Development of a Grazing Incidence Spectrometer for Laser Plasma X-ray Sources

Abstract

We develop grazing incidence X-ray spectrometer which is useful for investigating high-energy high-density state produced by highpower laser pulse. Generate several picosecond scale broadband x-ray pulse with 200-1000eV energy by inducing relativistic laser pulse on High-Z foils. With optimized X-ray spectrometer and ultrafast X-ray streak camera. Characteristics of x-ray could be known. These detectors were calibrated with line spectrum from polyimide and third harmonic beam of Ti-sapphire laser. By combination of two devices, both several eV- and sub-picosecond resolution can be achieved. Although short duration of high-energy and high-density state, this x-ray source and detectors permits understanding properties of this state.
