Thu Feb 8 14:59:59 2024, JM, TD, Change p+n FEE64 settings
|
ASIC settings for the pn FEEs has been reset to the default aida settings. This was done to combat the observed dropping of several channels in pn only
FEE modules
following motors movement. This effect was also observed in 2022 in several pulser walkthroughs conducted pre and post detector movement. No dropped channels |

10:30 Found ADC#4 on aida 1 and 4 are suddenly noisy. See attach 1-2. Checkloaded multiple times - no effect.
Leakage current overnight was stable, but a clear transient can be observed yesterday around the times of the DSSD motion test. We did not observe
this in the cave looking at the CAEN module - it might have been too fast. |

|
To include alll 16 FEE modules in the NewMerger we edited the file /MIDAS/DB/EXPERIMENTS/MERGE/Options/carme-gsi from MERGE.LinksAvailable string 5 to
MERGE.LinksAvailable string 15
We also edited the file /MIDAS/Linux/startup/NewMerger from ./master64 -i 8 -l 16 -p 11001 & to ./master64 -i 16 -l 16 -p 11001 |

Thu Feb 1 10:04:11 2024, JM, CB, Shaping time testing 31x
|
Arrived at the control room to find we had lost connection to the power relay. We rebooted the nnrpi1 and re-connected according to the steps laid out
in elog 471 -> all okay
11:00 Restarted daq with no changes to the system from yesterday. Bias consistent with previous days. All pulser peaks are slightly improved |

Wed Jan 31 09:49:38 2024, JM, TD, Optimising - Wednesday 31 25x
|
Removed ground from DSSD #1 to the chamber and set MACBs so that timestamp is from the NIM WR emulator not the VME VETAR2.
Root MACB mode 0x3 -> 0xd - all other MACB modes 0x3 ( unchanged ).
No timestamps observed from the emulator. Re-set to take timestamps from the VETAR" unit -> all timestamps observed. |
