 note = {We report on an experimental study of optical transition radiation (OTR) from high energy electron bunches generated by laser wakefield acceleration (LWFA) using the J-KAREN-P laser at Kansai Photon Science Institute (KPSI), QST. A three-color OTR imaging system was built to monitor the electron bunch duration variation in a single shot. By the insertion of a blade, relatively stable electron beams were generated using the density transition injection regime. Obvious OTR signal difference was observed between the conditions of pure gas and mixture gas. This experiment suggest that the combination of a sharp density down-ramp and pure gas is beneficial for generating stable and high-brightness electron bunches and the realization of a compact x-ray free electron laser., 日本物理学会第77回年次大会},
