Quick VPT Test Rig meeting -
minutes
Date of meeting: 16 June 2000
Venue: RAL
Present: P Flower, B Kennedy, A Turner J Williams
1. Mechanics
- JHW reported that 3 rows of 8 cans have been glued up.
Designing a limit switch to restrict the rotation should be simple.
2. Electronics
- Discussion of Brunel-style 3-way socket & connector. For
the RAL test rig such a connector must be small, cheap, and HT rated to at least 1kV.
3. Helium rig
- PSF has seen a rise in VPT gain with temperature of about 1%/degC
after He ingress. The mechanism for this is not understood, and it is possible that
the same effect may occur in vacuum VPTs.
