Abstract
The longitudinal momentum modulation can be studied with time-resolved beam profiles measured at a region where an appropriate value of the dispersion function exists. In this paper, momentum modulation of two different beam lengths and their mechanisms are discussed. The modulation for a four-millisecond beam comes from beam loading effects at the extraction region of an Electron Cyclotron Resonance Ion Source (ECRIS) and the post-acceleration column after the ECRIS. In the case of a four-microsecond beam bunch, it comes from the transitional chopping process of the Einzel Lens Chopper. These results obtained confirmed the usefulness and effectiveness of the time-resolved profile measurement in studying the longitudinal momentum modulation.
