强X射线通过铝箔时的透射异常
Transmission anomalies of aluminium foils irradiated by intense laser-produced X-ray radiation
摘要
由大功率激光所产生的强X射线(简称LPX)线谱,波长处于8～11A,时间脉宽130ps,功率密度达5×10~2W/cm~2或单色功率密度达4×10~4W/cm~2·keV(对应于波长10A),在其穿过铝箔时观察到透过率的非线性异常增大。
Abstract
Anomalous nonlinear increasing in transmissivity of aluminium foils in the wavelength range 8～11 A has been observed. These foils were irradiated with the monochromatic X-ray radiation at about 5×102 W/cm2 generated by a high-power neodymium-glass laser.
