Research Abstract |
This work aims at elucidating mechanism of microbunching instability using high brightness electron beam generated from a photoemission dc electron gun. A train of microbunched electron beam spaced by 0.03 mm is provided from the gun to a Smith-Purcell radiation monitor where the microbunching instability is studied. Our development of the gun led to find an optimum configuration for a high voltage photoemission gun for operation at voltage higher than 500 kV. We generated 500 keV-beam with 1.8 mA for the first time. This gun was shipped to KEK for commissioning of the compact energy recovery linac. We decided to use a 250 kV photoemission electron gun at JAEA for the present study instead of the shipped 500 kV gun and started to prepare the Smith-Purcell radiation experiment.
