  1. Ring Coolers/Emittance Exchange Structure and Manpower Rajendran Raja Fermilab • Sub-group activities:- • Ring Coolers • Palmer Ring • UCLA Ring • Balbekov Ring • Ring Coolers – global issues • Injection/Extraction • Kicker design • Rings vs Snakes vs spirals • Quadrupole Linear channel • Muon Collider Conceptual design • Have a design on paper to go from collection to collision • Lithium lens ring coolers? • Neutrino factory-Optimize Study II to include emittance exchange. • Collection of muons:- • Neuffer buncher Rajendran Raja, IIT Feb 2002

  2. Ring Coolers- Palmer ring • Workers- Palmer(10%), Fernow(10%) • Worklist- Take initial LBL workshop design and simulate in ICOOL with realistic fields. Evaluate performance. Needs help. Rajendran Raja, IIT Feb 2002

  3. Ring Coolers- UCLA ring • Workers- Garren(50%), Kirk(20%), Fukui(60%),He(?) • Worklist- • Optimize cooling Energy, Minimize losses • Optimize ring design • Design Injection/Extraction Rajendran Raja, IIT Feb 2002

  4. Ring Coolers-Balbekov Ring • Workers- Balbekov(50%),Usubov(100%), Kahn(30%), Raja(30%) • Worklist- Show Geant Model gives same result as Balbekov simulation • Show results invariant with realistic fields • Solve Injection Extraction. Rajendran Raja, IIT Feb 2002

  5. Ring Coolers- Global Issues Injection/Extraction (no one) Kicker design (Palmer(10%), Summers(10%) Rings vs Snakes vs spirals(no one) Rajendran Raja, IIT Feb 2002

  6. Quadrupole Linear Channel • Workers- Johnstone(40%), Makino(70%), Berz(20%), Errede(20%) • Worklist- Design Quadrupole cooling channel- Show it cools and that it may be useful for early cooling stage. Rajendran Raja, IIT Feb 2002

  7. Muon Collider Conceptual design • We would like to show conceptually that the muon collider may be feasible by simulating collection and cooling using ring cooler ideas. • Workers- No one • Simulate Collection, Cooling, Rings. • Get to grips with Lithium lens final stage Rajendran Raja, IIT Feb 2002

  8. Optimize Neutrino factory Design by adding emittance exchange • It would be good to work this problem through seriously by adding emittance exchange (either via snakes/spirals or if injection is solvable using rings) to see how much gain results in neutrino factory design/ costs. • Workers- No one Rajendran Raja, IIT Feb 2002

  9. Collection of muons • Dave Neuffer has worked through a new scheme to collect muons (phase rotate and bunch) that avoids induction linacs. • Does this scheme save money? • Can it be used for neutrino factories? • Workers- Neuffer(50%), Elvira (40%) Rajendran Raja, IIT Feb 2002
