The US 5 Year Muon Acceleration R&D Program To Boldly Go… MICE Collaboration Meeting Harbin January, 2009

Overview Much of this comes out of the DOE Review of Accelerator Science, December 2008

Page 3 MICE CM – Harbin January 2009 A. Bross The 5 Year Plan The Proposal Has now been submitted to DOE A joint US: NFMCC-MCTF Plan –A measured program based on the solid muon accelerator R&D achievements of the last decade –Sufficiently ambitious to make substantial progress before the next round of long-term decisions by the particle physics community (Note: Coming soon – March 2009 DOE Retreat) –Includes accelerator, physics & detector studies (only accelerator part in this talk – we also have plans & estimates for physics & detector studies) Meets our existing commitments (NF-RDR, MICE) and in addition will deliver: –MC performance requirements based on physics –A first end-to-end MC simulation –Critical component development & proof-of-principle experiments –A first MC cost estimate

Bross Elements of the Plan - 3 Component Development and Experiments –Carry out hardware development and perform experimental tests to “inform” MC DFS and NF RDR Complete MICE! Facilitate down-selection of MC cooling channel options –Includes ongoing work RF testing, magnet development, absorbers, target –Understand performance limits, engineering issues, costs –Defines subsequent experimental program (extends beyond 5-yr plan)

Muon Complex Evolution At Fermilab Starting with a high-intensity proton source: Project X We see a natural evolution of “muon” program for Fermilab Project X  Low-Energy NF (pointing to Homestake)  High-Energy NF  1.5 TeV MC  4 TeV MC

A 6D cooling experiment would be a follow-on to the 5 Year plan AFTER technology down-select –A MICE extension using LiH wedge is in the plan.  Natural extension of our current LiH procurement effort 6D Cooling in the 5 Year Plan – “The bulk of the muon cooling is done in the 6D cooling channels” Proposed effort is component R&D to define specifications & conceptual design –Guggenheim –HCC –FOFO Snake –50T HTS Channel (Very-High B + LH 2 ) –PIC-REMEX –Low-  Bucked-Coil Lattice –Li Lens Channel FINAL COOLING

Bross Conclusions An overview of our proposal was presented at the DOE review of Accelerator Science in December, 2008 The full proposal has now been submitted to DOE –(No feedback yet) –Will undoubtedly be discussed at the DOE Program retreat in March (for out-years, beyond FY09) –No 6D Cooling experiment is in this proposal A FULL review of the proposal will occur at some future date –SOON we hope!
