Abstract
Muons have been accelerated by using a radio frequency accelerator for the first time. Negative muonium atoms (Mu), which are bound states of positive muons () and two electrons, are generated from 's through the electron capture process in an aluminum degrader. The generated Mu's are initially electrostatically accelerated and injected into a radio frequency quadrupole linac (RFQ). In the RFQ, the Mu's are accelerated to 89 keV. The accelerated Mu's are identified by momentum measurement and time of flight. This compact muon linac opens the door to various muon accelerator applications including particle physics measurements and the construction of a transmission muon microscope.
