* DC report
15 3 Blackmore, Victoria
** SSU/FC ramp went well
16 10 Boyd, Steven
*** Yay. But need to be careful that run settings have been tested before hand.
17 3 Blackmore, Victoria
** SSD diode test report
18 10 Boyd, Steven

** DS compressor progress
21 10 Boyd, Steven
*** Leak has not been found, but contamination continues rising. 
22
*** Will need to strip down the compressor (weeks work), then cooling the DS down will take more time. 
23 1 Boyd, Steven
** Aircon in RR2 now keeping rack temperatures beneath 30C.
24 10 Boyd, Steven
*** Racks are now cool enough. Area outside the control room is now a sauna.
25
** Water to conventional magnets.
26
*** A leak was sprung in the trench when we tried to put conventional magnet water supply on. This was a reflection of partial control of
27
the pumps in the trench which are on full power and putting too much pressure in the system. We have a route out of the problem. Water to
28
conventional magnets are off until Thursday at best. John wants to get into DSA to shut a valve to do the work and then needs to open it again.
