Work package: Frames and Infrastructure

We have currently no project engineer who coordinates the various design tasks and activities. The progress and issues are being discussed in the weekly "SciFi engineering and integration" meeting, chaired by Blake Leverington. Project Leader and deputy are attending these meetings.

Scope

The work package comprises the following main items and tasks

  • C-frame mechanics, incl. rails, carriages.
  • Novec cooling and circulation plant for cooling the SiPM arrays to -40 C.
  • Water cooling system to evacuate the dissipated heat of the front-end electronics.
  • A vacuum system for the insulation of the Novec distribution lines and 0n-detector Novec manifolds
  • A dry gas flushing system to ensure a condensation and frost free environment inside the cold boxes.

Water Cooling

The heat dissipated by the front-end electronics will be removed by a circulation system based on demineralised water. The prel. requirements of the cooling plant are described in EDMS 1887449.

A row of 5 (or 6) Front-End Boxes (FEB), housing the electronics, will be serially circulated by water. Each FEB will be mounted on a cooling block which ensures the thermal contact between the cooling water and the cooling plate, which constitutes the back of the FEB.

A number of prototype cooling blocks and interface types are being tried out:

  • AAVID brazed cooling blocks with barbed fittings, connected by EPDM hose.
    • 6 cooling blocks for vertical modules mounted on bottom mounting plate.
    • 6 cooling blocks for tilted modules mounted on bottom mounting plate.
  • AAVID 2 parts cooling blocks, to squeeze a continuous 3-meter long copper tube.
    • 6 cooling blocks for vertical modules mounted on top mounting plate (as an option).
  • AMD (French local machining company) 2 parts cooling blocks, to squeeze a continuous 3-meter long copper tube.
    • 6 cooling blocks for vertical modules mounted on top mounting plate.
    • 6 cooling blocks for tilted modules mounted on top mounting plate.
