  • Some description and tutorials how to take the calibration scans is https://atlaswww.hep.anl.gov/asc/wikidoc/doku.php?id=itk:testbeam. All figures corresponds correspond to the previous scan on Sep 29 ( RTISC2B/config/RTISC2B__cern__93.cfg)
  • 5.00AM: New ANALOG and THRESHOLD scans. It was found that, without calibration, we see large number of low-efficient analog channels. About 70% of channels have 40 counts (50 expected). This drastic difference compared to Sep 29, right after installation, when about 1% of channels showed 40 counts (mostly for first 2 rows). The noise level from the threshold scan increased by a factor 2.
  • 5.15.00: New calibration file for the RTI module is RTISC2B/config/RTISC2B__cern__158.cfg.  It was noticed that the noise level increased to After the calibration,  it was noticed a large number of bad modules, large noise 400e, and the  analog scan has more loses on the left edge.
