[Dsg-halla_gas] gas panel and exhaust sensor locations

[Marc Mcmullen]

Good Morning All,

I did not received any responses to my previous email on the locations of the gas panels. I would like this information so that I can prepare the agenda topics for the Hall A GEM gas distribution monthly meeting.
Jack could you verify the information on the locations?

Kondo and Evaristo, could you provide answers to the questions about the GEM layer assemblies?

Regards,
Marc

Good Morning,

DSG is moving forward with design plans for the GEM gas flow readout system. I have process majority of part procurement to set up the system. Chassis, panels, and component delivery will start within weeks.

I would like to confirm a few details of the system installation.

I have noted the proposed location for each GEM gas panel in red. Each is located just beyond an electronics hut.

  1.   Are these the correct locations?
  2.   Is there room inside of the huts for the gas panels (full size racks provided by Jack)

This is a photo of one of the SBS back layers in the EEL building.

  1.  Are these dimensions for the cable tray accurate?
  2.  What is the distance between the baseline of this cable tray and the baseline of the next cable tray when the detector is assembled?
  3.  Are these numbers the same for the front layers, if not what are the dimensions?

We will use this information to develop the exhaust sensor/multiplexer housing.

Regards,
Marc
