Safety tour went well with only a few minor outstanding issues. Completed sign-off is expected in the next few days.
When leak checking complete, the aim is too cool with He over the weekend and then start with H2 first thing Monday.
Need magnet and LH2 babysitters next weekend.

Status of alarm clearance (DC/Ajit) - Ajit working through list. Many are known accepted faults. Disabling some others.
Update on tracker readout (Melissa) - No warm up now. MU and PK coming on Thurs for pulser run. Will put plan regarding waveguide swaps together then.
Update on DS Shield pressure (Henry) - Jerg had a look at DS and thinks problem relates to absorber contamination. Proposes flush with N2. Action Thurs/Fri
Update on SS QPS connector issue (Craig) - Pulled out current measurement unit and clicked on SSU connector properly. Seems slightly dodgy though presently stable. Will monitor from here.
