Title: Transverse Phase Space Measurement Using Tomographic Method

Abstract

Transverse phase space tomography using a set of a quadrupole magnet and a beam profile monitor is useful method to measure phase space distribution of electron beams. However, the energy distribution of measured beam distorts result of the tomographic method, since the assumption of a mono-energetic beam is essential in this method. In order to evaluate the effect of energy distribution, the numerical simulation was carried out. As the result of simulation, we found that the energy spread of the main component does not have significant effects, but the low energetic tail severely distorts the reconstructed phase space distribution. However, the center core was preserved in the distorted image. Therefore an elliptical analysis method was introduced to pick up the center core information as precise as possible. By using this method, we could obtain the Twiss parameters and emittance of center core which are almost consistent with initial distribution.
