 Tue Nov 5 10:02:45 2019, NH PJCS, Report: aida10 database corruption
|
This looks like the Options not the ASIC data. That will be in the CONTENTS file of the FEE64 named directory within the dated EXPERIMENT directory.
Looks like the latest is at /MIDAS/DB/EXPERIMENTS/AIDA/2019Oct31-13.24.23/aida10 ?
A quick look at this file and it looks normal , not all 0xad ? |

|
Hi, see the attached files in the original comment. I think the BACKUPCorrupt is quite old now.
The Options data gets corrupted and for example the ASIC folder gets set to 'undefined' which I think is why the ASIC data loads incorrectly.

|
If ypou now check the actual values in the aida10 Options screen are the correct ?
It can happen that corruptions once loaded are propagated when Options are generally saved.
Looking at the dates the files were modified does that make sense to you. It doesn't look as if the corrupted database was changed except |

Thu Oct 31 16:43:03 2019, NH CA TD, Merger & MBS Performance
|
Testing merger with 3 DSSDs connected, with thresholds of 10 (slow comparator), 2 (HEC) and 255 (fast discriminator)
Merger handling rate of 1.6 million events per second comfortably. Forwarding to MBS fine.

Fri Jan 25 12:33:03 2019, NH, aida-gsi Access
|
If you have a GSI account it should be possible to connect to aida-gsi remotely via the following
SSH into lx-pool.gsi.de with GSI Linux username/password (ssh username@lx-pool.gsi.de)
Then SSH into aida-gsi via ssh npg@aida-3 |

Wed Mar 20 15:35:10 2019, NH, AIDA Setup @ GSI
|
Currently
- 1 DSSD and Plastic is in the AIDA snout, which is not mounted
- The FEEs are offline due to a water supply issue, this will be repaired early 21/03/2019 |
|
Thu Mar 21 13:59:08 2019, NH, AIDA Water
|
The AIDA water system has been repaired and not leaking.
The interlock did not light immediately, but power cable reconnected to box and now it works.
|
|
Thu Mar 21 14:10:10 2019, NH, FEE Temperatures
|
All 12 FEEs powered up, and temperatures are OK.
Passed ASIC checks and system wide checks - now checking cabling and to mount snout. |
|
Fri Mar 22 13:32:55 2019, NH, AIDA Startup @ 22.03.2019
|
FEEs have been on this morning, temperatures attached
Leakage current attached
the DSSD is attached to the following AIDA modules: |
|
Fri Mar 22 13:47:32 2019, NH, Resolution Checks
|
Pulser widths of AIDA modules, resolution is fairly typical. AIDA09 still noisier than other DSSD channels.

Figure 2: Raw waves (AIDA01 did not calibrate, so AIDA02 used instead as "non DSSD module") |
|
Fri Mar 22 14:31:24 2019, NH, A few more setup notes I forgot
|
Extra FEE information:
HV braid (0 V) goes into FEE10 (beam left) with LK1 jumper
HV core (-160 V) goes into FEE09 (top) |
|
Fri Mar 22 15:44:20 2019, NH, End of 22.03.2019
|
End of the day - Detector unbiased and FEE64s turned off for the weekend as they won't be monitored.
Water will remain on. |
|
Mon Mar 25 14:44:33 2019, NH, Merger issues
|
Plastic electronics have now been installed.
Water is not leaking still.
FEE64s powered on at 15:00 to test MBS connection (fig1: temperatures) |
|
Tue Mar 26 14:59:30 2019, NH, 26.03.2019
|
Fig1: FEE temperatures from 26.03.2019 all OK
AIDA has been on today and merger setting fixed (see previous ELOG entry https://elog.ph.ed.ac.uk/DESPEC/36)
Still diagnosing issues with MBS (figure 2) but local data acquisition should be functional. |
|
Tue Apr 2 09:42:20 2019, NH, MBS Server setup
|
MBS is currently configured and accepting data:
x86l-94 : AIDA Foreign data receiver
x86l-4 : DESPEC Time sorter |
