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.

0) Please infrom the 'on shift' crew that you need to restart the AIDA DAQ

1) 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'

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

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

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

5)   Disable data transfer by selecting 'Data transfer Disable #1 all' [workspace 2, display 1, browser tab 'Run Control']

6) Start DAQ

    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 WR timestamps by selecting 'Collect all timestamps' [workspace 2, display 1, browser tab 'GSI White Rabbit Control']
     readout times will be displayed for each FEE64
     check that the readout times are monotonically increasing as you read down the list of readout times - if not, contact expert support

8) Stop DAQ 

    Start DAQ by selecting 'STOP' [workspace 2, display 1, browser tab 'Run Control']
     check that DAQ has *actually* stopped - if not repeat 'STOP

9) Enable data transfer to Merger and TapeServer and start DAQ

    Enable data transfer by selecting 'Enable data transfer Enable #1 All' [workspace 2, display 1, browser tab 'Run Control']

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

10) 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

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

12) Restart should now have been successfully completed. Please inform the 'on shift' crew' that AIDA is forwarding data.

    If not, please request expert assistance.

16.45 aida04 stopped producing data

      DAQ STOP (workspace 2, display 1, browser 'Run Control' tab)

       aida04 did not stop, all other FEE64s stopped

      restart Merger (workspace 3, display 2, select 'NewMerger' icon)

      SETUP Merger (workspace 3, display 1, browser 'NewMerger' tab)
      GO Merger (workspace 3, display 1, browser 'NewMerger' tab)

       aida04 now stops

      disable *all* #1 data transfer 

      DAQ GO (workspace 2, display 1, browser 'Run Control' tab)
      check WR timestamps OK (workspace 2, display 1, GSI WR Timestamp Control)

      DAQ STOP (workspace 2, display 1, browser 'Run Control' tab)
      enable *all* #1 data transfer
      DAQ GO (workspace 2, display 1, browser 'Run Control' tab)


      No reboot or power cycle required. Just clear the Merger data links, restart DAQ.
      

16:00 aida04 not producing data

          power cycle all FEE64s to recover DAQ

16.20 analysis data file R21_668

         max deadtime 17% (aida04), 9% (aida02), 2% (aida06) all others < 1%

         no timewarps

         HEC data item rate 1.9kHz

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.

14.45 analysis data file R21_500 - attachment 36

         max deadtime 22% (aida11), 16% (aida04), 7% (aida02), 6% (aida08), 6% (aida06) , all others < 1%

         no timewarps

         HEC data item rate 2.7kHz

Encore un matin, un matin pour ..... a shift !!!ramping up again ! S4 temperature not really going down either: 25C

0:40 AIDA04 is down. I informed the DAQ shift crew and attempting to restart AIDA04.

After rebooting AIDA04 all seemed going until I reached the merger check. No data was being merged.

I realise then that AIDA01 data transfer was not active. I did not spot it when I enabled the data transfer for all.

I stopped the daq and rebooted AIDA01 following all the instructions in the ELOG and this worked.

We are now back in business with AIDA back in main DAQ at  01:40

01:45 full checks:

           Bias: AIDA-Graphana - Attachment 1

               Leakage current ramping up again ! S4 temperaturenot really going down either: 25C

      FEE64 temperatures OK - attachment 2

03:00 full checks

          No change to be highlighted. All pretty much the same as during previous full checks.

05:00 full checks

Expt still running very smoothly.

           Bias: AIDA-Graphana - Attachment 7-8

               Leakage current going down slightly

07:15 all running smoothly.

07:20 Spoke too fast AIDA DAQ is down. DAQ shift crew informed.

07:40: AIDA10 was rebooted successfully and AIDA is now back in the main DAQ.

14:50 Checks

Leakage current  is 20.021 and HV status is Max Voltages ! Is it normal ? - attachments 1

It is quite warm at GSI today and this may be a temperature effect. Hopefully will go down latter in the day (Marc). Any way let's kep an eye it. The current threshold is set to 30uA.

18:15 Checks

Everything appears to be going smoothly 

Grafana - DSSSD bias  and leakage current - attachments 2 and 3

FEE64 temperatures  - It appears okay, nothing strange , attachment 4

ADC data item stats - attachment 5

Per FEE64 Rate spectra - attachment 6

 ucesb - attachment 7

18:16

The temperature for aida07 gave us No response - attachment 9 , I had emailed Tom to fix.

18:20  it came back to work normally

............................

20:00 Checks

Nothing new to report. All is well.

20:33 Aida02 showed as not reading - attachment 10

20:34 it resumed reading and returned to normal operation.

21:08 Aida02 was  not reading - attachment 11 , had to emailed Tom to fix it .

The shift crew have restarted ucesb and AIDA  is now showing OK - attachment 12

so Tom guess the problem really was at their end . They may still have a problem with the FRS DAQ.

ADC data item stats and Merger etc  appear to be going smoothly - attachments 13 and 14

...........................................

22:00 Checks

Still running smoothly.

DSSD bias and  leakage current - ok

5:20 AIDA 4 stop counting in the last 20 min. I informed the main DAQ and they started a new run without AIDA.

        DAQ restarted OK. Main DAQ informed.

This appeared in the system log:

Apr 26 16:30:51 aidas-gsi smartd[1076]: Device: /dev/sda [SAT], 1 Currently unreadable (pending) sectors

These messages seem to appear sporadically.

18:10 Link 3 is giving rates of zero (see attachment 3). Is this normal?

18:15 daq error on ucesb (attachment 4). Zero rate through event builder. Emailed Nic & can see he's now on Zoom.

aida07 rebooted itself, but WR out of sequence still
manually reboot aida07, still out of sequence
do full powercycle of aida... now all FEEs are in sequence again. Resume running to disk and alert DESPEC shifters

Thanks Nic!

22:14 AIDA DSSD 2 HV status = 99 on grafana (attachment 6)

22:43 Noticed that aida02 ASIC temperature reading is now 0.00 instead of 511(!) that it was previously - see attachment 2 in #608. It was similarly high earlier in this shift too.

Occasionally, one (sometimes more) FEE64(s) will stop producing data whilst the DAQ is running *and* data is being transferred to the Merger and TapeServer.

Typical symptoms are:

- no data in Rate spectrum [workspace 2, display 1, browser tab 'Spectrum Browser']
- zero rate in 'ADC data item' statistics [workspace 2, display 1, browser tab 'Statistics']
- Merger data link inactive [workspace 3, display 1, browser tab 'NewMerger Control']
   active data links are green, inactive links are red
   N.B. data links are numbered from 0 to n-1, FEE64s are numbered from 1 to n

0) Please infrom the 'on shift' crew that you need to restart the AIDA DAQ

1) 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'

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

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

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

5) Reboot problem FEE64s
   Launch a command terminal and telnet to the problem FEE64 for example

    telnet aida04

   Enter user 'root' and enter password. When logged in reboot the FEE64 using the command

    reboot

6) Monitor boot using server system log [workspace 1, display 2, browser tab 'terminal']
    you should see two messages showing the FEE64 mounting filesystems
    wait c. three minutes for boot to complete

7) Restart DAQ

   Select DAQ status 'Update' [workspace 2, display 1, browser tab 'Run Control']
   Select DAQ status 'RESET' [workspace 2, display 1, browser tab 'Run Control']

     check that DAQ is *actually* going - if not repeat 'GO'

12) Check WR timestamps by selecting 'Collect all timestamps' [workspace 2, display 1, browser tab 'GSI White Rabbit Control']
     readout times will be displayed for each FEE64
     check that the readout times are monotonically increasing as you read down the list of readout times - if not, contact expert support

13) Stop DAQ 

    Start DAQ by selecting 'STOP' [workspace 2, display 1, browser tab 'Run Control']
     check that DAQ has *actually* stopped - if not repeat 'STOP

14) Enable data transfer to Merger and TapeServer and start DAQ

    Enable data transfer by selecting 'Enable data transfer Enable #1 All' [workspace 2, display 1, browser tab 'Run Control']

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

15) 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

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

17) Restart should now have been successfully completed. Please inform the 'on shift' crew' that AIDA is forwarding data.

    If not, please request expert assistance.

      DSSSD bias & leakage current - attachment 28
       c. few hundred nA step in leakage current 

      analysis of data file R20_33 - attachment 29
      max deadtime 18% (aida08)
      no timewarps
      HEC data item rate 4.1kHz (c. 2.4x previous FRS setting)

      Correcting for spill cycle => 5.9kHz in spill (online analysis shows no HEC events observed outside spill)
      assume typical HEC event multiplicity = 3 => implant rate ~ 2.0kHz in spill or 6800 implants per spill
      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
