  3. Background and Plan • MANX LOI submitted to FNAL AAC in May, 2006 to demonstrate ionization cooling in experiment at FNAL • Updated LOI submitted in July, 2007, with advances in the technology, also for FNAL experiment • Last year Muons, Inc. joined the MICE collaboration • Proposal is to do MANX as joint FNAL-RAL project, and run in the MICE beam at RAL as an extension of MICE program • 12/10/2008: Sent draft to MICE exec board and review team for initial review and their (hopefully positive) response • 12/10/2008: Circulated draft to FNAL mgmnt, previous, current, and potential new collaborators for feedback and to build collaboration • 1/2009: Update and submit proposal to FNAL AAC for February 2009 meeting for their evaluation and support • Continue proposal refinement and additional reviews/funding approvals • Design/build HCC at FNAL + new components to run MANX as soon as possible after present MICE program is completed Muon Collider Design Workshop at Newport News, VA USA

  4. Benefits to MANX Great savings in cost and effort Beam line, spectrometer elements DAC, recon, and analysis software can be re-used Potential for MICE groups to join MANX Benefits to MICE Prolongs use of MICE facilities Increases return on investment Improvements to MICE components Potential for MANX groups to join MICE Why MANX in MICE? Muon Collider Design Workshop at Newport News, VA USA

  5. MANX Objectives • Measure 6D cooling in a channel long enough for significant reduction of emittance • Study the evolution of the emittance along the channel by making measurements inside the channel as well as before and after • Test the Derbenev-Johnson theory of the HCC • Advance muon cooling technology Muon Collider Design Workshop at Newport News, VA USA

  6. Other Considerations • Muons, Inc. is largely responsible for the current draft. Future drafts will include more contributions from other collaborators. • MANX is a multi-institutional effort. We need to build a larger collaboration • We are requesting FNAL to continue to support the HCC magnet project • We want to work toward the long-term goals of achieving a NF/MC Muon Collider Design Workshop at Newport News, VA USA

  7. System Described in Draft • MANX Baseline HCC is as in LOIs • Helical solenoid magnet • Best understood at this time. Several versions. • Cooling by liquid helium • Eliminates safety concerns with use of hydrogen • Absence of RF –> continuous energy loss • Eliminates cost and complexity • Parallel studies of RF ongoing Muon Collider Design Workshop at Newport News, VA USA

  8. Uses of MANX HCC • Pre-cooler for NF/MC • Final stage of NF/MC cooling, before re-acceleration • Use for intense stopping muon beams, of interest for Mu2e experiment and others • Epicyclic HCC – application to PC/REMEX (see Afanasev presentation, this conference) Muon Collider Design Workshop at Newport News, VA USA

  9. Helical Solenoid As Envisioned: 3.2m long, ~60 coils Ring diameter: 0.5m Graded field 4T->2T Individually powered identical coils Factor of 2 emittance reduction Matching sections needed? Muon Collider Design Workshop at Newport News, VA USA

  10. Matching Sections – Scheme 1 G4beamline representation of 2 period MANX HCC with 1.5 period long matching sections positioned between the MICE spectrometers 6D Emittance evolution Muon Collider Design Workshop at Newport News, VA USA

  11. Scheme 2: “Off-Axis”, No Matching Magnets G4beamline representation of off-axis matching configuration where HCC is placed at a45º angle to the MICE spectrometer so that beam is oriented along reference path at entrance to HCC. Muon Collider Design Workshop at Newport News, VA USA

  12. Scheme 2, Off-Axis (cont’d) • Losses • No losses upon entering HCC • acceptance of the HCC is 50% larger than MICE spectrometer • Significant losses upon exit from HCC into downstream spectrometer. • Design being optimized to reduce these losses. • Also investigating shorter matching sections (~0.5 period) Muon Collider Design Workshop at Newport News, VA USA

  13. Helium vs. Hydrogen as Coolant5m HCC Pre-Cooler Example HCC pre-cooler filled with liquid helium (red) liquid hydrogen (blue) or With (dashed) and without (solid) 1.6 mm thick Al windows on each end. Transverse Emittance reduction factor: Helium: ~1.65X Hydrogen: ~1.86X Longit Emittance reduction factor: Helium: ~2.5X Hydrogen: ~2.6X 6D Emittance reduction factor: Helium: ~7X Hydrogen: ~8.4X Helium good, hydrogen ~20% better Muon Collider Design Workshop at Newport News, VA USA

  14. Comparison of MANX and MICE • MANX beam 350 MeV/c, MICE ~250 MeV/c • MAX energy loss >MICE energy loss in cooler • MANX cooling factor greater (2 vs. 0.15) • MANX (no RF) uses all beam, MICE (with RF) must use particles that are in Synch w/RF(~10%) • MANX needs better longitudinal momentum measurement for 6D emittance Muon Collider Design Workshop at Newport News, VA USA

  15. MICE/ISIS Beam MANX uses same elements New tune for 350 MeV/c Simulations of new beam tune, rates in progress Muon Collider Design Workshop at Newport News, VA USA

  16. Layout of MANX in MICE Hall Move downstream Tracker and Cal farther Downstream (or transversely) Remove MICE cooling apparatus Install longer MANX HCC w/matching Sections (or rotate without) Muon Collider Design Workshop at Newport News, VA USA

  17. MANX w/Matching Off-Axis MANX MICE Phases + MANX MANX in MICE (Conceptual) Muon Collider Design Workshop at Newport News, VA USA

  18. Upgrades for MANX in MICE • We are examining all of the MICE components for upgrades/additions • So far, improved TOF is identified • MCP device (H. Frisch, U. of Chicago) • Additionally, internal tracker planes are needed in HCC • Scint-fiber w/MPPCs (D. Hedin, V. Zutshi, NIU), or • Scint-fiber w/VLPCs a la MICE Muon Collider Design Workshop at Newport News, VA USA

  19. MCP TOF Counters for Better PL Example: p = 300 MeV/c muon, γ=3, β = 0.94 For L=3m, t = 10.6 ns Δp/p = γ2Δt/t Then For Δt = 50 ps resolution: Δp/p = 4.3% For Δt = 5 ps resolution: Δp/p = 0.43% Tom Roberts and Henry Frisch (U. Chicago) submitted an SBIR proposal for G4BL simulation of MCP gain for TOF counters with microchannel plates. Recent progress on low-cost large-area nanopore MCP materials Muon Collider Design Workshop at Newport News, VA USA

  20. Signals out Power in Active area, fibers MPPCs Electronics Support/mounting frame Detectors Coils Cryostat Vessel Power in Signals out Feedthroughs Trackers Inside HCC Scintillating fiber planes Similar to MICE spectrometer. Use MPPCs(SiPMs) and onboard readout electronics Consider 4 trackers (x, u, v(?) per set and possibly 2 more outside. Purpose: Verify trajectories inside HCC - Helps in commissioning - Provides measure of track quality, losses within HCC Bob Abrams and Vishnu Zutshhi (NIU) have an SBIR proposal on this topic. Muon Collider Design Workshop at Newport News, VA USA

  21. Progress on HCC 4-Coil Model • Initial 4-coil model has been designed and constructed. Now being tested. Ran at 13500A at 4.2K, (designed for 9500A). • Field mapping starting. Muon Collider Design Workshop at Newport News, VA USA

  22. When Could MANX Run? • Longest lead time and cost item is HCC magnet. • Construction of HCC magnet may take 3-4 years (Est: M. Lamm @ July, 2008 MANX Collab Mtg) • Design (~1 year) • Engineering (~1 year) • Acquisition (~ 1 year) • Installation and commissioning (~ 1 year) • Assume resources and $$ match technical schedule!! • If design starts in 2009, 4 year schedule leads to 2013, about 1 year after MICE finishes Muon Collider Design Workshop at Newport News, VA USA

  23. M. Lamm’s Estimate of Cost&Effort(Not in Proposal) • Cost (M&S) and effort estimate guided by 4 coil demo + LHH IR quad cryostat experience • Engineering Design $ 100K • Tooling $ 100K • Main Coil (inc. Cryostat) $2000K • Matching Section (inc. Cryostat) $3000K • Feed Box $ 100K • Magnet commissioning $ 500K • Total $5800K Conceptual Design 9 FTE Engineering Design 10 FTE Procurement 1 FTE Installation/Commissioning 8 FTE Muon Collider Design Workshop at Newport News, VA USA

  24. M. LAMM’s Spending Profile Est.(Not in Proposal) Muon Collider Design Workshop at Newport News, VA USA

  25. MANX Funding Issues(Not addressed in draft proposal) • We seek positive recommendation by AAC to support FNAL-RAL MANX project to secure FNAL resources (staff and $$?) • Design and engineering of HCC may be considered as within the proposed “Muon Accelerator National 5-year Plan”. Construction of full HCC is beyond 5-year plan and would need funds and resources from outside the plan to build it on our technical schedule. • As HCC could be used for stopping muon beam, resources could come from that source (?) • Some additional SBIR/STTR funds (if granted) • Other “as yet un-named” players? Muon Collider Design Workshop at Newport News, VA USA

  26. Much Work Remains • Simulations of 350 MeV/c beam: tuning, µ rates, backgrounds • Simulations of full MANX spectrometer including HCC and new detectors • Reconstruction and fitting of tracks in HCC • Sensitivity analysis, field accuracy requirements, statistics needed, running time estimates • Calibration procedure, run conditions • Review all MICE components for use in MANX • Analysis refinements and additions to MICE analysis SW • Help with new detectors, electronics, and other components Muon Collider Design Workshop at Newport News, VA USA

  27. Summary • We have a draft of our (mainly Muons, Inc.) concept of a full muon cooling demonstration experiment at RAL/MICE. • We want to build the collaboration, and we seek input from potential collaborators on the proposal and on the best way forward. • We want to do what is best for the muon collider community, and meet our existing and future commitments Muon Collider Design Workshop at Newport News, VA USA
