ADC offset calculation using data from pulser walkthrough runs, see:

Attachment 1,2: excel and text file with tabulated ADC offset values.
Attachment 3,4: 2D histogram pulser amplitute vs channel number (with gain matching applied) for validating the
calculation.

Note: Channel with ADC offset=0 means ADC offset could not be calculated properly due to poor resolution/low
statistic

      Found that pulser induces counts in some HEC (nnaida20, 14 in particular). See attachment 15. Pulser off
removes these events completely.
      These events could be mistaken for implantation events during data acquisition.
      Increasing the fast comparator threshold HEC from 2 -> 3 suppresses the events. Increasing the threshold
to 4 does not appear to have further effects.
      Even with the increased threshold some HEC (e.g. 1.0H) still see the pulser. See attachment 16 (fast
comparator threshold HEC was 0x3).
      Checked data is synchronised in file R32_33

I have tarred and zipped all 24 logs and shipped them back to the UK. Now I can browse through them.

Studying the "panics" :=

       nnaida17 has one which is an NFS mount failure.

       nnaida20 and 22 have one each which are "Starting midas:  Page fault in user mode with in_atomic() = 1 mm = c61bf200" but with different values for the mm=.

I am studying the web to understand why this may occur in a particular program. Both occur at similar places  after "Starting midas".

There are reports of "Clock not locked. status = 0xc" during Setup Electronics which is a bit unusual. These occur in nnaida4, 17 and 22.

Also   "Clock not locked. status = 0xd"  in nnaida23,17,3,19,6,5,14,7,9. Further investigation to understand all these.

The bit allocation of the Clock Status word is:- 

Bit 0 : Lock Detect bit from LMK03200 #1

Bit 1 : Lock Detect bit from LMK03200 #2

Bit 2 : Lock detect from the internal DCM for the mux clock.

Bit 3: iDelay ready signal

The LMK03200  are the two PLLs which are connected to the 50MHz input clock. The clock setup in the log directly before the error report for nnaiad17 had reported correctly setup and the ADCs had calibrated, these rely on a stable 50MHz from the LMK03200s.

I have also spotted some diagnostic information about the waveform readout that is useful.

Just a reminder..... when power cycling the equipment please leave the power off for at least 10 seconds to allow all the capacitors in the supply chain to discharge.

Also note that the console monitor window in the Pi can be used to check that all FEE64s have "finished" the power-on sequence by using the "parse" button.

Since it doesn't use the DAQ software it won't lock-up and it will give an indication of progress.

Álvaro Tolosa Delgado reports observation of c. 1s 'oscillations' in implant-decay time spectra - see below

Hello

The worst cases (oscillations in decay-curve) are:

-->R23_91_115

--> R25_142_149

Other bad cases:

--> R23_44_70

Cheers!

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.

Offline analysis of AIDA data files R25_12 to R25_22 using MIDASsort

Note

- no calibration (raw ADC data only)
- no thresholds 
- no clustering
- events delimited by > 2us time difference between successive ADC data words 
- HEC = high energy channel = 20GeV FSR range for high energy implants
- LEC = low energy channel = 20MeV FSR range for decays (and pulser)

18.55 Julabo FL11006 recirculating chiller refilled to "H" marker of the filling level indicator.

      See http://www2.ph.ed.ac.uk/~td/AIDA/Information/Julabo%20FL11006.pdf
      
      To refill from 60% L-H to 100% L-H required c. 4 litres of water.
      Following refill there is a trickle of water from the overflow connector which is being 
      collected by hose and bucket - this flow should cease when the fluid level falls below
      the overflow level.
