  1. Muon Accelerator Program m+ m- MUON COLLIDER & NEUTRINO FACTORY R&D in the U.S. n Steve Geer OsC RAL 21 June, 2010 1

  2. The MAP Initiative • Muon Collider & Neutrino Factory R&D has been pursued in the U.S. since 1996 by the Neutrino Factory & Muon Collider Collaboration (NFMCC). • The Muon Collider R&D activity was enhanced in 2006 by the addition of the Muon Collider Task Force (MCTF) at Fermilab. • In October 2009 the DOE-OHEP leadership requested a new unified national organization (MAP) be put in place, and prepare a proposal for an enhanced R&D program: • -Motivated by recent progress, and an increased interest in a multi-TeVMuon Collider as a possible future facility at Fermilab Steve Geer OsC RAL 21 June, 2010 2

  4. MAP Organization now in place “Level 0” “Level 1” “Level 2” * L0, L1, L2 Interim assignments Steve Geer OsC RAL 21 June, 2010 4

  5. MAP Proposal • ● Submitted by Pier Oddone on behalf of the MAP collaboration, 1st March 2010. • ● 214 MAP participants (at birth) from 14 institutions: • ANL, BNL, FNAL, Jlab, LBNL, ORNL, SNAL, Cornell, IIT, Princeton, UCB, UCLA, UCR, U-Miss. • ● Anticipate a DOE-OHEP review soon.

  6. MAP will pursue both Neutrino Factory & Muon Collider R&D NEUTRINOFACTORY MUONCOLLIDER In present MC baseline design, Front End is same as for NF Steve Geer OsC RAL 21 June, 2010 6

  7. R&D Common to both NF & MC (from proton driver to initial cooling channel) • Front-End Design & Simulations • - Pursued in the context of the IDS-NF • Includes site specific studies for NF/MC at FNAL, including using an upgraded Project X as the proton source (coordinator: Keith Gollwitzer) • MERIT experiment (Great success – in final analysis phase) • RF studies for cooling channel cavities operating in magnetic channels • -MuCool Test Area (MTA) program • U.S. contributions to MICE (see talks tomorrow) Steve Geer OsC RAL 21 June, 2010 7

  8. MuCool Test Area • MUCOOL Test Area built at FNAL for ionization cooling component testing: • 5T magnet • RF power at 805MHz & 201MHz • LH2 handling capability • 400MeV beam from linac Steve Geer OsC RAL 21 June, 2010 8

  9. Muon Collider Decision Tree 0.5 TeV e+e- 3 TeV e+e- 3-4 TeV m+m- Pier Oddone Steve Geer OsC RAL 21 June, 2010 9

  10. Muon Collider Motivation • If we can build a muon collider, it is an attractive multi-TeV lepton collider option because muons don’t radiate as readily as electrons (mm / me ~ 207): • - COMPACT Fits on laboratory site • - MULTI-PASS ACCELERATION • Cost Effective • - MULTIPASS COLLISIONS IN A RING (~1000 turns) Relaxed emittance requirements & hence relaxed tolerances- NARROW ENERGY SPREAD Precision scans, kinematic constraints • - TWO DETECTORS (2 IPs)-DTbunch ~ 10 ms … (e.g. 4 TeV collider) • Lots of time for readout Backgrounds don’t pile up • -(mm/me)2= ~40000 • Enhanced s-channel rates for Higgs-like particles A 4 TeV Muon Collider wouldfit on the Fermilab Site COST PHYSICS Steve Geer OsC RAL 21 June, 2010 10

  12. MAP Goals • ● Deliverables in 6-7 years: • Muon Collider Design Feasibility Report (FY16) • - Hardware R&D results → technology choice • MC Cost range (FY16) • Also contributions to the IDS-NF RDR (FY14) • ● Will address key R&D issues, including • Maximum RF gradients in magnetic field • - Magnet designs for cooling, acceltn, collider • - 6D cooling section prototype & bench test • - Full start-to-end simulations based on technologies in hand, or achievable with a specified R&D program Steve Geer OsC RAL 21 June, 2010 12

  13. Key component models Impact of the MAP Plan Muon Collider Development + NF RDR NOW MAP PLAN Steve Geer OsC RAL 21 June, 2010 13

  14. Evolution of Support Last couple of years First ~10 years NOW(FY10) FY11 NFMCC + MCTF NFMCC Interim MAP MAP ~4 M$ ~9 M$ ~10 M$ ~15 M$ (requested) (~19 M$ enhanced plan) Steve Geer OsC RAL 21 June, 2010 14

  15. Physics, Detector & Background Studies • ● In addition to MC accelerator R&D, a parallel but coordinated effort is foreseen on physics & detector studies: • Machine-Detector Interface group within MAP will generate machine background files for, and “interface” with the physics-detector activity. • - Physics-detector studies leader will participate in MAP “management council”. • ● Detailed detector & Background studies from ~10 yrs ago gave encouraging results. A lot has happened since: • New MC lattice design • - A decade of detector development • Greater community expectations for detector performance • ● New physics, detector, background studies begun: • Kick-off workshop at FNAL November 2009. • Rapid progress since then on shielding design (shielding cone angle reduced from 20deg to 10deg). • Active detector simulation group now being created. • Working towards an initial report ~mid-2011.

  16. International Aspects • ● Neutrino Factory R&D is pursued in an international framework: IDS-NF • - The MAP community is committed to making the required contributions to IDS-NF studies • ● Muon Collider R&D is pursued mostly in the U.S. • - Making it more international would be a good thing • - The MICE facility is potentially a wonderful asset for longer term Muon Collider R&D • ● Had some good initial experience with joint Fermilab-UK accelerator R&D fellowships focused on muon accelerator R&D areas: • The UK host has been Imperial College • Helps build R&D relationships in areas of common interest (e.g. MuCool RF R&D program, proton source issues, …) Steve Geer OsC RAL 21 June, 2010 16

  17. Summary • ● There is a new U.S. organization (MAP). The proposed MAP plan is designed to: • Continue support of the ongoing program (including U.S. commitments to MICE and the IDS-NF • Within the next 6-7 years find out whether a Muon Collider is feasible, and roughly what it would cost (cost range). • ● The U.S. motivation for MAP is coupled to a muon-based vision for the long-term future of Fermilab. • ● International collaboration on the R&D for these very ambitious but game-changing future accelerator facilities is very desirable • Has been very good for the NF R&D program • Would be very healthy for Muon Collider R&D Steve Geer OsC RAL 21 June, 2010 17
