|
21:35 (NH) - A few merger timestamp errors were appearing - Decided to powercycle all FEE64s, all checks OK.
No Screenshot due to forgetting before I closed merger
FEEs were often not stopping properly and needing merger reset as well.

Wed Nov 13 15:38:20 2019, NH, [HowTo] MBS for AIDA (Nov 19)
|
For MBS integration AIDA forwards its data to an MBS Foreign Data Receiver (FDR), currently the PC assigned for this task is x86l-94.
To start the MBS system do the following:

10:10 moved HV cables from 11 and 12 to 10 and 9 - all detectors biased in same configuration
lowered slow comparator threshold to 0xa

Tue Nov 12 14:10:18 2019, NH, OH, CA, Aida10 Unusual Pulser Peak  
|
aida10 (no alpha rate recorded) has a strange pulser peak - looks like double peak?
Pulser terminator checked and OK...
All others "OK" but noise quite bad (see previous entry) |
Wed Nov 13 01:54:00 2019, TD, Aida10 Unusual Pulser Peak
|
Double peaking normally indicates periodic baseline variations with period comparable to shaping time

Rates in all FEEs much higher than before - waveform shows very noisy in all systems. - attachment 1
Good event statistics - attachment 2

|
All 12 FEEs have valid WR Timestamps
Had to powercycle aida09 once as before raw readout was displaying upper 12 bits of WR timestamp as 0. Unsure of other method.

Mon Nov 4 13:17:12 2019, NH, Report: aida10 database corruption 
|
Often aida10 database seems to get corrupted (ASIC values are all 0xad)
Unsure why it's only aida10, might be related to weird alpha rate behaviour at the moment.

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 ? |
Tue Nov 5 10:32:21 2019, NH PJCS, Report: aida10 database corruption
|
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.

Tue Nov 5 11:15:41 2019, NH PJCS, Report: aida10 database corruption
|
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 |
Mon Nov 4 08:48:18 2019, NH, Alpha Status 04.11.2019    
|
Alpha run has been running over the weekend. Stats looking positive with notable exception that aida10 is not sending much data. Will attempt a powercycle.
Temperatures and Leakage Currents very good to excellent
Noted that the slow rate of aida10 seems to be slowing down the rate data is sent to tape - perhaps being buffered until an ADC event arrives? |
