Longitudinal phase space characterization of the blow-out regime of rf photoinjector operation

Longitudinal phase space characterization of the blow-out regime of rf photoinjector operation

Using an experimental scheme based on a vertically deflecting rf deflector and a horizontally dispersing dipole, we characterize the longitudinal phase space of the beam in the blow-out regime at the UCLA Pegasus rf photoinjector. Because of the achievement of unprecedented resolution both in time (...
