 Fri Oct 29 10:49:01 2021, OH, Noise tests - 28th October -29th October 24x
|
Plan for the day was to connect a mechanical ground to the FEEs connected to DSSD0 1, 2, 3, 4, 9, 10, 11 and 12
This was done by connecting thick copper cable to the mechanical ground wires on the AIDA frame (These ground wires are connected to the platform ground |

Wed Oct 27 15:12:50 2021, OH, NH, Noise tests - 27th October 6x
|
Began by installing the triple.
Only the upstream detector was connected to the FEEs the downstream detector cables were left loose. The two detectors are isotolated though.

Pulser was left on overnight with the bias filters on
First plot is FEE14 not FEE8

Mon Apr 15 09:23:43 2024, CC, JB, HMA, TD, Noise in AIDA when connecting BB7 13x
|
9:40 started up AIDA. TEMP OK. Noise condition same as Saturday. Attachments 1-3.
9:56 BB7 premaps connected but not powered. Attahcment 4.
10:20 BB7 Preamps powered. Attachment 5. |

Mon May 20 13:33:06 2019, NH, New Merger/MBS Test Runs 8x
|
New merger has been worked on by VP which fixes the timewarp issues and MBS integration.
Currently no WAVE capture is supported, VP will re-add WAVE histogramming for startup testing.

 Tue Aug 13 13:55:45 2019, NH, New Merger/MBS Test Runs 6x
|
AIDA Finally working again so can test VP's added WAVE histogramming mode.
Fig 1. Waveforms for FEE12 ASIC 1. Sample rate = 10, Threshold = 10500
n.b. lots of "blank" wave channels for unknown reason, all low-energy channels show pulser so it's not a DSSD signal problem? |

Wed Mar 18 18:02:37 2020, PJCS, New Firmware loaded in all FEE64s
|
Loaded new frimware into all 12 FEE64s in the system. IWR_Dec19_4.bin
Booted ok after power-cycle.
RESET/SETUP/GO all fine. |
|
Wed Nov 27 16:33:50 2019, NH, New Bias & Waveforms
|
HV core (-160 V) now attached to bottom 3 FEEs (with grounded kapton)
DSSDs bias OK, leakages unchanged
No appreciable change in waveforms |
|
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 |
|
Wed Dec 11 14:46:21 2024, TD, JB, CC, MP, Mounting of AIDA, bPlast and BB7 for test
|
Snout assembled for detector position and timing test.
The planned test is to use a BGO with a 22-Na source and the implantation stack to characterise the timing and position of back-to-back 511 keV
events (proxy for mock beta decay event). |
