 Sun Jun 19 19:55:20 2022, NH, aida03 and aida04 
|
aida03 and aida04 seem to stop sending data quickly
stopping DAQ + merger and restarting got them resending data, but quickly stopped again
|

Experiment over
10:37 - Stop DAQ & Tape

Tue Aug 30 13:48:32 2022, NH, AIDA Single Switch Configuration
|
The second switch was moved back to CARME so AIDA has been configured back to using a single switch
aida02/aida04/aida06/aida08 updated back to first switch as per https://elog.ph.ed.ac.uk/DESPEC/433

Thu Sep 8 12:31:25 2022, NH, Retrying AIDA DataAcq v10
|
Startup AIDA with ribbon cable connected to aida03 and aida07 for noise
Setup and run with waveforms enabled. Discriminators ADC power etc as default
|
|
Thu Sep 8 12:37:18 2022, NH, Proxy Port Changed
|
The proxy in Firefox, Yum and AnyDesk has been changed as the old wasn't working
proxy.gsi.de port 3128 is now in use |
|
Thu Oct 6 16:51:49 2022, NH, Oscilloscope analysis 24x
|
Investigating AIDA noise with a TA041 differential probe and oscilloscope
AC Mains (DESPEC platform AC, L-N)
|
|
Fri Dec 16 14:02:12 2022, NH, AIDA System off for christmas break
|
| The AIDA NIM crate, pis and workstation have been powered off for the Christmas break and will not be accessible |
|
Mon Aug 28 12:47:56 2023, NH, Power Failure 24.08.2023
|
There was a power failure in the morning of 24.08.2023 in the Rhein-Main area affecting GSI
The Aida workstation (aida-3) has been restarted, it is unknown if the Pis in S4 rebooted as well (there is a UPS)
|
|
Thu Aug 31 15:24:56 2023, NH, New AIDA MBS PC
|
The AIDA MBS FDR will be x86l-119 from now on, not x86l-94
the MBS relay and startup scripts will be changed for this |
|
Sun Mar 10 17:08:12 2024, NH, AIDA FEE Layout + Cabling Plan for S100
|
Proposed FEE numbering and wiring plan for upcoming experiment S100 (2x Wide DSSSDs)
Image designed in draw.io, source attached
|
|
Fri Mar 15 16:29:57 2024, NH, Leakage currents
|
The behaviour of the DSSSD leakage current at low voltages and during biases is unusual and varies depending on how the adapter boards are connected
To summarise the behaviour I have observed
|
|
Mon Mar 18 18:04:43 2024, NH, Preparation for pre-s100 dry run (and test beam???)
|
In preparation for the dry run the following *temporary* changes to the FEE numbering have been prepared
These should be reverted after the dry run to ensure cable->fee agreement again
|
|
Tue Mar 19 10:17:30 2024, NH, Dry Run 2024 - 19th March 24
|
AIDA has 8 FEEs and 1 DSSSD
Aida08 (HDMI#12) had no WR again, I moved it to a different MACB and now it gets WR
|
|
Wed Mar 20 12:22:27 2024, NH, Wed Mar 20 9x
|
Turn on AIDA for Dry Run demonstrations and so on
All system wide checks, temp, bias OK
Noise situation is dreadful (but has not been optimised). Deterioriation since first mounted, suspect cabling issues with bPlast and BB7. |
|
Wed Mar 20 17:02:53 2024, NH, /dev/sdd
|
The following messages are in the system log very often:
Mar 20 18:00:56 aidas-gsi smartd[1076]: Device: /dev/sdd [SAT], 2224 Currently unreadable (pending) sectors
|
|
Wed Apr 3 12:09:47 2024, NH, Report - aida06 frequently fails to boot first time (PHY error)
|
When booting up AIDA aida06 usually crashes the first time, it fails to get IP from DHCP
After 180 seconds it reboots and seems to connect fine
Log file attached, key part (to me) is this: |
|
Wed Apr 3 12:42:57 2024, NH, Report aida02 WR errors
|
The WR error counter for aida02 seems to consantly rise
Tried reseating cable on both ends, no change
However clock status passed, aida02 has a correct WR timestamp and no FIFO/PLL errors seen |
|
Wed Apr 3 13:02:19 2024, NH, Merger for 16 FEEs
|
Changed /MIDAS/Linux/startup/NewMerger
Change parameters -i and -l in master64 to 16 for 16 FEEs
|
|
Tue Jun 4 15:40:32 2024, NH, Tues 4 Jun
|
DEGAS Array over Snout again
Situation similar to yesterday, most p+n rates good |
|
Wed Oct 29 13:01:08 2025, NH, Update of AnyDesk
|
AnyDesk was updated to the latest version that supports CentOS 7 (EOL OS)
First the YUM repositories were migrated, as the original address was offline due to EOL
