Muon Ring Cooler Workshop
March 11-12, 2004

University of Mississippi-Oxford
Dept. of Physics and Astronomy
Lewis Hall Room 228



The goal of the 2 day workshop, at the University of Mississippi-Oxford, is to progress towards a test cooling ring for muons that could be built.
We here in Mississippi will be putting together an EPSCoR proposal to try to get part of the funding.

  1. Weak Focusing 250 MeV/c ring with four/six dipoles.
  2. Two/Four 201.25 MHz RF Cavities, Bore = +-20cm, Thickness = 43 cm, Diameter = 120cm.
  3. 1.8 Tesla DC dipoles with copper coils and iron return yokes
    Vanadium permendur pole faces could buy another 0.3 Tesla if needed.
    Iron = 2.0 Tesla max. Vanadium permendur = 2.3 Tesla max.
                 30 cm magnet gaps.
                 6m beam circumference (not final).
  4. 10 atmosphere hydrogen at 77K.
  5. Magnets are tilted around the beam axis to provide skew quad field components.
  6. One of the open slots is devoted to injection and possible extraction. Provide a low B-field path through the iron to get muons almost onto orbit and then use muon energy adjustment, DE/dx, and RF phase to get the muons on orbit. Needs simulation!!!
  7. One or two of the open slots are devoted to beam diagnostics. X, Y, and stereo planes of 1.5mm scintillating fibers attached to multi anode PMTs at room temperature. Readout my multi-hit TDCs. Orbit one muon at a time. Muon angular spread = +-3 degrees.
  8. Muon Beam Sources:
         FNAL: Muon Test Area, 400 MeV protons.
         BNL: AGS D2 Beam Line.
         JLAB: Drell-Yan photoproduced muons.
  9. Cost estimate for the ring system is ~$5M.
