Application of Laser Plasma X-rays to Time-resolved Debye-Sherrer Diffraction

摘要

We have studied Laser Plasma X-ray(LPX) in order to apply to time-resolved protein crystallography. We consider that our works will contribute for application of X-ray pulse and breed short pulse handling techniques. LPX pulse duration is femto～pico-second. So, we expect that the laser plasma X-ray system has the potential to satisfy the requirement of time-scale to resolve the early period of protein's structural change. We need about more than 10~(12)photns/shot X-ray to get a diffraction image of organics. We have reinforced our LPX system to get a diffraction image. Now, we try laser pre-pulse effect by experiments and calculations. As the first step of our aim, we will obtain the Debey-Sherrer diffraction image of a biological sample.
