brian,
this is a good suggestion

For the connecting services in the Hall it would be good if DSG could have someone from Hall B to help as well to sort of using this as a training session to help get them involved to expand on the list of people that can work on the SVT.

Dear Marco,

Here is the estimate and the updated schedule. Bob mounted the BMT on the integration cart today, it is ready for the integration with the SVT.

For the external people critical for these tasks we would need support from:

- the survey group. I put tentatively the surveys in the clean room on 5/18, before and after the CVT integration. The exact date will be defined by Chris. The CVT alignment and survey in the hall will also depend on this as it is the prerequisite for the transportation of the CVT to the hall. The surveys in the clean room and in the hall would take a day each based on the prior experience.

- DSG. We expect the main tasks related to cabling the CVT on the space frame to be covered by them. Few days of work depending on the allocated resources for this task.

- Mohammad. Per preliminary agreement he will help with the CVT commissioning in the hall in June while I will be on vacation.

- FE. Ben (to install the SVT cosmic trigger, few hours). Mark (to help with cable routing to the new cable tray that Bob is planning to install for a clean safer path).

- CEA team. If CEA travel restrictions will be eased, CEA experts would provide support installing the BMT services and commissioning the DAQ. They would need an advance notice to plan the trip. Otherwise the remote support will be needed. Few days of work depending on the allocated resources for this task.

Dear Yuri,
another important milestone!
Many thanks to you, Rafo, the Saclay team the JLab tech staff and the DSG that supported (and are supporting!!) this job.
Please, let me have the list of (external) people critical for the next steps with the timeline of their presence on-campus: we are working on an extension of the access list and the is the right time to update it.
Cheers

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
