Minutes

-James fabricating new cell with straight torlon base and aluminized Kapton(plus a spare) - it will take approximately 4 weeks - Elecronics are done, a feedthru is needed for thermometry - Target group fabricating an interlock box to hard wire turn off the compressor - Target group would like a kill button located in the counting house to turn off the compressor (Dave B to check)- should be ok - (2) 55 gallon Tanks have been ordered (Dave M) - Target group will procure the relief valves, they will be plumbed through the vent stack - Matt to work on vent stack design from manifold supplied by the target group - Compressor power is 208 3 phase - 5 wire, outlet exists on solenoid piers upstream - Chris has spoken with Patrizia and tentatively scheduled safety review for the 2nd week in May. Steve Christo and JP Chen are reviewers - Alexandre will check if we can use 5mil kapton window between target and upstream beamline (2M from target) - Hall D will supply a 4" gate valve and turbo for pumping on vacuum chamber - Target group will supply a diaphragm switch hard wired to turn turbo off - Josh requested no feedthrus or wired connections on the sides of the vacuum chamber for easy access and ability to remove upstream plate in situ - Rich/Matt working on location of turbo pump - Vacuum chamber bottom flange to include 4" pump port and 4 - 2 3/4" conflat ports - Chris to email Javier outlining responsibilities - Hall D will deliver assembled cart to target group. This is a priority to enable the Target group to start poulating the cart to make end of June date for test and delivery - Rich to supply James with the latest start counter model to ensure proper geometry - Tim will get with Jim Dahlberg on fiducial points.
