Subject*:

14.37 Detector bias & leakage current OK - attachment 1
  
      FEE64 temperatures OK - attachment 2

WR timestamps - attachment 3
       aida06 out of sync

global clock status - attachment 4
       aida06 fails

ADC calibration - attachment 5
       all fail - probably due to ASIC synchronise *after* ADC calibration

WR decoder & FPGA TS status - attachments 6-7 
       aida06 status 0xd

DAQ run control - attachment 8
       aida06 undefined => aida06 has rebooted

Merger & Tape Server - attachments 9-10
       merger, tape server and data transfer have stopped

See https://elog.ph.ed.ac.uk/DESPEC/691
       aidao06 system console - aida06 rebooted sometime yesterday

*** Recovery

For FEE64 aida06 *only*

DAQ reset
DAQ setup

For all FEE64s

DAQ stop
Restart merger, merger setup, merger go 
 Following two merger restart cycles all FEE64s stopped OK
Recovery complete

All system wide checks OK

Disable data transfer, DAQ go

per FEE64 rate spectra = attachment 11
        aida04 high rates

per FEE64 1.8.W spectra - 20us FSR - attachments 12-13

DAQ stop, enable data transfer, DAQ go

Merger and server consoles - attachment 14
        merger and tape server (no storage mode) running OK but no data transfer to MBS server

WR timestamps OK - attachment 15

ADC and DISC data item stats - attachment 16-17
        aida04 & aida16 high rates - all others appear to be OK
        ASIC check load for all aida16 ASICs changes rate from c. 420k to 0 
        ASIC check load for all aida04 ASICs changes rate from c. 200k to c. 120k

18.00 No data transfer to MBS - nothing useful being donme at the moment - will place system in safe state

DAQ stop
      Detector bias OFF
      FEE64 power OFF
