Particle distribution of the electron beam extracted from a thermionic RF gun in longitudinal phase space is crucial for electron bunch compression. Because space charge effects in the RF gun are not fully understood, an efficient bunch compression scheme employing magnetic chicane or alpha (α-) magnet is not easily designed. In order to measure the distribution in the longitudinal phase space of relatively lower energy electrons (below 2 MeV), we have studied a novel method for direct observation of electron energy employing velocity dependence of opening angle of Cherenkov radiation. Intrinsic energy and temporal resolution are discussed by showing a numerical ray-trace simulation.
