Rayleigh-Taylor不稳定性背光照相实验背光源初步理论研究

THEORETICAL STUDIES OF BACKLIGHTER FOR INDIRECTDRIVE RAYLEIGHTAYLOR EXPERIMENTS

为开展中等功率激光器上ＲａｙｌｅｉｇｈＴａｙｌｏｒ不稳定性背光照相实验，对多种背光源靶材料及其发射的Ｋ、Ｌ、Ｍ带Ｘ光谱强度作了数值模拟计算。计算结果表明，用数百焦耳倍频激光来产生能量为２ｋｅＶ左右的Ｘ光背光源是可能的。

For RayleighTaylor instability experiments diagnosed by backlight Xray image on a moderate power laser facility, several kinds of backlighter materials and thier Xray spectra have been studied theoretically. The simulated results show that it is possible to produce about 2 kev Xray backlight using a several hundred Jaules 2ω0 laser.
