Discussion Points
- MC Cosmic Simulations: Blake's 4 GeV cosmic muon simulations incident on the front face and top of the module.
- Beam Test Gain Matching Plots: Blake's gain matching plots.
- E-log entries on HV-driven gain matching: see E-log entry 76 for the most updated HV settings; earlier there were problems with the north 15 (see Elog entries 6, 8, 9, 57); see 25, 26, 27, 28, 31, 52, 54, 55, 57, 74 for the progress in HV adjustment and channel readout. After Elog 76 the only time that I remember that the HV was changed was after Run 2407 for South 7 (from 2096->1900 V) to account for the saturation of the PMT at forward angles and near the end of the module, and this was restored after Run 2423.
- Cosmic paddle counter information: The paddle counters were placed as follows: the top one was about 1 inch above the top side of the BCAL and the bottom one maybe 2 inches below (from memory). They were horizontal (ie parallel to the floor). The counters were 10cm wide and ~40 cm long, and ~1/4" thick. Unfortunately we did not take and pictures of the setup. The 10cm long side was the one perpendicular to the BCAL long axis.
