Minutes
- Elton stated that the 7th chamber was in testing. 1 of the first 6 had noise. Rory may come after Thanksgiving to repair
- Discussed moving 2 chambers to the TEDF some time in the coming weeks to test installation onto the steel absorbers. We have straps at JLAB and will load on to pickup truck and drive very slowly
- Elton will check with Chris Stanislav for sub-D connectors
- Stand is fully assembled in TEDF, we will install an absorber in the coming weeks to check the installation procedure
- There was a discussion of rotating the downstream most chamber to horizontal for better performance. We will need to check that it can fit
- Discussion of removing or cutting vertical cable manager to accommodate DS most chambers
- Elton also requested that the chambers be oriented in such a way that the cabling/connectors will be consistent
- Stephanie needed the dimensions for the scintillators for the 3D model
Action Items
- Elton to get with Chris on sub-D connectors
- Elton to come up with desired orientation of each chamber
- Tim to measure cable trays again in Hall to determine if the chamber can go horizontal
