Note any problems or unusual conditions in the comment block.

 

 

 

2119

Go to klyston gallery. In all likelihood, folks will check as many CM downstairs as possible before going upstairs, but it doesn't make for a pretty, per-CM procedure...
Verify the WR650 is still pressurized and connected to the SSAs for cryomodule under test

 

 

 

2220

Inspect cable connections to RF racks for disconnected cables. DO NOT OPEN DOORS OF RACKS. If there is a concern, note in comments and call LLRF Group.
