Linear Collider R&D Proposals
· Last spring, following the release of the HEPAP report, the US community began developing plans for an invigorated R&D program and proposals to the funding agencies · Organizational meetings were held at Fermilab, Cornell, and SLAC
­ ALCPG working groups led discussions on R&D opportunities ­ eventually the DOE groups consolidated into the LCRD and the NSF groups into the UCLC

· The US Linear Collider Steering Group developed a plan on how to deal with these proposals:
­ create a review committee ­ have the proposals reviewed at the project level

· The funding agencies responded to the ground-swell of interest within the community and developed a plan for the scope of the program
Jim Brau, Arlington, January 9, 2003

Linear Collider Accelerator R&D
· Many in the American university community expressed their interested in linear collider accelerator R&D · In response to this, the LC accelerator physicists prepared a list of R&D projects and the community developed proposals to address some
http://www-conf.slac.stanford. edu/lcprojectlist/projectlist/intro.htm

· 33 accelerator project proposals were submitted as part of the final University Program proposal on October 24

The Internal Review and Proposal Development
· At the Santa Cruz ALCPG meeting in June there was much discussion on how to proceed to proposals · Coming out of that meeting, there was an agreement from both the NSF(UCLC) and DOE(LCRD) groups to ­ submit Expressions of Interest by August 1 ­ Expressions of Interest were reviewed by the ALCPG working group leaders by August 6, providing criticism and recommended revisions ­ Proposals were collected by September 3 · The LCRD and the UCLC joined into a single national coordinated document to the US LC Steering Group

US R&D Proposals
· The single, combined proposal which was developed over the summer became:
A University Program of Accelerator and Detector Research for the Linear Collider

­ about 2 M$ first year (increasing in subsequent years) ­ very strong accelerator R&D component
· (roughly 1/2 of total funding)

· International Detector R&D Committee report provided guidance for detector projects

(for the Detector Review Team)
The success of the Linear Collider physics program depends on optimizing the accelerator technology, and capitalizing with optimal detectors on the opportunity afforded by machine performance. While much progress in detector development has been made in recent years, especially through R&D for the LHC, different optimizations are needed for the Linear Collider experiments. There is time now to develop these technologies, and to discover and pursue new ideas which can further enhance the physics reach. With this in mind, the Linear Collider R&D Review Committee is charged to * Prioritize the elements of the proposals in the light of the R&D needs of the worldwide linear collider effort. Considerations entering into the prioritization should include the relevance and importance of the work to the perceived needs of the Linear Collider detectors, the lead-time requirements for the proposed R&D, and the experience and track record of the proposers . Novel ideas which have potential to impact the detector designs significantly should be identified with favor. * Co-ordinate the elements of the proposals by identifying areas of overlap, within a single consortium proposal, between the proposals, and within the international R&D program. Suggest possible realignments of the efforts which would eliminate unnecessary redundancy. The committee should refer to the document "Linear Collider Detector R&D" by the international linear collider detector R&D committee chaired by R. Heuer.

The Charge

13


(for the Detector Review Team)
There is additional guidance (besides the charge) from the Steering Group on what they would like coming from this review. They would like you to provide: 1.) a rating for each proposal (e.g. excellent, good, satisfactory, or poor) based on factors such as clarity of goals, feasibility, strength of the participants, etc; 2.) a categorization of the relevance of each proposal (e.g. critical R&D, important R&D, useful R&D, or irrelevant); 3.) and a rank-ordering of the proposals. This rank-ordering likely will be a grouping of the proposals into tiers (e.g. first priority, second priority, defer, or drop). You may need to indicate why you recommend to drop a proposal, but everyone recognizes you will not have time to write much verbiage. Please keep an eye on the total cost of the proposals. The budgets are not certain, but the guidance is that the Funding Agencies will try to provide a growing total of approximately 1M$ in FY03, 2M$ in FY04, and 3M$ in FY05 for university-based detector R&D. You will not need to worry about whether the funds are DOE or NSF. So for example, the first tier would be a mixture of "excellent" and "good" proposals that sum to approximately 1M$ in FY03 and are aimed at "critical", "important", or "useful" R&D goals. Since the funding is uncertain, the second tier will also be important, and should not consist of just every proposal that does not make it into the first tier.
