in spill rates to MBS up 30+Mb/s, 2.5M data item/s merged
DSSSD bias & leakage current - attachment 28
c. few hundred nA step in leakage current
analysis of data file R20_33 - attachment 29
max deadtime 18% (aida08)
no timewarps
HEC data item rate 4.1kHz (c. 2.4x previous FRS setting)
Correcting for spill cycle => 5.9kHz in spill (online analysis shows no HEC events observed outside spill)
assume typical HEC event multiplicity = 3 => implant rate ~ 2.0kHz in spill or 6800 implants per spill
SC42 L/R currently report c. 4.5kHz
Note that we currently see a higher fraction of events in DSSSD#2 cf. previous setting so multiplicity assumption may be low
If we assume multipicity = 6 => implant rate ~ 1.0kHz in spill or 3200 implants per spill
we are probably somewhere in between

First checks of shift. All looks ok.
Screenshot of HV, temps, rates, Merger attached. Attachments 1-4.
Screenshots of all spectrum Layout IDs taken before zeroing at 16.35. (Attachments 5-12)
checks at 16.00 - merger has crashed - aida01 dropped out - Tom tried to stop DAQ but got an error. Restart servers restarted at 16.09
Reset 01, restarted DAQ, and restarted as R16.
16.15 Data seems to be collected but spectra not being incremented in aida01. Timestamps look to be out of sync. Tom restarting aida01 again.
Did not fix, power cycle all FEEs - all spectra reset. aida3,6,11,12,14,15 wont calibrate adcs so wont have waveforms
RUN17 STARTED 16.51|
HV, temps, rates, Merger looks ok 17.00. Plots saved as attachments 13-16.
20.47, all looks ok - see attachment 17-20. Rates are higher in attachment 20 than in attachment 2 from start of shift
21.59 aida02 (link aida1) stopped taking data and dropped out of the merger (see attachment 21). Came back to life after about 15 miutes. Tom logged in remotely to investigate. Seems to be ok. see attachment 22 for timestamps
22.48 - things apear ok. (Attachments 23-26) |

Attachment 1 - per DSSSD LEC e_p versus e_n (20keV/channel)
Attachment 2 - per DSSSD HEC m_p versus m_n
Attachment 3 - per DSSSD HEC x versus y (I really do need to sort out the mapping!)
Attachment 4 - per DSSSD HEC e_p versus e_n (20MeV/channel)
Attachment 5 - per DSSSD per pixel HEC-HEC time (4.096us/channel)
Attachment 6 - per DSSSD implant/decay event rates (262.144us/channel)
showing beam spill cycle

TD | Report: aida04 stops producing data |
09.14 aida04 stopped producing data - system console output - attachment 1
It is not clear (to me at least) whether the cause is radiation-induced single event upsets or
the start/stop of LN2 fills.
Nor is it clear why the FEE64 stops
- WR timestamp error (data link to Merger blocks)
- AIDAExecV10 fails
- ?
rebooted aida04
DAQ RESET/SETUP etc cycle for all FEE64s
10.03 successful restart

large variation in rates beam off/on
c. 10.30 beam off (for new FRS setting?)
11.25 analysis of data files R14_19 (beam ON) and R15_24 (beam OFF) - attachments 28-29
For beam ON max deadtime c. 11% (aida04), beam OFF max deadtime c. 0.1% (aida04)
Zero timewarps observed
Notice large # of PAUSE/RESUME data items for aida03 & aida04 presumably due to additional overhead of processing the time machine scalers
12.35 Beam off
DSSSD bias & leakage current OK - attachment 30
Can observe beam spill structure in DSSSD leakage currents - now slowly recovering with beam off
