[dsg-svt] [Dsg-mvt] [Dsg-rich] space in back of EEL 125

[Amrit Yegneswaran]

we are looking at a new chapter on how to proceed, given the delay. 
not a re-iteration of the old schedule. 
in the end, if appropriate and reasonable changes aren't implemented one shouldn't be surprised at the outcome. 

RICH needs clean room space at the back where the SVT/MVT is to assemble the aerogel/the mirrors etc. 
the svt/mvt doesn't need clean room space for cosmic data, am i wrong? 
anyway, mine is only to suggest how to run things smoothly as i see it , not enforce it. 
klaro!

Indeed, we plan to move the CVT during the 1st week of November. 

CVT integration took place in May. There will be no MVT shimming. 


Next week there will be work in the clean room on replacing the tiles of the outer BMT layer. 

There is some work to be done by the DSG for the SVT: 

- patch panel rework (scheduled for this week) 

- CSS GUI for the hardware interlock (waiting for DSG to provide the date when it can be installed and tested) 

We are taking the CVT cosmic data for alignment. 


In October we will continue taking alignment data, work on the trigger rate issue, and verify stability and performance of the central tracker in the clean room. There are no plans to move the CVT to EEL125. 

Irakli will assemble the MM DAQ test stand in EEL125 when he comes next week. He made arrangements with Sergey and FE group.

Amrit, 

We have been informed by Bob Miller himself that this move-out date of Oct. 1st you mention is obsolete. As far as we are aware, the real date will be closer to end of October, maybe early November. I am surprised you are not aware of this. 

Maybe Bob can comment and give us all the same information. 

A MVT crew is coming to Jlab October 2nd FYI.

FYI: svt/mvt was scheduled to be move out of the big clean room and into the hall by 1st. oct. 2017. 
the mvt crew is yet to appear. 
so, it is best to organize the FT area, which as of now, is just full of junk, so that the integration of the svt/mvt can take place in the shower curtain room in the FT area. 
this way there will be no conflicts, no issues moving the svt/mvt out of eel to the hall.

Hello Walt, 

In regards to the layout of EEL 124, it was decided some time ago that RICH would be able to use the entire cleanroom once SVT and MVT have moved to Hall B. 

SVT/MVT installation is planned for October, but if it is delayed, could we move plan to move SVT/MVT into a staging area to free up space in EEL 124 for RICH assembly? 

This staging area for SVT/MVT could be EEL 125 in the area previously occupied by FT. This area is now only occupied by chairs, tables, and other stuff left behind by FT. 

If the former FT area in EEL 125 is cleared soon, it would also open a path for the SVT/MVT to be taken out of EEL 124 via the back roll-up door, giving more space in EEL 124 for RICH assembly as a pathway would not need to be clear to the front roll-up door. 

Please let us know whether the former FT area can be cleared out, as RICH will soon need more space for its assembly. 

Best regards, 
Tyler
