Moving pucks with the aim of putting a GaAs puck in the HV chamber for HV conditioning (now delayed or cancelled due to prep chamber long manipulator)

Pucks 10, 31 and 3 were moved from the suitcase to storage manipulator 1 (closest to HV chamber)

Pucks 34, 9 and 32 were moved from the prep chamber back into the suitcase. Two of these are bulk GaAs, one is a used broken SSL

The mirror puck was then removed from the HV chamber. Inserting it last week went ok, but then the bearings stopped working well.

Last week, Riad and I found that the long manipulator that moves photocathodes from the prep chamber where they are heated and activated to the high voltage chamber was not working well.

Today, Joe and I had the chance to investigate more. The magnetically coupled manipulator has bearings in the vacuum which seem to be catching, and no longer able to move reliably and smoothly.

Following the manual, we adjusted the teflon sliders, which are outside the vacuum, reseated the external magnetic coupling and tried actuating it again.
