  1. m Muons, Inc. Muons, Inc. Grants and Proposals Rolland Johnson, Muons, Inc. In the last four years, several new techniques to cool muon beams have been invented and are under development supported by DOE Small Business Innovation Research grants. A short summary of these grants and 5 new proposals related to muon beams follows. In February, Muons, Inc. and the Fermilab TD sponsored the first annual low-emittance muon collider workshop at Fermilab (~65 participants). There is growing excitement about MC feasibility and synergy with the ILC. Papers can be found at http://www.muonsinc.comworkshop link is at http://www.muonsinc.com/mcwfeb06/ also seehttp://www.muonsinc.com/mcwfeb06/presentations/LEMCWorkshop.pdf MUTAC06: Muons, Inc. projects

  3. m Muons, Inc. Muon Beam Cooling Innovations • Many new inventions and reestablishment of the principle that a neutrino factory should be on the direct path to a muon collider • Muon Colliders need small transverse emittance and low muon flux for many reasons (see workshop main page) • A Neutrino Factory using a very cool muon beam which is accelerated in a superconducting proton driver Linac may be very cost-effective • Several new ideas have arisen in the last 4 years which are being developed under SBIR grants and have the potential to form muon beams with transverse emittances of a few mm-mrad • May say more at end of talk about LEMC workshop favored scenario using extreme cooling and the SC Proton Driver Linac at Fermilab MUTAC06: Muons, Inc. projects
