Functionality Test Performed on EX/MX Turbo Pumps

Jordan, Janos

We ran the functionality test on the main turbopumps in MX and EX during Tuesday Maintenance (12/12/23). The scroll pump is started to take pressure down to low 10^-02 Torr, at which time the turbo pump is started, the system reaches low 10^-08 Torr after a few minutes, then the turbo pump system is left ON for about 1 hour, after the hour the system goes through a shut down sequence.
