摘要: 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。

Abstract: 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 2ω0 laser.

Key words: backlighter targets, ionicity, line emission
