(directory aidas1:/MIDAS/DB/EXPERIMENTS/AIDA/2015Feb23-12.11.40)
nnaida 1-2, 5-6, 9-10, 13-14 positive input ( front p+n junction strips )
nnaida 3-4, 7-8, 11-12, 15-16 negative input ( back n+n ohmic strips )
Standard ASIC configurations except
- shaping time 0xb (6,5us)
- peaking time 0x8 (16us)
- slow comparator 0x10 (~160keV)
- fast comparator (LEC/MEC) 0xff
- fast comparator (HEC) 0xff
nnaida 1-2, 5-6, 9-10, 13-14 negative input ( AIDA ASIC preamp output inverts input,
i.e. preamp with positive input produces negative input for sampling ADC )
nnaida 3-4, 7-8, 11-12, 15-16 positive input
Standard Waveform configurations except
- threshold 1000
- pre-trigger 0x100
- all channels disabled
2015Feb23-12.11.40 is now the default configuration file
Note: The directory (Data Base Key) which will contain the saved settings is created uid: npg, gid: npgstaff, perms 755.
However, its contents are written uid: nfsnobody, gid nfsnobody, perms 777. The default directory (Data Base Key) permissions
do not work - it is necessary to change the directory (Data Base Key) to perms 777 after its creation and before saving the
individual FEE64 configuration directories/files to it.

Concerning nnaida7 and the failure of calibration..... have you tried to calibrate it using the FADC Align & Control ?
If it still fails then there is a question about the quality of the clock signal being received by this module.
I will log through and look at the console log for any anomolies but please try and calibrate.
Let me know if you wish me to take remote control. |

Yes - there have been multiple attempts to re-calibrate nnaida7 ADCs
Note *all* ADCs were calibrated before the most recent FEE64 power cycle.
It is not unusual for ~1-3 FEE64s to fail ADC calibration tests following
a power cycle - there is no obvious pattern to which ADCs fail or which (if
any) will be successfully re-calibrated. |

The putty window for USB2 had frozen with a 1 in the voltage set as shown in attachment 1
The window was no longer updating.
When regaining the window the voltage limit was applied and the detector
began to ramp down
The set voltage was reset to 100V and bias was regained.
Total time with less than 100V was around 30sec

TD, AEV & CG | Monday 16th Feb progress | 16/02/2015
1500: AIDA moved into operational position.
Water cooling circuit visually checked, fittings, etc for loose fittings/snags/kinks. No problems
Julabo FL11006 chiller moved into position with mains transformer, filled and turned on without problem (small leak from rear overflow, due to overfilling).
Took roughly 2 ~30L water containers to fill reservoir.
Brief leak at connection between back of chiller and yellow hose, bolt tightened and it stopped.
Having been turned on and loop filled, reservoir at ~50% full. Pressure ~10 psi.
No leaks observed in main coolant loop.
When standing downstream of AIDA RH flow gauge blurred due to high rotational speed, LH flow gauge rotating at ~1 rev/s.
Two FEE modules closest to centre in each block checked for power cabling, TS distribution and network cables. All ok.
MACBs front panel cabling checked, no obvious problems. TS distribution tree in order.
Power on for NIM bins and fan tray, network switches and Raspberry Pi. Not yet for the FEE module PSUs.
1 corner of each new USB power supply damaged in transit.
Fuses changed from 10A -> 16A in each PSU. Old 10A fuses taped to back of each module.
1730: Turned on nnaida1-16. Temperatures stable. All on firmware version 0xa4ed006.
Input pulser into all FEE cards. All FEEs bar nnaida5 well-behaving. nnaida12 has several missing channels.
Typical pulser peak width for -ve input modules was ~14ch FWHM with shaping time of 1us.
Typical pulser peak width for +ve input modules was ~27ch FWHM with shaping time of 1us.
Changing shaping time of nnaida10 from 1->2.5us reduced FWHM from 27ch to 23ch.
