f Main points of the Report: Muon ColliderMain points of the Report: Muon Collider

Muon Collider: In contrast to the electron and hadron colliders, demonstrating the viability of a muon collider will require many steps: exploration of various possible overall schemes, a specialized proton driver, various targeting and capture and phase rotation schemes, various possible six-dimensional (6D) ionization cooling

configurations, various methods of acceleration to high energy of the cooled muons, storage ring designs and detector configurations.

Each of these steps may involve development of more than one technology. Given the many unknowns, it is not possible to predict with confidence when these explorations could be complete. In a technically limited schedule, the overall result would be paced by the 6D cooling exploration. Significant trial of the current ideas could be in hand on the five-to-ten year time scale.


f Main points of the Report (cont.)Main points of the Report (cont.)

Current Activities: international MERIT experiment at CERN and MICE at RAL Neutrino Factory and Muon Collider Collaboration (NFMCC) Muon Collider Task Force at Fermilab

Schedule and Cost: significant evaluation of cooling and other feasibility items might be carried out in approximately five to seven years given support for a technically limited schedule. A rough comparison with the U.S. ILC development intensity prior to the ITRP decision would indicate the need for a minimum of $20M annually and 100 FTE of appropriate skills.

It would be very advantageous to have more than one muon test facility where cooling and the associated technologies can be carried out…

f Muon Collider Task ForceMuon Collider Task Force Formed in July’06 by FNAL Director:

“… the Muon Collider represents a possible long term path for extending the energy frontier in lepton collisions beyond 1 TeV…”

MCTF formed “…to develop a plan for an advanced R&D program aimed at the technologies required to support the long term prospects of a Muon Collider…”

leaders: S.Geer and V.ShiltsevSept’2006: MCTF report delivered outlining a plan for

developing the Muon Collider concept based on recent ideas in the realm of ionization cooling, and an associated cooling R&D plan that can be implemented starting in FY2007 (available via AAC Web-page)

f MCTF and NFMCC Co-ordinationMCTF and NFMCC Co-ordinationMar’07: S. Holmes has asked that a NFMCC & MCTF coordinating committee be formed to coordinate the NFMCC & MCTF Muon Collider activities & ensure the overall R&D is coherent & effective

The Muon Collider Coordinating Committee (MCCC) had been formed and had its first meeting March 19th, 2007

Meets ~1/month, in addition to working weekly meetings of NFMCC and MCTF, annual workshops, etc.

CROSS-PARTICIPATION


f NFMCC-MCTF ProtocolNFMCC-MCTF Protocol

1. The NFMCC and its members are invited to participate in the MCTF program.

2. If the mutually agreed upon activities require MCTF resources, the resources,

milestones and deliverables would be defined by an MOU between Fermilab

and the NFMCC.

3. NFMCC institutions receiving support for MCTF activities would do so within

the framework of the NFMCC (i.e., through the process defined in point 2).

4. Institutions participating in the MCTF that are not presently part of the NFMCC

would be encouraged to join the NFMCC if this seems appropriate (decided

by mutual discussion between the MCTF and NFMCC leadership).

It seems natural that the MCTF manages those activities that requireFermilab to play a significant role as a host laboratory, and the NFMCC manage those activities with an international character

We desire and expect NFMCC participation in MCTF managed R&D. To facilitate this, we have formulated a protocol to follow:

f SummarySummary FNAL Steering Group report calls for increase of Muon Collider and Neutrino Factory R&D Since formation of the Accelerator Physics Center, all Muon

Collider and Neutrino Factory R&D programs are being coordinated by the APC’s Muon Accelerator R&D Department

1-yr old MCTF progressed along three lines: Theory and simulations (cooling simulations, collider optics, etc) Hardware development (HCC section design, HTS conductor, etc) Experimental beam research (MTA p-line, MANX preparations).

MCTF efforts in near future will be concentrated on Construction and commissioning of MTA beamline Experimental studies with proton beam in MTA (HPRF, MuCool) Development of HCC magnet and HTS conductor studies Planning, design, construction for 6D MANX experiment

These efforts involve effective collaborations: With NFMCC: MCCC has made a good start Muons Inc; other Labs and Universities
