  8. Scope of the 500 GeV machine • Main linacs length ~ 21 km, 16,000 RF cavities (total) • RF power ~ 640 10-MW klystrons and modulators (total) • Cryoplants ~ 11 plants, cooling power 24 kW (@4K) each • Beam delivery length ~ 5 km, ~ 500 magnets (per IR) • Damping ring circumference ~ 6.6 km, ~400 magnets (each) • Beam power ~ 22 MW total • Site power ~ 200 MW total • Site footprint length ~ 47 km (for option to future upgrade to 1 TeV) • Bunch profile at IP ~ 500 x 6 nm, 300 microns long DOE/NSF ILC Program Review

  9. Accelerator physics and engineering challenges • Developing efficient high gradient superconducting RF systems • Requires efficient RF systems, capable of accelerating high power beams (~MW). • Achieving nm scale high-power beam spots • Requires generating high intensity beams of electrons and positrons • Damping the beams to ultra-low emittance in damping rings • Transporting the beams to the collision point without significant emittance growth or uncontrolled beam jitter • Cleanly dumping the used beams. DOE/NSF ILC Program Review

  10. Affordability challenges Civil Pie chart From US Tech. Options Study SCRF Linac DOE/NSF ILC Program Review

  11. ILC Baseline configuration Document (BCD) • – A baseline configuration for the ILC machine, with a conceptual layout, and beam parameters, was defined at end of 2005. • The baseline made forward looking choices, consistent with attaining performance goals. The choices were understood well enough to do a conceptual design and reliable costing by end of 2006. • “Alternate” configurations were established, which may have cost and or performance benefits, but which need further R&D for validation. • - The baseline is under “configuration control,”with a defined process for changes to the baseline. DOE/NSF ILC Program Review

  12. ILC Baseline Configuration • Configuration for 500 GeV machine with expandability to 1 TeV • Some details (locations of low energy acceleration, crossing angles) are not indicated in this cartoon. • Tor Raubenheimer will present more details on the BCD DOE/NSF ILC Program Review

  13. ILC Reference Design Report (RDR) and Cost Estimate • Based on the Baseline Configuration, a reference design and cost estimate will be carried out in 2006. Technical performance and physics performance will be evaluated for the reference design report. • This process began after the Frascati GDE meeting and will conclude late in 2006. • This is a global effort, with participants from all three regions. • Tor Raubenheimer will describe the RDR process in more detail. DOE/NSF ILC Program Review

  15. ILC Value estimate • The ILC will be built as an international joint project, in which the three regions will contribute mainly “in kind” (specific components) • Cost estimates must be done in the context of the in-kind contribution model. We will need to secure regional component cost estimates and evaluate these in terms of a globally defined value unit. (ILC unit) • The complete value estimate will be translatable into a given region’s currency and cost estimating methodology. • Peter Garbincius will describe the plans and methodology for the value estimate in more detail. DOE/NSF ILC Program Review

  16. ILC Program Execution In the Americas region, the ILC program (the RDR effort, and supporting ILC R&D), is executed by the Americas Regional Team.

  17. Organization of the ILC-Americas Program • The work is broken down into a series of technically-based work packages. • GDE and each DoE lab sign MoU’s detailing the co-operative arrangement for the execution of work packages at each lab. • Yearly scope of work is spelled out in Addenda to the MoU, which detail the work packages. • For university R&D work, each university project is a work package. • Labs report financial status at the work package level quarterly, and technical status semi-annually. (Actuals not yet available for FY06 for all work packages. Some actuals will be covered in presentations) • About 100 work packages for FY06 are organized into a WBS. • The list of work packages, and associated resources, as well as the MOU Addenda, are posted on the ILC-Americas web site: https://wiki.lepp.cornell.edu/ilc/bin/view/Public/Americas/WebHome DOE/NSF ILC Program Review

  39. TRIUMF Potential TRIUMF Accelerator R&D Resources for ILC The specific nature of Canadian involvement is under development. Some potential collaboration areas have been identified, along with relevant LHC experience: • The design of kicker magnets and the construction of associated pulse-forming networks and fast switches using power semiconductors • Precision room temperature magnet systems e.g. 52 twin-aperture quadrupoles built at Alstom Canada • Beam instrumentation and readout systems e.g. 2000 matched-pair 70MHz low pass filters e.g. VME64x compliant Digital Aquisition Board (DAB) • Contributions to beam dynamics & lattice calculations for damping rings.

  40. TRIUMF • Building on expertise developed for TRIUMF ISAC radioactive beams accelerator, additional possible areas are: • Remote handling design/consulting of target stations possible applicability to conventional positron source • Peripheral aspects of superconducting r.f., such as cryogenic coolant distribution system, design/consulting, small quantity e-beam welding of niobium UBC -Tom Mattison Vibration control systems and alignment of components for final focus system; also interest in abort kickers DOE/NSF ILC Program Review

  41. FY06 program concerns • Do we have sufficient resources available to complete the RDR and cost estimate? Some funds have been held in reserve to pay for additional help, but also we will need to divert some effort from R&D program. • Key R&D concerns: • Development of reliable high-yield processes for the production of high-gradient ILC cavities remains a critical item. Cavity fabrication and studies of processing are high priority parts of the program. • Thales klystron problems emphasize need to put more effort into klystron development. Difficult to do this before FY07. • Additional efforts are needed to co-ordinate Americas R&D program and to plan for the future, both within the region, and with programs in other regions. DOE/NSF ILC Program Review

  42. FY07 outlook • PB doubles ILC program budget to $60M (This includes ILC detector R&D at labs and universities) • However, the requested (“technically limited”) program exceeds the available funding. A process of prioritization will be required. • This process should look to GDE for guidance on priorities. Advice will be sought from GDE R&D Board for general ILC R&D efforts, and from Linear Collider Steering Group for the Americas (LCSGA) for region-specific Americas bid-to-host related activities. • First steps: document FY07 lab program requests (April 26); Regional team meeting to discuss FY07 requests and future plans (May 3-4, SLAC) DOE/NSF ILC Program Review
