A novel method which measures beam axial and rotational velocity for any large-orbit beam with a common guiding center is described. Time-integrated beam velocity information is obtained using a beam block and phosphor scintillator. Results using this method are compared to capacitive probe measurements and trajectory modeling for the electron beam for a cyclotron autoresonance maser oscillator.
