Complete Scheme of Ionization Cooling for a Muon Collider.

摘要

The conclusions of this report are: (1) New 1.5 TeV Collider lattice has more conservative IP parameters--(a) Luminosity 1 x 10(sup 34) achieved with bunch rep rate (approx.)12 Hz but requires depth (approx.)135 (m) to limit neutrino radiation, (b) Collider ring must be deep (eg 135 m of ILC) to control neutrino radiation, and (c) Proton driver ((approx.)4 MW) is challenging; (2) Complete cooling scheme achieves required muon parameters--All components simulated (at some level) with realistic parameters, but much work remains; (3) Possible problem with rf breakdown in specified magnetic fields--Solutions with gas in cavities appear to work, and designs with open cell rf are promising; and (4) Lower cost acceleration possible using pulsed magnets in synchrotrons--Rings fit in Tevatron tunnel, and second ring uses hybrid of fixed and pulsed magnets.
