Functionality Test Performed on EY/MY Turbo Pumps

We ran the functionality test on the main turbopumps in MY and EY during Tuesday Maintenance (8/29/23). 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.
No issues were encountered while performing the functionality test on these 2 stations.
