Outline of Final Research Achievements

We studied production of high energy electrons using plasma wakefield acceleration for calibrating detectors, such as Super Kamiokande.
As a result of computer simulations, we found higher energy acceleration can be expected in plasma with higher density, where wavelength of the plasma is much shorter than bunch size of the electron beam, though energy spectrum of electrons is widely spread. However, the maximum energy of electrons was not high enough to be utilized for detector calibration. As a by-product of our study, we could observe nonlinear Compton scattering of electron and CO2 laser beams.
