Found SIP power unit for D2000 #4 not functioning correctly. Max current regardless of ion element connected to.

ML kindly loaned a spare. All D2000 work Ok now. Will have to send faulty unit for repairs back to SAES.

Opened up front part of tent just enough to allow GSI vacuum division to connect IE 514 and GSI ion pump. Tent to remain until January.

Left to do this year:

- Turn on GSI ion pump

- Turn on GSI IE514

- Close top gate valve

- Turn off maglev turbo (very close to magnet)
