A portion of the remnant Tevatron program infrastructure at Fermilab is being reconfigured to be used for the generation and delivery of proton and muon beams for new high-precisio…
Accomplishments of the Heavy Electron Particle Accelerator Program
D. Neuffer, D. Stratakis, M. Palmer +4
The Muon Accelerator Program (MAP) has completed a four-year study on the feasibility of muon colliders and on using stored muon beams for neutrinos. That study was broadly success…
Wedge Absorbers For Muon Cooling With a Test Beam At MICE
David Neuffer, J. Acosta, D. Summers +2
Emittance exchange mediated by wedge absorbers is required for longitudinal ionization cooling and for final transverse emittance minimization for a muon collider. A wedge absorber…
Commissioning and First Results From Channeling Radiation At FAST
