Injection and induction acceleration of Ar3+ in the KEK Digital Accelerator

摘要

Four microseconds long Ar3+ beam with injection energy of 15keV/u has been injected into the Digital Accelerator of the High-Energy Accelerator Research Organization. Beam production, transportation, and injection are described as well as machine properties. Results of a free running experiment under static magnetic field and longitudinal confinement and acceleration under a fast ramping magnetic field are presented in detail with a brief discussion on the beam lifetime.
