ran into noise again, about to increase thr

moving telescopes back closer together as "gbl" tracking seems to have a problem with the new geometry (or we are underestimating material budget of our DUT)

disconnected piggy

Petra is most likely causing our efficiency drops in time, testing now if timeshift is rate dependent (see energy)
  398   Fri Jul 14 10:29:10 2023 tb-crewproper data taking RD50-MPW3unknown91unirradiated1.9K4.8Low Flux LowelectronGood   
reduced thr to 1.15 and deactivated rows, trying to go as low with thr as possible without noise for efficiency
  403   Fri Jul 14 10:48:46 2023 tb-crewproper data taking RD50-MPW3unknown91unirradiated1.9K4.2Low Flux LowelectronGood   
thr 1.08V is noise
  413   Fri Jul 14 13:56:09 2023 tb-crewthreshold optimization RD50-MPW3unknown911e141.9K4.2Low Flux LowelectronGood   
now really going for Sams irradiated chip
  415   Fri Jul 14 13:57:18 2023 tb-crewirradiated RD50-MPW3unknown911e141.9K4.2Low Flux LowelectronGood   
that was noise
  417   Fri Jul 14 14:05:27 2023 tb-crewirradiated RD50-MPW3unknown911e141.9K4.2Low Flux LowelectronGood   
that was overkill, thr 1.3V it is
  419   Fri Jul 14 14:51:11 2023 tb-crewirradiated RD50-MPW3unknown911e141.9K4.2Low Flux LowelectronGood   
change geometry btw due to montage off cooling setup
  420   Fri Jul 14 15:50:55 2023 tb-crewirradiated RD50-MPW3unknown911e141.9K4.2Low Flux LowelectronGood

thr 1.20V is noise
  427   Fri Jul 14 16:26:16 2023 tb-crewirradiated RD50-MPW3unknown911e141.9K4.2Low Flux LowelectronGood   
thr 1.225V, -8.6 deg C, was running in noise, deactivated lower 30 rows
  437   Sat Jul 15 10:03:28 2023 tb-crewirradiated RD50-MPW3unknown911e141.9K4.2Low Flux LowelectronGood

  438   Sat Jul 15 10:04:38 2023 tb-crewirradiated RD50-MPW3unknown911e141.9K4.2Low Flux LowelectronGood   
masking all rows below row 50
  440   Sat Jul 15 10:06:28 2023 tb-crewirradiated RD50-MPW3unknown911e141.9K4.2Low Flux LowelectronGood   
there is a noisy pixel
  442   Sat Jul 15 10:22:32 2023 tb-crewirradiated RD50-MPW3unknown1051e141.9K4.2Low Flux LowelectronGood   
changed bias, is short before breakdown now
  445   Sat Jul 15 10:40:09 2023 tb-crewirradiated RD50-MPW3unknown1051e141.9K4.2Low Flux LowelectronGood   
pixel 57:30 is noisy, masking it
  451   Sat Jul 15 11:18:48 2023 tb-crewirradiated RD50-MPW3unknown1051e141.9K4.2Low Flux LowelectronGood   
masked 2 more pixel
  453   Sat Jul 15 11:21:28 2023 tb-crewirradiated RD50-MPW3unknown1051e141.9K4.2Low Flux LowelectronGood   
problems with noisy pixels now, masked 56:30
