Tentative Agenda
- Announcements
- October Collaboration Meeting
- Action Items
- Monitoring
- FCAL
- BCAL
- 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.
- 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.
- Reassembly of modules used in ESB during tests
- Reconstruction and Simulation
- TDR update
- Calibration of Calorimeters
- Any other business
