Dear All,

BMT integration and cabling is complete. All tiles are operational, 
tested with premix gas under the nominal HV settings. Pedestals are 
posted to the HBMVT elog. BMT is being flushed with argon. Bob will 
mount the BMT on the integration cart on Friday.

SVT cabling is complete. All modules are operational, calibration 
results are posted to the HBSVT elog. SVT sensors will be kept cold 
until the survey.

Per agreement with Chris next week the survey group will do SVT survey 
and BMT alignment (after it is integrated with the SVT on the cart).

After the integration the CVT will be transported to the hall, craned to 
the space frame, and mounted on the CVT cart. At this stage we would 
need support from the Detector Support Group to rout and connect the 
cables to the crates. We also rely on help from Mohammad in June to 
commission the tracker and from the Fast Electronics group on 
reinstalling the cosmic trigger to collect alignment data during the 
summer time. If travel restrictions will be eased, CEA team will join us 
on the work in the hall.

Yuri and Rafayel
