BCAL Reconstruction Status
Blake gave a brief status report on some of the recent work done on the BCAL reconstruction and simulation. Much of this was started during a recent trip Blake made to IU to work with Matt and Mihajlo. The main changes to the code were:
- Time smearing of the BCAL hits
- Low energy threshold recalculated and set
Results of a study comparing resolutions of a BCAL design with the nominal 6x4 and the alternate 3x3 inner region readout segmentation were presented. The 6x4 segmentation corresponds to a readout design using SiPMs and the 3x3 using Planacon PMTs. The studies indicated very little difference in the energy or angular resolutions of the 2 schemes. It was noted, however, that the same low energy threshold (4.8MeV) was used for both cases even though the Planacon design is expected to have a lower threshold. The resolution has a dependence on the low energy threshold.
