NNAIDA 22, 21, 14, and 13 had a much higher count rate after the power cycle, and what seems like a lower threshold. We can't observe the pulser peak in any of those. NNAIDA 13 has the highest count rate, and the waveforms show what looks like noise with a regular frequency (attachments 4 - 7) For reference, we include the waveform of other positive FEEs 8-11 02:51 Bias and leakages ok - attachment 13 System wide checks ok Good Event statistics - attachment 14 Fee Temperatures - attachment 15 03:03 BigRIPS and BRIKEN stop daqs AIDA on file R5_208 03:04 BigRIPS starts run 3009 BRIKEN starts run 9 AIDA on file R5_208 04:03 BigRIPS and BRIKEN stop daqs AIDA on file R5_230 04:04 BigRIPS starts run 3010 BRIKEN starts run 10 AIDA on file R5_230 04:09 System wide checks all ok Bias and leakages ok - attachment 16 Fee Temperatures - attachment 17 Good Event Statistics - attachment 18 04:48 DSSD rates from R5_244 * DSSSD # 1 count: 1239207 old count: 1155424 dt: 1.04 s LEC rate: 80379.42 Hz * DSSSD # 2 count: 1684042 old count: 1567549 dt: 1.04 s LEC rate: 111760.61 Hz * DSSSD # 3 count: 806937 old count: 752064 dt: 1.04 s LEC rate: 52643.85 Hz * DSSSD # 4 count: 505814 old count: 472642 dt: 1.04 s LEC rate: 31824.43 Hz * DSSSD # 5 count: 208086 old count: 193231 dt: 1.04 s LEC rate: 14251.53 Hz * DSSSD # 6 count: 335686 old count: 313190 dt: 1.04 s LEC rate: 21582.13 Hz * DSSSD # 1 count: 8 old count: 7 dt: 1.04 s HEC rate: 0.96 Hz * DSSSD # 2 count: 193 old count: 181 dt: 1.04 s HEC rate: 11.51 Hz * DSSSD # 3 count: 872 old count: 810 dt: 1.04 s HEC rate: 59.48 Hz * DSSSD # 4 count: 637 old count: 601 dt: 1.04 s HEC rate: 34.54 Hz * DSSSD # 5 count: 89 old count: 81 dt: 1.04 s HEC rate: 7.68 Hz * DSSSD # 6 count: 71 old count: 65 dt: 1.04 s HEC rate: 5.76 Hz 05:01 BRIKEN and BigRIPS stop DAQs AIDA on file R5_250 05:02 BigRips starts run 3011 BRIKEN starts run 11 AIDA on file R5_250 06:02 BigRIPS and BRIKEN stop their daqs AIDA on file R5_272 06:03 BigRIPS starts run 3012 BRIKEN starts run 12 AIDA on file R5_272 06:06 System wide checks all ok Bias and leakage currents ok - attachment 19 Good event statistics - attachment 20 FEE temperatures ok - attachment 21 06:16 Analysis of R5_270 - attachment 22 Three MBS errors 06:34 130Cd decay curve - attachments 22 and 23 Despite the large amounts of noise in the detectors it is still possible to observe decay curves. They are cleaned up a lot by applying a multiplicity cut (attachment 22 with attachment 23 without. Further cuts and vetos could be applied to clean up further. The fit in attachment 22 gives a half life of 182ms which is not quite the expected 162ms but a reasonable first fit. 07.14 Layout - 1.8.W waveforms - see attachments 24-27 No significant change in intrinsic/extrinsic noise cf. previous screenshots nnaida13 ASIC 1-4 waveforms - see attachments 28-31 - range 10020us 07.24 BRIKEN and BigRIPS stop DAQs AIDA on file R5_300 07.25 Stop AIDA DAQ Cycle detector biases Start AIDA DAQ 07.38 BigRips starts run 3014 BRIKEN starts run 14 AIDA on file R6_1 07.45 nnaida13 ASIC 1-4 waveforms - see attachments 32-35 - range 10020us 08.07 all system wide checks OK Encoding: HTML ELCode plain Suppress Email notification
