Awaiting Authorization/Investigation - after cavity 5 High Vacuum Fault
After preparing the CMTF for PSS MODE --> RUN
We attempted to bring cavity 5 up with minimal power (GDCL 'clamp ~0.05 and GLOS ~1.0) in PULSE MODE. Cavity tripped on vacuum. We allowed vacuum to recover, dropped the clamp from 0.05 to 0.005, tried to get cav 5 on in PULSE MODE, and tripped on vacuum exceeding 5e-7 Torr
We then followed Operating Envelope Violation protocol, Crashed RF and CPS, removed keys, dropped PSS to OPEN, Made escalations per TOD section 3.5.2, etc...
