Short Solenoid 21, 28, 35, and 42 T Cooling Channel for a Muon Collider | |

| Many scientists are presently discussing the need to build a high luminosity muon collider. A drastic 6D emittance reduction is required. A 45T solenoid prototype with a 14 T superconducting insert and a 31 T copper outset operating in Florida makes the required magnetic fields feasible. A final muon cooling scheme using short 21, 28, 35, and 42 T solenoids is explored by ICOOL simulations. The scheme takes four 57 meters long cooling stages with short HTS solenoids up to 42 T for a 200 MeV/c muon beam. This stage reduces the emittance to (90, 90,850) microns from the (280, 280,1570) microns obtained on previous cooling channels. A septa system makes the muon bunch transversely sliced into 16 parts. Trombones space the 16 bunches into a 3.7 meter long train. One 14 nanosecond kicker aligns all 16 bunches. Finally, a dogbone accelerates the bunch train for injection into a 21 GeV/c ring. RF and snap bunch Coalescence remove empty spaces in the train in 55 microseconds (muon survival is 87%). The final xyz muon emittance is (25, 25, 17000) microns. | ||
