1 Rol - Jan 28, 2011 MEIC Workshop 1 A Business Inspired by Muon Colliders (Can it contribute to electron-ion colliders?) Rolland P. Johnson Muons, Inc. (http://www.muonsinc.com/)http://www.muonsinc.com/ Muons, Inc. has been involved in inventions and their development that have improved the prospects for neutrino factories, stopping muon beams, and high luminosity muon colliders for Higgs factories and at the energy frontier. Support has come from the DOE SBIR-STTR program and from contracts from national laboratories. With over $5M new grants and contracts in 2010, the staff (now 22), the number of research partners at labs and universities, and fields of interest are growing.
