CLIC cost & power consumption issues

Philippe Lebrun

on behalf of theC&S WG

CLIC Meeting

11 December 2009


Main linacs are the cost drivers

CLIC 3 TeV cost estimate 2007 (H. Braun & G. Riddone)

Indirect impact

Direct

Main linacs are the cost drivers

  • The main linacs

    • account for a large fraction of CLIC cost,

    • impact strongly on other capital (tunnel, infrastructure, services) and operation (electricity, cooling, maintenance) costs

  • Very high, unprecedented number of components

    • constitute a major cost (and to some extent, feasibility) issue

    • will require novel solutions for manufacturing, installation, maintenance, reliability

Power consumption @ 3 tev new iteration k schirm nov 2009 1 2

Power consumption @ 3 TeVNew iteration (K. Schirm, Nov 2009)[1/2]

  • AC power distribution & conversion on site

    • Apply h = 0.9 throughout

  • RF power flow

    • First iteration (C&S WG of 091126) shows substantial increase

    • Identified: increased pulse length in DB linacs, lower modulator efficiency

      ⇒ Check efficiency values applied throughout RF chain, grid-to-beam

  • Magnets

    • Large increase in power of many magnet systems due to increase in

      • Aperture (MB quads, DB turnarounds, DB quads)

      • Field strength (DB quads)

      • Current density (MB quads, DB quads)

        ⇒ Track « hidden » safety factors in beam physics requirements

        ⇒ Impose power limit/low current density to magnet designers (with additional benefit of indirect water cooling of coils)

        ⇒ Review DB quad powering scheme

Power consumption @ 3 tev new iteration k schirm nov 2009 2 2

Power consumption @ 3 TeVNew iteration (K. Schirm, Nov 2009)[2/2]

  • Instrumentation

    • Large increase in power: number of channels

    • Particularly damaging as power is dissipated in HVAC system

      ⇒ Innovative solutions for readout electronics, data transmission, cabling

  • Infrastructure & services

    • Not yet reviewed

    • Previous values taken as percentage of installed capacity (H.B.)

  • Experimental area

    • Previous value taken from CMS (H.B.)

      ⇒ Input needed from physics & detector WG

      ⇒ Work in progress, to be followed early 2010

      ⇒ Different estimates required for different purposes

    • Overall efficiency comparison with ILC (@ 500 GeV)

    • Sizing of AC power distribution

    • Sizing of water cooling & HVAC systems

    • Operational cost

Summary

Summary

  • Cost consciousness well established in CLIC technical working groups

  • Cost drivers and cost reduction areas identified - as well as their interplay - analysis not yet exhaustive

  • Analytical costing exercise under way by domain coordinators with input from technical system experts, in domains where technical baseline exists

  • Cost studies by industrial companies, in particular for large-series components, useful for substantiating cost estimate

  • New iteration of power consumption estimate started

  • Feedback on cost and power provided to technical system design

  • Cost and power consumption can only be finalized after freeze of configuration for CDR
