I have to leave for a dentist appt. but expect to resume leak checking GV6 when I return (1530?) -> The Corner vacuum equipment is being pumped only via the YBM Turbo pump which is being backed by a leak detector and CP2. IP1, IP2, IP5 and IP6 are valved-out. This is a temporary pumping arrangement. Also, the instrument air used to control CP2 is not enabled currently which is also a temporary state.
