|
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)

Wed Jan 18 13:40:33 2023, PJCS TD, MACB settings with either Emulator or VITAR
|
When using the VETAR connected to the HDMI port of the root MACB the settings for all the MACB in the system 0x3.
This setting takes the Clock and Data line from the input HDMI and outputs it via teh HDMI output ports.
When using the Emulator connected via the SMA connectors on the back of the root MACB then the setting for the root MACB |

Wed Sep 14 19:07:07 2022, PJCS, INFO : Three Merger Statistics explained
|
There are three Merger statistics that can be used to better understand how the data flow through the Merger system is proceeding.
Two are from the Link task and one is from the Merger.They are all "No data buffers avaliable" with #1, #2, #3 at the end.
#1: This is incremented when the Link task has a data item to put in the queue for the Merge process but there is no room. |

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 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

|
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

Wed Jun 29 10:48:26 2022, NH, OH, AIDA Dismounted
|
All detectors removed from single and triple AIDA snouts
Empty snouts *and* DSSDs (in boxes) stored in NH office |
|
Tue Jun 28 10:11:35 2022, OH, NH, MIDAS Data Aq V10
|
11:11 Rebooted FEEs and changed aidacommon in /MIDAS/linux-ppc_4xx/startup to point to the new V10 DataAq that Patrick produced
When using V9 the Merger statistics reported WR items at twice the rate of ADC data items.
i.e for ever data item we were sending and info code 4 and info code 5 item sending 192 bits of data vs 64 for just the data word

16:00 Took over the shift from OH no beam yet.
18:00 Still no beam yet.
Statistics, Temperature, Current are checked and attached 1-3 |

|
07:45 Spoke to David and the beam has been gone since about 05:30
Reason for the loss of beam is a vacuum issue before the FRS
They are waiting for the experts

Sun Jun 26 23:04:30 2022, Marc, new shift - Monday 27 June 0:00 to 8:00 12x
|
0:00 Experiment continues to run smoothly. AIDA DAQ has been rather stable. Leakage current has gone up for the past two days in both DSSDs (combination
of high-Z and high-intensity beam and external high temperature).
Stats & Temperatures (VIRTEX,PSU, ASICs) all ok. |
