| Outline of Final Research Achievements |
We propose a novel method of plasma-based electron acceleration, in which an electron bunch obtained by laser wakefield acceleration is accelerated by beam wakefield acceleration. The key issue for proof of principle of the method is to obtain a high-charge, quasi-monoenergetic electron (QME) bunch with a narrow energy spread using laser wakefield acceleration. For the generation of a QME bunch, the electron acceleration using a gas jet with a density transition was conducted. The density transition was formed by a shock front induced by a blade inserted into a supersonic gas jet. The scale length of the transition region and maximum density ratio were estimated to be 20 μm and 2, respectively. We have produced a QME bunch containing 2 pC electrons with an energy of 65 MeV using the gas jet.
