00:00 New day. The DAQ continues OK Beam setting 2 for enhanced yield of Sn100 No degrader Statistics OK - see attach 1 FEE64 temps OK - see attach 2 Merger & Tape server OK - see attach 3 & 4 Bias OK - see attach 5 All system-wide checks OK, except nnaida7 fails ADC calibration 00:19 AIDA R2_473 DTAS 82 BigRIPS 2036 01:50 FEE temps and bias/leakage currents OK Data rate continues at ~620k items/s and ~5.1MB/s ASIC check performed successfully 02:29 DTAS run 85 BigRIPS run 2037 AIDA ~1.5GB into R2_492 02:30 DTAS reset correlation scaler at start of R2_493 Confirmed by change in value in Correlation status & control @ aidas1 window. 02:36 DTAS run 86 started BigRIPS run 2038 AIDA file R2_494 04:38 DTAS run 88 stopped. AIDA run R2_512. DTAS run 89 started. BigRIPS run 2039 AIDA run R2_512 (1.8GB) Temps + bias/leakage currents still ok Data rate still ~600k items/s and ~5MB/s Individual Good data rates remain roughly constant (see attachment 6) All system-wide checks passed, except nnaida7 fails ADC calibration 05:48 Stats and histograms zeroed 06:28 DTAS run 91 stopped. AIDA run R2_528 at the time. DTAS run 92 started BigRIPS run 2040 AIDA run R2_528 07:50 Made some basic observations with the first file merged after the setting change Attachment 7 shows implant x:y plots for each DSSD Attachment 8 show PID for second setting with 100Sn highlighted in red and 96Ag in magenta 08:21 PID per DSSD Attachment 9 Sn100 per DSSD attachment 10 Sn100 Velocity against DSSD 11 Sn100 Velocity against DSSD Energy attachment 12 08:29 DTAS and BigRIPS stop AIDA on file R2_546 DTAS starts file 95 BigRIPS run 2041 AIDA on file R2_547 08:53 Stats ok - attachment 13 Temps ok - attachment 14 System wide checks ok ASIC check ok Bias and leakage still ok though DSSD3 continues to rise - attachment 15 Merger continues with data rate around 700k - attachment 16 09:43 With the new implantation profile depositing most of the Sn100 in DSSD2 but some in the 3rd the plan is to put in place a 200 micron degrader to bring the deposition into the centre of detector 2 10:15 Overnight MIDAS analysis has been completed.
