Test of Overhauled 2500 l/s Ion Pump at X-Mid

(Kyle R, Gerardo M)

Uncrated the recently received large ion pump at X-Mid, discovered that each of the high voltage feedthroughs at the pump had one of the two holes plugged with a half broken screw still stuck on one its threads, fortunately it was the bottom hole for both of the feedthroughs, which makes for an easy extraction.  After both holes were successfully cleared using pliers, hammers and drill bits, the pump was tested.  The large ion pump passed its tests, both sides tested good.  The ion pump is ready to be installed next year.  Tested SN70105.

Note: to be able to repair the high voltage fastening holes on the ion pump body, we had to remove the pump from the wooden pallet/crate, we used the crane to lift it and place it on a block, the crane activity started at 22:52 UTC.
