Minutes

Attendees: Elton, Beni (JLab); Shaun, Giovanni Alcocer (new graduate student), Zisis, Andrei (UofR); Matt (IU); Athens tried to connect; Will without audio (USM);

1. Announcements
   • New graduate student at Regina, Giovanni Alcocer, will be working on reconstruction effort and then analysis. Learning C++ and ROOT
2. October Collaboration Meeting
   • May not need the third slot, offer it to Curtis.
3. Action Items
4. Monitoring
   • Plexiglass sheets are in.
   • Documentation is being collected (primarily from Athens) for the sanding and painting. John hopes to start mounting next week.
   • NIM paper (Zisis) has been submitted. Preliminary communications with editors are taking place.
5. FCAL
   • Cabling complete!
   • The cabling is very nice and neat. Will ease access during maintenance. Provide an example to the rest of the detectors.
6. BCAL
   1. Reassembly of modules used in ESB during tests
      • The modules (#1's), which were used for testing modules in the ESB were opened and refurbished for use the the actual detector.
      • Traces of liquid were found inside the module on the silicon pad used for extracting heat off the electronics board.
      • Initial thoughts were that this was condensation, but closer inspection showed the liquid was somewhat oily. It could be anti-freeze from the cooling system.
      • Traces of the liquid were taken from the silicon pad and EH&S has sent them out for evaluation. The amount of liquid might not be sufficient for evaluation. No report yet.
      • We want to make sure the system is kept under nitrogen flow.
   2. Moved BCAL into solenoid!
      • Photos Downstream View, Upstream View, Closeup Upstream View
      • Removed readout assemblies from both sides of six modules (33-37 and 41) for inspection
      • All electronics dry. No visible damage
      • Assemblies on the rail pads very tight. Need to remove inside plate on some in order to take them off. This should be standard procedure.
      • Downstream no visible anomalies.
      • Upstream, boundary between module 41 and 40 showed a thicker dark band at interface (about 1-2 fibers instead of 0.5-1), but did not appear to be due to insertion of the module. Seems consistent with Regina archival photo End 2 Image.
      • Conclude: no damage found due to insertion of the BCAL into the solenoid.
   3. Cosmics Analysis | Shaun K.
      • Fits using two Gaussians. "Mean" parameter indicates the place where the two Gaussians are joined (it is not the mean of the distribution).
      • Elton: Expectations are based on beam test data, so they probably effectively include the acceptance for the light guides of the inner layer
      • Many of the runs with insufficient events has been traced to the use of root files that did not contain the full data set. These will be rerun.
7. Reconstruction and Simulation: BCAL Reconstruction Meeting 2013-09-17
   • Giovanni has joined the effort. George has been stalled due to the closure of universities. Will has investigated the reason for slow daily reconstruction of clusters and implemented a fix. He will give a talk at the collaboration meeting.
8. TDR update
9. Calibration of Calorimeters
10. Any other business
