[Dsg-ltcc] LTCC Leak Sealing Meeting

[Marc McMullen]

*Attendance*: B. Miller, D. Insley, D. Anderson, M. Ungaro, B. Eng, M. 
McMullen, G. Jacobs, T. Lemon, A. Hoebel, P. Campero

Discussion on current leak rates for the LTCC sectors which have gas 
flow, and how ambient pressure affects the sectors.

Hall B will start sealing sector 1 next week. After sealing on the 
floor, they will hook up gas and DSG will measure the leak rate on the 
floor, before the detector is reinstalled. After installation, DSG will 
monitor the leak rates.

This will repeat until all available sectors (except 4, which has been 
dismantled) are completed.

There was discussion on the purchase of C4F10, George provide costs and 
lead times. There has not been a final determination of gas procurement 
from management.

Discussions on a distillation/recovery system is on-going, within Hall 
B/Physics Management.
