We mounted the following in the chamber:

• Iris frames - no S2 detectors or mylar
• Si pin diode mount with 0.9um mylar - no diode
• Target ladder with blank frames - same configuration as elog entry #41

At 15:20 we started roughing pumps Ecodry 1 and 2. We opened the manual gate valve followed by the T1600 valve.

After reaching ~10^-2 mBar we started the following turbos:

• Up 1
• Up 2
• Down 1
• Down 2
• T1600
• Entrance 3
• CSSM

By 15:30 the CSSM turbo had reached 56 krpm operating speed and the Up and Down turbos had reached 833 Hz operating speed.

At 19:51 just before we left the lab the pressures read, in mBar:

• TPU1 = 3.7e-6
• TPU2 = 6.9e-7
• TPD1 = 1.0e-6
• TPD2 = 1.2e-6
• CHUP = 6.0e-6
• CHDW = 1.4e-5
