Cable Update

We are starting to make some process on cable management and location of cable trays

• Matt has shipped a single set of

CE cables-We have enough “misc.” cables to mock up the

• ther bundles
• PD folks have located the

proper cable, so we could purchase it but we have to buy a 1000’ roll ($1100) so we are just going to use free CAT6 cable but constrain it in a way that uses the same bend radius

• Starting to get some cable tray

PD cable feedthrough Signal flange and warm interface crate The bottom cover plate has many slots to capture the cable bundles Can the cables be pre- installed onto the bottom cover plate in the clean room?

Cable Management Concept

Cable Management Requirements

• Cables (13.5m-10 cables) for PD system are installed first-Keep separated

from Cold Electronics cables as much as possible

• LV and Data Cables (7m-20 bundles of each type) for the cold electronics are

installed second and must be routed over or thru front of cable tray

• All cables need to be organized so that differential lengths are secured in the

cable tray and the feed-thru “umbilical” exits from the middle of the APA.

• Organize the cables to keep a balanced load to minimize any on the APA
• In the cleanroom the entire set of cables need to be held in these trays
• Trays design need to be narrow enough to make it into Cold Box
• Trays need to allow access to change out a cold electronics box if needed,

cables are pre-attached so the entire cable would also be replaced

• It is possible to have a separate tray that supports the umbilical that is located
• n the Bridge Beam once inside the cryostat to support the run to the feed-thru.
• Cables should be keep in liquid

Tray mounted to APA. “Differential” length is stored here. Tray mounted to I –beam. Length contingency is stored here. Also allows for APA plane to translate to the right 20cm on Bridge Beam E Only service length is stored in feed thru Cable tray can be used here to bridge to the feedthru

What we have at Ash River

We have a slightly different APA head tube than the final design

More Ash River Pictures

We need to confirm that the total of 219mm from the bottom of the SS beam to the top of the electronics Box is correct we seem to have more room

Cable tray should not be a problem

This should fit thru the Cold Box easily door, we may have to add the latch later

More new cable information

March 1st, 2017 13

• A cable or two connecting the

lower field cable resistor chain to the FC termination board mounted on the top if the APA should be run when the PD cables are run. They need to be isolated from the PD cables

• There are 8 lemo sized bias

cables that also run from the CE boxes back to the feed

• thru. Small but we should

understand where they run

• Bias cable: RG316 with SHV
