11.00 Restore power to AIDA following Saturday's shutdoen in preparation for the planned maintenance
outage on Sunday.
Restart Julabo FL11006 chiller - set point +20 deg C
Restart AIDA
Temperature +24.3 deg C, DP +15.2 deg C, RH 57.5%
DSSSD #1-6 bias - see attachments 1-2
FEE64 temperatures - attachment 3
System-wide checks - see attachments 4-8
Note SYNC pulses received by *all* slave FEE64s = SYNC pulses sent by master FEE64 (nnaida6)
11.35 R6 starts
slow comparator 0x10
LEC/MEC fast comparator 0x10
All FEE64 discriminator masks -> 0x0
observe very high rates (~400-500kHz/FEE64) from majority ofp+n junction FEE64s
LEC/MEC fast comparator -> 0xff
18.45 DAQ running OK
No merger error messages since change of LEC/MEC fast comparator threshold -> 0xff
Offline analysis of R6_79 confirms that all FEE64s are synchronised
Added correlation trigger input
BNC PB-4 Pulser trigger output -> Ortec SCA + NIM output width 0.5us -> LeCroy 429A -> root MACB trigger
#4 input
21.05 R7 starts
Attachments 9-16 show FEE64 temperatures and results of each system-wide check.
Note the result of the Master Timestamp Control -> Check Clock Lock States
indicating clock state *not* locked
slow comparator 0x10
LEC/MEC fast comparator 0xff
All FEE64 discriminator masks -> 0x0 |
