Hall C Status:

D. Meekins is almost done with target work and will be ready to cool down late in the morning today (09/15)
There are significant issues with Hall C dumpling vacuum which will have to be addressed before Hall C can close on Friday
Currently, target chamber vacuum is 3e-5 torr and downstream dump-line is 200 torr. Meekins does have some recommendations
for that system,  but will not make any changes without  talking to Walter Kellner first.

As of now, Meekins is inclined to cool the target only and wait until the issues are resolved with the vacuum to condense H2/D2.
