Project X: Reference Design Report Plan

1. Project X: Reference Design Report Plan Steve HolmesProject X Collaboration MeetingNovember 28, 2012

2. Goals • Reference Design Report released November 201 http://projectx-docdb.fnal.gov/cgi-bin/ShowDocument?docid=776 • Known deficiencies of current release: • 325 MHz RFQ • 325 MHz SSR0 • No staging strategy • No description of experimental facilities • Goal: New release of RDR describing current configuration prior to Snowmass 2013 • Consistent with staging strategy • Reviewed by the Project X Machine Advisory Committee (XMAC) • One volum,e of the four volume set PX Collaboration Meeting, Nov 2012 - S. Holmes

3. Goals • Scope/Configuration • 3 GeV, CW, H- linac • 2 mA of beam to 1 GeV; 1 mA from 1-3 GeV • 3-8 GeV pulsed, H- linac with 4.3% duty factor. • Upgradable to 10 mA @ 5% duty factor, including the connecting arcs • Required improvements to the MI/RR • Experimental facilities required to deliver beams to experiments • 230 MeV, 1 GeV, and 3 GeV extraction • Siting consistent with a staged approach (”paperclip”) • Staging will be described in an appendix, including modifications to Booster and Muon Campus for Stage 1 • Possible performance enhancements (high power at 8 GeV, accumulator rings at 1, 3, or 8 GeV) will be described in an appendix.
