description



Status of analytical cost estimates

• CLIC Study Costing Tool– Operational– Based on PBS for CLIC 3 TeV and 500 GeV, as defined by TC for the CDR⇒ analytical cost upload just started

• Questionnaire sent to Domain/Subdomain Coordinators (3 August 2009)– Preparation of analytical cost estimate review– Identification of cost drivers, risks and reduction issues⇒ one received so far!

• Presentations at C&S WG meetings– 24 September 2009: Main beam production - damping rings (Y.

Papaphilippou)– 29 October 2009: Drive beam production (B. Jeanneret), Two-beam

accelerator modules (G. Riddone)– 5 November 2009: Infrastructure & services (J. Osborne)– 26 November 2009: Main beam production - injectors & beam transport

(L. Rinolfi), [Interaction region (L. Gatignon)]⇒ work in progress⇒ technical definition for analytical costing not available for all

domains/subdomains



Main linacs are the cost drivers

• The main linacs account for a large fraction of CLIC cost, and impact strongly on other capital (tunnel, infrastructure, services) and operation (electricity, cooling, maintenance) costs

• Very high, unprecedented multiplicity of components, will require novel solutions for manufacturing, installation, maintenance, reliability assessment

Summary

• Cost consciousness well established in CLIC technical working groups (Module, RF structures, CES,…)

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

• Cost scaling models only exist for limited number of components or subsystems

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

• Technical baseline to be defined in other domains • Significant differences observed w r to 2007 cost estimate• Feedback provided to technical system design• Targeted cost studies by industrial companies considered, in

particular for large-series components• Reliability/availability assessment to be conducted (TC?) for system

design and possible cost impact
