DUNE Installation

  • Define Requirements for Underground Installation
  • Define detector components and identify space
  • Assumptions and requirements of detector crates
  • Description of present concept of detector

assembly and installation

  • Work in the toaster area

Weekly Installation Goal to Meet Current Schedule

Components will be moved into the Clean Room in sufficient quantities to assemble & install ‘one set’

  • f panels as shown. A.k.a. ‘ 1/25TH assembly.

Facility Requirements

  • Crane
  • Need 6.5m hook height to install 4m long CPA with rigging.
  • Need 6m hook height to remove APA’s vertical out of crate
  • Need two hoists that can transverse North-South to rotate

APA’s. Dual hoists need to be able to get within 1m of each

  • ther
  • Need north-south coverage for 2-3 work stations
  • Need class 100,000 “Gray Room” (Could be achieved

with Uni-Strut Frame and plastic sheeting)

  • Need storage space for 1 week of installation

underground

  • Crates need to be stored within the foot print of crane

coverage

Facility & Components

Anode Panel Assembly (APA) ~12 m tall Cathode Panel Assembly (CPA) ~12 m tall Field Cage (FC) Upper Assembly Area a.k.a. ‘Pedestal’ Lower Assembly Area a.k.a. ‘Toaster’ Some features and / or components may or may not be shown on subsequent slides for clarity. Clean Room Boundary Cryostat Access Door Gantry Crane Footbridge Person Person Clean Room Boundary

Gantry Crane

  • Gantry will run East-West on fixed rails and cover pedestal and

cryostat.

  • Two 3 tons hoists with dual speeds for smooth motion
  • Hoists and gantry will be driven
  • Meets requirements for coverages
  • $68k Dearborn Crane
  • 15fpm hoist speed so ~3m from pedestal to pit floor

Crates

  • Crates need to be able to be rotated

180 degrees and hung from ends – challenge for crate design

  • Max Crate Loads
  • Height – 3.6m
  • Depth – 3.7m
  • Width – 1.38m
  • Weight 13,00lbs
  • Crates will be transported to cavern on

carts 18” high.

  • Wooden crates not allowed in

cleanroom

  • North drift needed to remove outer

shell of crates?

Assumed APA and FCA Crate Sizes and Capacity

APA – one complete panel per shipping container, shipped in ~6m sections CPA – one complete panel per shipping container, shipped in ~4m sections Middle Upper 1/3 panel Lower 1/3 panel Upper 1/3 panel Crate covers not shown

Assumed FC Crate Size and Capacity

FC – two complete panels per shipping container Upper panels packaged ‘hinges UP’ Lower panels shipped ‘hinges DOWN’. FC Crate has an inner structure to support the FC. Top and sides removed tor loading & unloading of FCs Loaded Crate (top not shown)

Detector Assembly and Installation

  • APA’s
  • 2 APA’s per crate
  • Top and bottom APA’s installed using a fixture that holds

APA’s for cable routing and physical connection

  • Assume PD and electronic boxes are installed and no

cables are connected.

  • Minimal testing after APA pair assembled
  • CPA’s
  • Three CPA modules that are 4m long are connected

using a fixture.

  • FC modules attached to CPA pair in toaster

APA UNPACKING & CONSTRUCTION

1) Half (~6m) of APA removed from crate 4) Lowered into Assembly fixture 3) Rotated to align with assembly fixture 2) Rotated to stand vertically

APA crates are not designed so assuming vertical lift out of crate

CPA UNPACKING & ASSEMBLY

1 - Boxed CPA in

  • position. 1/3 panel

being raised from crate 2 - CPA panel being lowered into Toaster 3 - CPA panels (6 x 1/3) Assembled at bottom of Toaster

SLIDE 18

Work in the Toaster

  • Work in toaster very constrained due to cryo

towers

  • Access is needed on both sides of APA/CPA during

installation.

  • HV and APA Consortium need to define what work

needs to be done in toaster after mechanical assembly.

  • Need fixtures for assembling APA and CPA into full

height and then transfer to TCO beam

  • We don’t want to work with APA/CPA on TCO beam

because it blocks access to the cryostat

  • Four Options for Toaster work considered
