On Wed May the 17th I check the status of the vacuum in the south arm and in the south end vacuum chamber.
There are a total of six pressure measurements along the south arm.
- Near NM2
P1 = None (NM2 is not evacuated)
P2 = 2.5e-8 Torr
- Mid-arm
P1 = 2.0e-8 Torr
P2 = 2.5e-8 Torr
- Near EM2
P1 = 1.2e-7 Torr
P2 = 1.0e-7 Torr
