WIP Surface Site Descriptions for CE Design and Costing PA

FCC-ee project element descriptions PA

Experiment site PA

This site features underground experiment caverns that host the particle detectors.

The surface site facilities serve on one side the assembly and operation of those underground detectors and on the other side provide critical resources to the particle accelerator.

This site candidate is subject to strong environmental and urbanistic constraints and must therefore be kept as small as possible. In particular, building heights must be kept low - ideally below the height of the supermarked in the west of the site.

The site shall be considered differently during the construciton and the operation phases in order to optimise the space needs.

The minimum required surface site construction elements during detector installation and possibly during the operation phase are:

  • An experiment assembly hall that may need to be removed or substantially modified as soon as the experiment is installed.
  • A shaft head building for the service cavern access
  • A shaft head for the experiment installation shaft
  • A building for compressed air
  • A building for the experiment gas supply
  • A building for electronic racks that need to be kept as close as possible to the access shafts
  • A ventilation station
  • A pumping station with chillers
  • A cooling plant
  • A storage area that might be integrated in the experiment assembly hall after the experiment is installed
  • An access building, potentially integrating in the same building offices and meeting rooms
  • Radiological buffer and clearance
  • An area for equipment handling and turning
The following elements may potentially be moved to the LHC Pt8 site or a new area in the south of the LHC Pt8 site, reachable by the road in the east of the supermarked:
  • Cryo-plant for the experiment
  • Power converters that cannot be placed underground
  • Cooling towers
  • Water reject treatment
  • A retention basin
  • An electrical substation with a footprint between 0.5 ha (63 kV) to 1.5 ha (225 kV).

Purpose

This page is intended to be used for the development of Surface Site Layouts and preliminary building designs and costing for the FCC Feasibility Study only.

Design and Costing will be based on FCC-ee only. FCC-hh requirements will be considered for spatial purpose only.

The following table summarises the key elements on the surface.
