HAM1 Vacuum Work, Installation Of A New Gauge and Turbo Pump

(Jordan V., Travis S., Gerardo M.)
Today we installed a new gauge on the 16.5" conflat on top of HAM1, installed on the top central port, D1.  A single gauge replaces a gauge pair combo, pirani and cold cathode, this gauge will be used for the high voltage interlock system for HAM1.  The gauge still needs the installation a couple of cables for it to work.

The turbo pump was the second item that was replaced on HAM1, an outdated and noisy turbo pump was removed and replaced with a new turbo pump.  No issues were encountered during the removal or installation of the new pump.

All of the affected conflats will need to be checked for leaks.
