 Fri Apr 9 16:45:29 2021, NH, HA. GA, GZ, OH, TD, AIDA Noise 6x
|
AIDA snout was reconnected and we saw originally a very good reduction in noise from S452 (fig 1)
Occasional bursts of increased rates were noticed, perhaps related to works in S4.

A spreadsheet of ambient conditions and water temperature in S4 for AIDA.
Will show the distance to danger points (interlock shutdown and condensation on the pipes) |

Tue Jun 4 09:19:10 2019, NH, AIDA Interlock
|
Currently AIDA's interlock is off (no lights) and hence AIDA cannot be powered on. Under investigation - power supply has been replugged but seems
ok.
Update: It seems the interlock is correctly stopping AIDA from being powered on due to high humidity on the cooling lines. Am currently trying |

Remove all DSSD ribbon cable braid ground from FEE64s to check n+n ground loops
Removing all on n+n side only and test resistance to ground: 4, 6 and 8 show continuity to ground, 2 shows no connection (braid ring terminal to copper |

Wed Apr 10 12:33:58 2019, NH VP, AIDA Firmware Update
|
All AIDA modules have been updated to a new firmware 0xd330701 which should fix the merger issues.
A new GSI WR timestamp page has been added to MIDAS - the SYNC rollover is suggested to be 0xe for now.
(VP is working on lowering the rate of WR SYNC infowords) |

Some plots of AIDA dead time (From PAUSE/RESUME data items) against time.
The histograms are binned in intervals of 100 ms, with the blue bars corresponding to dead time in the FEE - the y-value is the percent of the 100ms interval |

If necessary they can be removed from AIDA HDDs for space.
There are also spare HDDs that can (and should) be swapped for the current ones

|
AIDA PC crashe completely at ~3:30am CET.
Tom was called and he Restarted the AIDA system at ~4am with Run 52.
Not sure what cause the crash but AnyDesk remote connection was suddenly lost and once reconnected all Terminal sessions were gone. |
