Pumping down: TS loaded with a LP-SIS container for spectrometer test. 

Started heating up the target container: up to 300A.

Last week: the LP container was heated up to TGHT 580A and TBHT 230A, and cooled down before the weekend. 

Pumping again (LP container in) for one more check. Last check was completed on July 26: up to 400A. 

Vented the chamber today (July 27). 

Did another test over the weekend. Currently the PSs are off and the chamber under vacuum.
