2 in place if possible.
