Installation and Integration/ActionItems

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

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

• -> 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.
