  3. Critical Issues •  collider ring design satisfying ALL requirements: •  1cm • circumference  3km (luminosity ~ 1/R) • momentum acceptance  0.6 % • normalized transverse acceptance  200 mmmrad (with errors and beam-beam) • low momentum compaction 10-4 • protection of the vertex detector and tracker from seondaries • robustness: tolerances with technological possibilities (10-5?) •  high gradient vacuum RF in strong magnetic field •  proof that HPRF will work under ionizing beam •  incorporation of RF into HCC • - mini-workshop in spring? •  technologicalfeasibility of 50T solenoid •  complete design of 50T solenoid channel with matching and RF MCTF Scenario - Y.

  4. FY08 MCTF Design & Simulations Plan Collider ring:  Optimization of the collider ring design  Study of implications of the “dipole first” option for detector protection  Beam-beam simulations  Detailing of the design with corrector circuits, injection and collimation systems Basic 6D ionization cooling:  “Guggenheim” RFOFO channel:  More realistic modeling of the magnetic field  Alternative design with open cell RF cavities with solenoids in the irises  Helical cooling channel  Design of RF structure which can fit inside the “slinky” helical solenoid  Design and simulation of the segmented channel  FOFO snake:  tracking simulations and optimization  Side-by-side comparison of the three structures with the aim of choosing the baseline scheme Final cooling:  Complete design of the 50T solenoid channel with required matching between the solenoids  Channel design incorporating Fernow’s lattice with zero magnetic field in RF  Feasibility study of the PIC/REMEX scheme MCTF Scenario - Y.

  5. FY08 MCTF Design & Simulations Plan (continued) Driver:  Schemes based on the Project X linac  high reprate at 8GeV  with acceleration in MI to 30-60GeV  High-gradient induction linac Muon acceleration  RLA  Fast ramping synchrotron  FFAG for the initial stage Bunch coalescing  More realistic modeling of the bunch merging process at initial stages of 6D cooling  Alternative scheme with bunch coalescing at high energy (~30GeV).
