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 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: |

Some additional checks
- check 'top hat' electrical isolators are correctly installed at each of the 4x mounting points of the AIDA snout assembly
- check snout is electrically isolated with respect to AIDA support assembly/stand, bPlas PCBs/cabling/ground/drain wires and BB7 |

The following messages are in the system log very often:

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. |

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

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
|
|
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
