Qweak target had liquid up to HX (about 2/3 full?) by 1 am (25K, 36psi) when there was problem with 4K line. They stopped 4K and kept cold and slowly continue cooling down with 15K coolant (16g/s at the time and went up to 24 g/s this morning). It is about 34 psi now. Cryo probably fixed the 4K problem and they are going get back on cool-down with both 4K and 15K. If things go well, tthey could complete cool-down in a couple of hours. We will wait for another a couple of hours for them to get things stabilize. Then we can do our cool-down (starting at the beginning of swing shift?). Since we are able to stay on cold return, it should take less time than a full cool-down, but will depend on how much coolant we can have while Qweak target is cold. Out H2 loop temperature and the coolant return are at ~ 28K. D2 is at 73K. Vacuum at 8*10-6.
