We are flushing about 400 l/h Ar-CO2 (40-60) through the racks of the CSC + End-cap (5 distribution units). The chambers are bypassed. Two volume buffers are connected to the rack in ME+1, to be able regulate pressures better.

Current Issues

22.7.07

Cooling un-operational in SX5 from 16:35; temp high, and we still do not have a T sensor DSS cut off; DCS works nevertheless; though still to understand why some rack temps are not displayed. short report

20-21.7.07

Both Lifts un-operational last evening, but ok now. TCR - 72201 was called yesterday; lifts were fixed; but panels were left there. That created a confusion this morning. The shift assumed that the lifts were not working due to the signs on the panels, and three hours were lost.

Cooling problems as well - no sms messages received - to be checked on Monday 23.7

Look for the temp excursion sample from S1D09

Highlights of the week

EB SM Installation - 11 modules inserted

YB0 Services Installation -

Magnet Cryo test begin
