  1. FY 09 AES Phase I Crab Cavity SBIRs Michael Cole, Doug Holmes

  2. SBIR Program Format • Phased Program • Phases Awarded Independently • Phase One Starting July 09 (in neg. now) • 8-9 Months • Limited Program • 500 Hours (13 Man Weeks) • Feasibility Study • Costing Study for Phase Two • Awards mid to late April • Phase Two • Based on successful Phase One, Late Summer 2010 Award. • Phase Two is proposed via Phase One report. • Two year program $750K max Level Funded • Year two technically optional for DOE • Detailed Design, Hardware, and Test phase

  3. Submitted SBIRs • The Crab Cavity: AES (Cole), BNL, LBL, and SLAC • Couplers for the Crab Cavity including LOM, SOM, HOM, and FP: AES (Cole), BNL, LBL, and SLAC • A Cryostat for use with the Crab Cavity: AES (Holmes) and FNAL • Crab Cavity Tuning Devices: AES (Holmes) and FNAL • Of these we only won the first, the Crab Cavity SBIR.

  4. Impact • Only have funding for engineering and analysis of Cavity. • Effort on potentially complex coupler structures will have to come from elsewhere. • Same for Cryostat and Tuner development.

  5. Prototype Crab Cavity • Collaborators are AES, BNL, LBL, and SLAC • Phase 1 • Preliminary Design of Cavity (3 man months supported by SBIR) • Coordinate transfer of Physics Design • Develop initial mechanical solid model • Perform Initial Thermal and Structural Analysis • Preliminary Mechanical Design and Fabrication Feasibility Study • Phase 2 • Complete mechanical design with supporting thermal/structural analysis. • Generate complete fabrication drawing package for the Crab Cavity. • Fabricate Prototype Crab Cavity • Perform BCP and HPR on Prototype Crab Cavity at AES if our facilities can accommodate it. We anticipate that we will be able accommodate an 800 MHz elliptical crab cavity. • Support Crab Cavity VTF testing at BNL

  6. Crab Cavity Couplers • Focus of the coupler SBIR was to have been the coupler structures. • The boundary between the cavity and couplers is quite blurry for some of the configurations. • It is reasonable to expect that provisions can be made to retrofit couplers at a later date.

  7. Cryostat • Effort required to look at retrofitting cavity to some existing cryostat will have to come from elsewhere. • This program can support some of this but it will be at the expense of the cavity work. • Best results will be from external support of cryostat engineering. • We will provide models and drawings of the cavity.
