Subject: Pumpdown tomorrow  

Linked is the pumpdown procedure, contained in the old 40m documentation. The relevant procedure is "All Off --> Vacuum Normal" on page 11.

I just spoke to Jon who asked me to make this elog - we will be ready to test one or more parts of the pumpdown procedure tomorrow (12/20), so we should proceed as planned to put the heavy doors back on EY and OMC chambers at 9am tomorrow morning. Jon will circulate a more detailed procedure about the pumpdown steps later today evening.
