Subject: Vault beamline beam position monitor 

The Beam Position Monitor between 1VB1 and 1VM3 has been installed. The indium joints are leak tight, however the V flanges are leaking slightly. The leak is small enough to still be able to run beam.

The Pin drive at the BPM and 1VB1 joint was replaced with a new one. The pin drive that was originally there had a bent screw drive so it was retired. The clamping collars at both joints were reused.
