12.45 Rly16 'Sequence ALL On' operational 15.20 Startup remote control of CAEN N1419 4-ch HV modules DSSSD #1-7 leakage currents OK - see attachments 1-2 Ambient temperature +24.8 deg C 15.35 Plot Temperature appears to plot the first 15,000 (or so) temperature readings and not the *most recent* 15,000 (or so) readings. See attachment 3. There is no way to change the time window for the temperature plot As a workaround, empty file using the command cp /dev/null /MIDAS/log/temperatures.txt 17.10 For all FEEs (*except nnaida19 & nnaida26) which are currently disconnected) reprogram FEE flash memory using FEE_GF_Feb16_17.bin Power cycle attempt #1 - wait 4' STATE for nnaida9 returned with an error connect failed NONE connect failed attempt #2 - wait 6' STATE for nnaida4 returned with an error connect failed NONE connect failed attempt #3 - wait 8' - OK Installed updated Check software - Check.tml .tcl .js and Common.js Started DAQ - histogramming enabled - data transfer disabled Large fraction of FEEs not producing SYNCs, SYNC rate low (~20-30Hz) for other FEEs - see attachments 4 & 5 Note slow comparator 0xc8 (i.e. high) and fast discriminators (LEC/MEC) disabled Firmware version - attachment 6 System wide checks ASIC clock sync (30/30 fail) and ADC calibration (7/30 fail) work as before but new checks produce errors - see attachments 7-11 Additional screenshots from Master Timestamp Control - see attachments 12-17 00:40 PJCS identifies workaround to above problems - correlation controls now enabled for master timestamp FEE (nnaida5) only. May also explain issues with nnaida19 & nnaida26. PJCS will produce detailed, separate Elog entries Currently, all (30) FEE64s running OK with sensible AIDA SYNC rates. But. No spare fuses (16A/250V slow blow) for USB-controlled ac mains relay. Until Chris arrives in c. 9h. We will explore options to use *second* USB-controlled ac mains relay.
