1. The categories for ILC budget planning are: R&D – work done in laboratories to develop and verify subsystem components. This supports the cost reduction of the ILC by developing new cheaper alternatives, and reduces the risk of the design and mitigates the potential for cost overruns and stretchout. Bid to host – needed to develop the US site geology, environmental impact, infrastructure impact, buildings, shafts etc. Test facilities – infrastructure for testing superconducting rf components with beam in Laboratories. The facilities are used to test early industrial prototypes and to develop new cost saving steps in superconducting rf fabrication. Industrialization – funds needed to bring US industry up to capability to produce quality cavities, cryomodules, couplers etc with good efficiency, reproducibility and quality. Detectors – funds for experimental detector R&D and test beams Management – the US portion of ILC management costs during the R&D phase.

2. Request This request is based on a FY12 start of construction. The spending in FY11 is for the final design preparation and preparation of industry and labs for production. Results from the LHC in FY10 and beyond are required for an international agreement to proceed.

8. The OMB profile for FY07– FY11 gives 80% of the OHEP request. The reductions in the major categories are: R&D: 76% Test facilities: 100% Industrialization: 79% Detector R&D70% Impacts: Comparison of the total and integrated profiles indicates start of construction is delayed 1 year to FY2013. The reduction of R&D allows for fewer cost saving studies, so tends to increase the TPC. It also increases the chance that unforeseen surprises arise during construction causing delay and cost overruns. This in turn increases the risk that the construction phase is stretched beyond the target of 8 years.

9. Industrialization work needed to demonstrate the cost estimate and ILC feasibility are shifted to FY12. Test facilities are delayed in OMB budget, but nearly completed in FY11 to match the final industrialization funding. The delay in developing US industrial capability jeopardizes the credibility of the US bid to host. Reduced detector R&D will impair demonstration of needed new technology, resulting in less capable detectors and longer operation time to achieve comparable precision measurements.
