Chandra, Kyle, Dave:
After the MX gatevalves were closed this morning, the pressure in the X1 beam tube (Corner Station to MX) has been steadily rising as anticipated. The MX end exceeded its alarm point of 5.0e-09Torr several hours ago followed by the CS end an hour later.
Chandra has requested that the alarm level for these two gauge readings be increased to 1.0e-08Torr. I have made this change and restarted the alarm system

Chandra also requested that the alarm bypass on HAM6 be extended through to the end of next week
Bypass will expire:

For channel(s):
H0:VAC-LX_Y0_PT110_MOD1_PRESS_TORR
Looks like we've exceeded the 1e-8 Torr setpoint on PT343. Tomorrow we will raise setpoint to 2e-8 Torr.
PT343B alarm level raised to 2.0e-08Torr
