Weekly DUNE SP Detector Integration Engineering Meeting Slides

• Alternate cable tray

95% Fill and Cable Tray Height

• Can the cable tray be

modified to achieve a lower position relative to the 95% fill line?

• The outcomes could

result in compete cable tray submersion

95% Fill Line

Use exactly 6 degrees not 6.01

Top Latch and Field Cage Rotation

Top Latch to Cable Tray

• No interference with cable tray

uni‐strut when top latch is rotated up 6.0°

• Top latch to uni‐strut contact

will be made when latch is rotated 29° above horizontal

• This amount of rotation is

unlikely with FC deployment method

Cable tray to Corrugations

• 42mm clearance from cable

tray to corrugations (two sides of TPC)

Options for Lowering Cable Tray

• Moves into the cryostat

mounted to the APA yoke

• Mounting brackets

removed and trays suspended

• Suspension points

variable

• Constructed of formed

sheet metal

• 10ga stainless steel

Continued: Options for Lowering Cable Tray

• Tray is lower by

29mm

• Tray is wider by

30mm

• APA trolley info

unavailable

95% Fill Line 96% Fill Line Top of Yoke

Continued: Options for Lowering Cable Tray

• Clearance for 6.0°

latch rotation (but not much more)

Continued: Options for Lowering Cable Tray

• More analysis and

refinement is worthwhile
