Agenda
- Review upstream gas plenum configuration
- Discuss grounding scheme
- Discuss conductive rubber tube dimensions
- look at grounding strip on connector board
- Discuss layers connection
New Action Items
- Fernando to look at stripping tools to reduce the need for large pcb on connector
- Gary to verify cable for connector to crimp pin
- The HV Cable is RG316. It has a 0.1 inch OD.
- Slava will layout Fernando's stud grounding option
- Gary to supply sketch of CMU grounding option
- Gary to check if he can still get conductive rubber boot used previously
- Slava to update layout of cable to crimp pin per discussion
- Tim to see if cable restraint bushing can be made
- What needs to be done on al plate to ensure electrical connection? all
- Gary to get sample of polycarbonate to test
Action Items/Decisions from Previous Meeting
- Endplates and aluminum feedthrus awarded -
- less expensive than originally anticipated due to opening up of tolerances
- Checked IDEAL tool and manufacturing in Chicago.
- no longer in business
- Tim to discuss with vendor repair of end plates if hole messed up
- less expensive than originally anticipated due to opening up of tolerances
- Carnegie Mellon to use GARFIELD to check electric field around crimp pin insert
- Increased length of pin insert to match distance from wire to straw
- CMU to look over to see if piece tolerances can be loosened to ± .001 in
- less expensive than originally anticipated due to opening up of tolerances
- OK if we open end plate to .005 tolerance on hole positions, need to reduce straw diameter to prevent interferences
- Complete, new straw inside diameter 0.611 inches
- Conductive rubber tubes cover 30% of gas holes - ok, added additional hole
