Minutes and Action Items
- Rory discussed the importance of making sure the downstream detector has it's x-ray port facing downstream for access. With this in mind the 2 vertical downstream detectors will need to have a gap in between to accommodate the HV cables protruding past the planes. The x-ray port will be 15inches from the center of the detector
- Elton will label the detectors as the testing goes along to ensure we know what detector is installed where
- Discussed OSP -
- Beni put the OSP on the table for reading and signatures. He will need a table to put the chambers on
- Need scintillator paddles in the EEL 126
- Need to hook up gas to the detector being tested first
- There will be a 10" vacuum tube installed DS of the detector
- 2 scintillator paddles will be installed vertically on the DS end of the detector close to the beam maybe 10" from the center
- We discussed the clearance for the SHV connectors and using a right angle connector. Stephanie reminded us that we had made clearance in the base to allow room for the straight connector.
Action Items
- Tim to look at chambers in EEL to determine how big a gap is needed between the DS detectors
- Mark to arrange bring scintillator paddles to EEL
- Mark to arrange getting tables in the EEL
- Beni to get with Scot to hook up gas when ready
- Stephanie to model paddles and x-ray ports in the 3D model and drawings
