Action Items for the Installation and Integration group

1. Cryostat design

TCO interface

  • List of the components using the TCO
    • -> Where is the info?
    • -> Who?


  • Space inside needed to close the TCO
  • TCO dimensions: W between 1.1 and 1.2m H will depends on roof penetration (something like membrane to membrane - 0.7m)
  • Bob Flight is a potential candidate after the reviews (~December)

Roof penetration locations

  • Detector support structure interference
  • -> Jack
  • Instrumentation feedthrus
  • HV feed thru
  • Detector readout feed thru

Cable routing to the feedthroughs

There are two options for reading out the lower APA:

  • Either the cables are routed up through the upper APA
  • Along the floor and up the wall.

The floor option changes the number and location of the feedthrus. There are also grounding implications.

  • Prototyping could be useful (trial at Ash River? The APA frame will get there between 7th-14th)
  • The info is from Lee
  • -> Jim will set up a meeting with Roxanne/Marvin/Ron and Matt/Lee and Dave from photon to start the discussion
  • ->Need this around Xmass for final decision in mid-January

Floor loading

The floor loading will probably be defined by the areal lift needed to reach the roof. A draft of the installation proceed needs revised and then the equipment at each step listed.

Main Steps are:

Installation of the detector support structure Installation of cryogenic piping, Detector installation.

I added info on the areal lift on the installation page.

  • -> Where is the info?
  • -> Who?

2. Underground space

Plan for the work flow

Understand the test required on the APA. Horizontal or Vertical.

Understand the work flow (row by row? section by section?)

  • -> Where is the info?
  • -> Who?

Ross Cage Design

Bill's proposal: docdb entry

  • -> Bill

Random information and questions

  • If we make the cage tall enough to fit the APA crate inside, the excavation equipment for CF may not fit inside because the cage reduces maximum width by ~4” (100 mm) as compared to a slung load
  • Making the cage taller also makes it heavier, reducing the weight capacity for both slung and cage loads
  • Can we do to the Yates shaft for some items? Boundary conditions.
