摘要
高功率激光束轰击靶材所形成的等离子体可在毫微秒到微微秒时间内产生上百焦耳的脉冲X射线,是一个强度极高的脉冲X光点源(Laser plasma X-ray,简称LPX),它在科学研究、工业和医学上都有重要的应用。
X-ray spectral lines of high-order ionized Si in laser-produced plasma in the target made.of small glass shells have been photographed by KAP-PET crystal spectrography.A set of accompanying He-like fine line structures was observed with high-resolution flat-crystal PET.The temperature and density of the electrons in the plasma were determined,using the experimental data of the intensity of spectral lines and on the basis of the Corona Model.
