16:04 DAQ continues running OK All system-wide checks OK except nnaida7 ADC calibration fails FEE64 temperatures OK - attach 1 Merger and Tape Server OK - see attach 2 & 3 16:30 DTAS and BigRIPS stop AIDA on file R2_406 16:35 Beam stop. AIDA plastic gain increased by a factor 2 Moved the lead bricks between AIDA and F11, 1 cm further away to the sides Chiller water level OK Humidity 34.6% Temperature 23.4 C Dew point 7.1 C 16:40 Beam restart AIDA run R2_408 DTAS 70 (from DTAS ELOG) BigRIPS 2030 (from DTAS ELOG) No obvious changes to the implantation pattern. May need more stats. Detector leakage current OK - see attach 4 17.31 nnaida14 3.*.H & 4.*.H spectra - attachments 5 & 6 Corresponds to RHS DSSSD#3 - decrease in rate observed but no evidence of systematic variation of HEC energy Modified implantdecay4.f to select events with x & y energy > ADC ch 1600 (c. 1MeV) to observe x-y hit pattern of light particles - see attachments 7 & 8 Low stats but light particle distribution appears to be symmetric with no obvious RHS cut 17:37 DTAS & BigRIPS DAQ stop Beam stop Lead moved back as before AIDA plastic gain decreased by a factor 5 17:40 DTAS and BigRIPS stop AIDA on file R2_416 17.48 zero *all* SortSas spectra 17:50 Beam restarting AIDA R2_418 DTAS 73 (72 is a mistake - ignore) BigRIPS 2031 18:43 DAQ continues OK All system wide checks OK - except nnaida7 fails ADC calibration as usual FEE64 temperature OK - see attach 9 Stats OK - see attach 10 Merger & Tape Server OK - see attach 11 & 12 Leakage currents OK - see attach 13 HEC & LEC events plots attached - attach 14 & 15 - note LEC in DSSD#3 are > 3 MeV only (light particle-like) 18:50 AIDA R2_427 DTAS 74 BigRIPS 2031 19.08 DTAS & BigRIPS DAQ stop - beam lost AIDA file R2_429 21:15 Beam is back - briefly AIDA R2_446 21:17 Beam lost - operators advise "this will take a long time" 22:16 Beam is back! AIDA R2_454 DTAS 78 BigRIPS 2034 Statistics OK - attach 15 FEE64 temperatures OK - attach 16 Merger & Tape Server OK - see attach 17 & 18 System-wide checks as usual DTAS reports rate in F11 down by 20%, and rate in AIDA plastic sees similar drop.
