  Radiation therapy attracts attention as one of cancer therapies nowadays. Recently, the radiation therapy of cancer is developing to un-uniform irradiation as IMRT, for reduce dose to normal tissue and concentrate dose to cancer tissue. A photo cathode RF gun is able to generate a low emittance electron beam pulse using a laser light pulse. We thought that a photo cathode RF gun can generate intensity modulated electron beam by optical modulation at the incident optics dynamically. Because of a low emittance, the modulated electron beam pulse is able to accelerate keeping shape. Accelerated electron pulses will be converted to X-ray pulses by a metal target bremsstrahlung method or by a laser inverse Compton scattering method. For the high performance intensity modulated radiation therapy (IMRT), dynamic optical modulation of the electron beam pulse were studied using a Photo cathode RF gun LINAC. Modulated and Moving electron beam will be reported.
