The US 5 Year Muon Acceleration R&D

Program

To Boldly Go…MICE Collaboration Meeting

HarbinJanuary, 2009

Overview

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

The 5 Year PlanThe 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

Elements of the Plan - 2

• Design and Simulations – MC DFS

• Physics and Detector Study (Demarteau and Eichten)

• Accelerator Design & Simulation Study (Ankenbrandt & Fernow)

• Cost Estimation Study (Zisman)

– NF RDR (Bross) (under IDS-NF auspices)• Overall system design and staging scenarios • Siting issues• Participation in cost estimation activity

Page 6MICE CM – Harbin January 2009 A. 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)

Why Muon Acceleration R&D?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

ACTIVITIES: YEARS 1 - 2

• MC-ZDR Physics & Detector– Establish physics reach vs E & L– Define performance goals (E, L, … )– Set up background & detector simulations– Define detector requirements & plan detector R&D to inform ZDR

• MC-ZDR Design & Simulations– Study alternatives for the accelerator subsystems using

defensible parameters– Cross-check promising subsystems with 2 simulation codes

• NF-RDR Studies– Determine relevant underground conditions at FNAL– Detector magnetization design & procurement for test– Interim NF-RDR report in 2010

• Components & Experiments– MICE: Complete Steps III – V (1 RF section + 2 absorbers)– RF in magnetic field studies: Determine viable options &

performance– HCC: 4-coil models (2009) & conceptual design + short demo HCC

magnet (2010)– Other magnets (ring, fast-ramping): Study options, define parameters

Page 13MICE CM – Harbin January 2009 A. Bross

ACTIVITIES: YEAR 3

• MC-ZDR Physics & Detector– Detector R&D, simulation & physics studies– Establish likely MC detector performance

• MC-ZDR Design & Simulations– Specify baseline accelerator design & study optimization (minimize

work on alternatives)– Simulate representative matching sections– Carry out representative tolerance studies– Freeze accelerator design

• NF-RDR Studies– Underground engineering: begin cost, schedule, risk analysis– Build detector test magnet

• Components & Experiments– MICE: Complete Last step – VI (2 RF sections + 3 absorbers)– Study 6D cooling experiment options– HCC-Section: Engineering design & procurement (magnet+RF)– Guggenheim-Section: RF Cavity and magnet conceptual

design– Other magnets (ring, fast-ramping): Define technology tests to inform

ZDR

Page 14MICE CM – Harbin January 2009 A. Bross

ACTIVITIES: YEAR 4 & 5

• MC-ZDR Physics & Detector– Continue detector R&D– Compare simulated physics reach with other machines (e.g.

CLIC) • MC-ZDR Design & Simulations (& cost)

– Complete design of all matching sections– End-to-end simulation of accelerator complex– Detailed tolerance studies– Cost estimate

• NF-RDR Studies– Complete RDR report

• Components & Experiments– MICE: Simple 6D cooling experiment (LiH wedge ?)– 6D Cooling experiment design studies to inform decision about what

to propose– HCC Section: Magnet test & RF integration & test– Guggenheim-Section: Engineering design & procurement

(magnet+RF) … build & test in year 5-6– Other magnets (ring, fast-ramping): Technology tests to inform ZDR

& post-ZDR R&D needs

NICE (Next Ionization Cooling Experiment)6D Cooling Experiment

• There is no 6D Cooling Experiment in the 5 Year plan. 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 + LH2)– PIC-REMEX– Low- Bucked-Coil Lattice– Li Lens Channel

FINAL COOLING

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!
