08:00 OH Takes over for CA
Thresholds 0xc for p+n and 0x19 for n+n ASICs 1-3 and 0x64 for n+nASIC4
PULSER SETTINGS
---------------------------
Pulse is ON
Positive Tail Pulse
Trigger Source is Internal Clock
Trigger Threshold is 3.5
Amplitude : 2.0 Volts
Rep Rate : 2.0 hZ
Delay : 250.0 ns
Fall Time : 1 ms
Attenuation : 1
Display is : Volts
Equivalent keV is : 200.0
Ramp Start at 0.01 Volts
Ramp Stop at 9.99 Volts
Ramp Start at 1.0 keV
Ramp Stop at 999.0 keV
Ramp Time is 60 seconds
# Ramp Cycles is 1
Max average dead time in R14_586 3.2% which is 9.6% on spill
Stable from yesterday
10:02 System wide checks. All ok expect WR
Base Current Difference
aida05 fault 0x500 : 0x554 : 84
White Rabbit error counter test result: Passed 15, Failed 1
Understand the status reports as follows:-
Status bit 3 : White Rabbit decoder detected an error in the received data
Status bit 2 : Firmware registered WR error, no reload of Timestamp
Status bit 0 : White Rabbit decoder reports uncertain of Timestamp information from WR
Statistics - Attachment 1
Temp - attachment 2
Bias and leakage currents ok - Attachment 3
11:17 A new run was started as the microspill has been changed. I believe to optimise FRS deadtime.
11:45 They are still working on it
12:05 Beam off for a bit while they optimise spill
12:15 System wide checks ok expect WR
Base Current Difference
aida05 fault 0x500 : 0x567 : 103
White Rabbit error counter test result: Passed 15, Failed 1
Understand the status reports as follows:-
Status bit 3 : White Rabbit decoder detected an error in the received data
Status bit 2 : Firmware registered WR error, no reload of Timestamp
Status bit 0 : White Rabbit decoder reports uncertain of Timestamp information from WR
Statistics - Attachment 4
Temp - Attachment 5
Bias - Attachment 6
13:11 Magda has said that the changes to the spill structure only gained them a few percent in dead time
Further changes could be done, but would take at least two hours
13:19 Dead time following the current spill changes
