09.30 Detector biases and leakage currents - ambient temp +24.9 deg C - attachments 1-2 10.08 Connection lost to nnaida27 and nnaida28 Most recent save of settings DB key 2016May31-23.32.46 12.00 Replaced nnaida17 & nnaida18 with FEE module previously used for nnaida31 & nnaida32 Pulser walkthrough BNC PB-4 settings 90,000 - 10,000 @ 10,000 step x5 attenuator (was x10 previously) t_r = 50ns tau_d = 50us polarity - rate ~ 150Hz INT, delay MIN polarity + by EG&G Ortec 433A N.B. - polarity terminated at end of AIDA adaptor chain, + polarity not terminated Spectra saved 12.32 ( to directories tagged around June 1, 2016 05.29 ) BNC PB4 pulser rate set to ~5Hz 207Bi source at front of snout and 2x 60Co sources above DSSD3 14.00 Rebooted aidas1 to cleanup merge Changed config to 24x FEE64s Clock issues with nnaida23 - clock not locked status 0x6 - see attachments 3-9 18.00 Replace current nnaida19 (no histogramming, reSYNCs OK but timestamp not sync'd wrt timestamps of other FEE64s). Replace current nnaida23 Following powerup obtained clock not locked - status 0x6 for nnaida5 (master) Replacement nnaida19 also does not histogram, reSYNCs OK but timestamp not sync'd wrt timestamps of other FEE64s) With help from PJCS investigate above issues and change timestamp master from nnaida5 to nnaida6 ( /MIDAS/config/HttpdTcl/aidas1/startup.tcl and /MIDAS/config/HttpdTcl/nnaida5/startup.tcl ) to change definition of timestamp master. Able to operate DAQ and obtain AIDA SYNCs and WAVE SYNCs with TS_SYNC 0x0 _only_ PJCS will also investigate using system in T9 at STFC DL Restored settings 2016June1-17.27.?
