Quick VPT Test Rig meeting - minutes

Date of meeting: 23 January 2004

Present: KWB, PSF, BWK, ALL, CL, MS

1. Status of rig: 6 preamp boards damaged inadvertently - tantalum capacitors on 5V rail blown.  Bristol have spare boards - should be installed early next week.  Vince Smith has offered to attempt to repair the damaged boards.  The damage occurred because a length of copper tape fell into the low-voltage power supply.  Steps will be taken to prevent any recurrence.
2. Visual inspection rig: Moved to lab 7 darkroom. ALL has inspected 300 of the latest batch (6901-7300).
3. VPT grading station:  Set up in R12.  JHW is in process of upgrading the PC to run XP.
4. VPT storage in R12:  1 fridge is currently under nitrogen, with another awaiting gas connection.  A third is needed to store the current stock of VPTs.
5. Brunel report:  About to order mechanical and optical parts to complete the multi-VPT torpedo. system.
6. Safety: Discussion of CE labelling of VPT test rig.  This requires a thorough risk assessment and documentation of safety aspects of rig design.  Interlock and warning lights will be installed as soon as possible after the installation of new preamp boards.
