Late entry, tests were done last Tuesday, May 16th 2023.

A functionality test was done on the corner station turbo pumps  The scroll pump was started to take pressure down to low 10^-02 Torr, at which time the turbo pump was started, the system reached low 10^-08 Torr after a few minutes, the turbo pump system was left ON for about 1 hour.  After the hour the system went through a shut down sequence, turbo is not spinning and power is turned off.  No issues were encountered while performing the functionality test on the 3 turbo pump stations.
