Outline of Final Research Achievements

We have succeeded to generate 28 keV laser Compton x-rays using 35 MeV electron beam and 800 nm Ti:Sa laser. An artificial blood vessel, which contained a thin stent and coil was placed 4 meters away from the x-ray source point. X-ray radiograph of the stent and coil was successfully measured with an imaging plate. We also confirmed that the 60 keV laser Compton x-rays was generated via the Compton scattering of the laser-plasma-accelerated electron beam and Ti:Sa laser pulse. Real-time radiography of the thin stent during surgery using the laser Compton x-ray will be possible if we boost the x-ray energy to 80 keV.
