00.30 AIDA file R2_26 DTAS run 007 BigRIPS run 2006 00:55 Merger status - attachment 1 TapeSever status - attachment 2 01:40 Before zeroing stats - attachment 3 Histos up to now saved in /homes/npg/spectra/specs-2019Jun16-01.46.50 Before zeroing histos - XY attachment 4 02:22 Up to AIDA R2_41 Stats - attachment 5 XY implants - attachment 6 02:29 AIDA R2_42 DTAS run 011 BigRIPS still 2006 04:08 Up to AIDA R2_55 Temps - attachment 7 Biases - attachment 8 Stats - attachment 9 XY implants - attachment 10 04:50 Did some major UI updates to merger /data02/2019data/dtas/scripts/parallelscript/runall_xe19_dev.sh If no parameters are passed, it asks to select each option one-by-one, showing available options For DTAS, if there is only one run for a given header, it automatically selects it After that, it checks that all the raw files actually exist Finally, it composes the command, asks the user if it looks OK, and then launches the script (or quits) (For experts, it can still take the original case where all 7 parameters are passed at the command line) There may still be some minor bugs, so for now we don't replace the original one until Alvaro can check 06:09 Stats - attachment 11 XY implant profiles -- attachment 12 06:30 DTAS 018; AIDA R2_80; BigRIPS 2009 Things getting a bit noisier? Merger - attachment 13 TapeServer - attachment 14 Stats - attachment 15 The FEEs corresponding to DSSSD1 are all showing factors 2 to 10 higher than just 30 min. ago F11 rates still near 180 cps, primary beam still around 130 pnA. 06:43 Before I can diagnose the high noise problem in DSSSD1, it goes back to normal Merger - attachment 16 TapeServer - attachment 17 Stats - attachment 18 Maybe the issue was from looking at the details too often :) 07:46 Shift change. DAQ continues running OK. Statistics show noisy DSSD #1 (100-200kHz) - see attach 19 Tapeserver also shows higher than normal write to disk rate - see attach 20 After a few seconds write to disk rate goes back to normal - see attach 21 Data items rate looks OK (500k). This was checked after the rates in DSSD#1 went back to normal - see attach 22 FEE64 temperatures OK - see attach 23 Implants look OK - see attach 24 System-wide checks OK except nnaida7 fails ADC calibration as usual. Reset Statistics Stats now OK - see attach 25 Reset HEC implants Timewarp events appear to be very frequent, consistently every 3-5 seconds. This seems to have been happening ever since beam was put on target. Analysed R2_94 using analyser in Desktop 3. No timewarps reported. See attach 26. 08:32 AIDA: R2_100, DTAS: 21 , BigRips: 2010 08:41 Another noise spike from DSSD#1 Observed up to 1,600k data items per second - see attach 27 Write to disk ~10 MB/s as before. See LEC xy plot - attach 28 HEC xy plot shows no hints of issues - see attach 29 Rate seems manageable - see attach 30 for analysis of noisy run R2_103. Note few seconds deadtime in some FEE64 and unequal number of Pause/Resume in nnaida 22 09:45 Rate in DSSD#1 back to normal. Data rate 500k, Write to disk 5 Mb/s. 10:00 Started compressing R2_* files to save disk space. Used nice gzip to compress to avoid conflicts with the DAQ. Status of compression can be checked in ELOG desktop in the terminal window running ls -alth 10:32 DTAS and BigRIPS stop runs AIDA on file R2_128 DTAS:24 BigRIPS 2011 10:56 Lost beam. BigRIPS and DTAS DAQs continue running. Accelerator operators advise beam should be back in 10 minutes. 11:12 Beam is back. BigRIPS & DTAS continue running and did not stop. AIDA file R2_133. 11:25 System-wide checks OK except nnaida7 fails ADC calibration as usual. Stats OK, but nnaida19 is a bit more noisy than befor (80k) - see attach 31 Temperatures OK - see attach 32 TapeServer & Merger OK - see attach 33, 34 - rates have been low since 10 am HEC xy plot OK - see attach 35 Reset online spectra Leakage current OK - attach 36 Encoding: HTML ELCode plain Suppress Email notification
