[dsg-svt] RICH Assembly in EEL 124, SVT space needed in cleanroom

[Tyler Lemon]

Dear Stepan, 

The difference between Walt's video layout and the new layout is the RICH is rotated 90 degrees. Marco Mirazita and RICH INFN collaborators would like to have the RICH assembly structure rotated 90 degrees from Walt's original video design to have better access to RICH during assembly. This shouldn't affect the overall layout of EEL 124, but when Dario sent the step file of the new layout Walt mentioned it should be checked that there would be space for the SVT. 

Is there a step file that contains the layout of EEL 124 with the SVT? Could the SVT layout step file and the RICH layout step file be merged to ensure there will be adequate space for both? 

Best regards, 
Tyler

Tyler, 

Some time ago Walt Akers did a layout of the clean room that would accommodate 
both SVT and RICH. Why we are now discussing this question again? 

Also, we always had plans using the clean room over summer 2017 for final integration 
of the SVT and and MM trackers. So this should not be pressurize to anyone that SVT will 
be in the clean room toll fall of 2017.

Hello, 

Stepan has informed us that the SVT will be in the big clean room until late October 2017 (his email below in green). In November 2016, assembly of RICH is scheduled to start in the big clean room. While planning the layout, it was mentioned that the planned layout might not accommodate the SVT in the clean room. 

INFN collaborators have created a step file for the big clean room for RICH assembly. Could the SVT group confirm whether the RICH assembly layout will leave enough space for the SVT remaining in the clean room until late October 2017? Thank you in advance.

Hi everyone, 

Just to make clear, the Hall-B Silicon tracker will be in clean room 
until fall of 2017. 
Over summer it will be worked at to install micro-mega gas detectors.
