SLAC ACCELERATOR RESEARCH AND EXPERIMENTS COMMITTEE (SAREC)

The Accelerator Research Division (ARD) at the SLAC National Accelerator Laboratory manages a strong R&D program in Accelerator Science and Technology. As part of this program, ARD operates or will operate a number of facilities for experimental accelerator research including the NLC Test Accelerator (NLCTA), the Accelerator Structure Test Area (ASTA), and the new beamlines at the Facility for Advanced Accelerator Experimental Tests (FACET) and the End Station Test Beam (ESTB). The NLCTA and ASTA facilities largely support the in-house R&D programs although some external proposals can be considered. The new FACET beamline is expected to support an external user-driven program with priority given to wakefield-driven beam acceleration experiments. FACET will start delivering beam to users by the middle of 2011 and SLAC is soliciting and considering proposals now. The ESTB facility, located in End Station A, will be constructed in 2011 and will be soliciting proposals early next year.

The charge of the SAREC committee is to:

 evaluate the merit of proposed R&D in SLAC’s experimental accelerator research facilities for advancing world-class accelerator science or accelerator technology

 evaluate the feasibility of proposed R&D in SLAC’s accelerator research facilities

 review the progress of existing R&D in SLAC’s accelerator research facilities

The committee will report to the Head of the SLAC Accelerator Research Division and is expected to meet once per year. The committee will be supported with ad hoc consultants as necessary. The proposals will have been looked at by an internal committee to estimate issues associated with mounting the experiments and this information will be available to SAREC.

The current FACET proposals should be evaluated for the pre-CD4 commissioning run during the summer of 2011 which will be roughly two months but will have limited access as well as the first scheduled FACET run in 2012.

The specific charge for the January, 2011 meeting is to:  Evaluate the scientific merit of the proposals for the commissioning run of the FACET facility during the summer of 2011 and rate the technical risk of the proposals. Determine whether the proposal would be appropriate for the commissioning run during the summer of 2011 before the completion of the FACET construction project  Assess opportunities for additional collaborations and/or external user proposals  Comment on the initial FACET operational scenarios  Comment on the focus of broader SLAC ARD experimental program and suggest opportunities for additional collaboration or external user engagement

The proposals should be rated using the following rating scale: 1 - Excellent 2 - Very Good 3 - Good 4 -- Fair 5 - Not well suited

The rating should be based on:

 the scientific merit of the proposal, assuming successful execution,  the technical risk associated with the detailed measurements and requested beamparameters, and,  the suitability of the experiment for the FACET facility in terms of beam energy, bunch length, beam emittances, etc.

The reviewers should note if they feel that the experiment could be more reasonably performed at an alternate facility.

As noted, the proposals have been initially scanned by an internal committee looking to make sure the proposals are complete and self-consistent. In certain cases, supplemental information has been requested. If additional information is still needed for a full evaluation, the review committee should note this and may make a qualified rating or may skip the review if appropriate.
