皮秒脉冲激光产生的X射线源能谱精密诊断
Spectrum measurements for picosecond laser produced X-ray sources
摘要
Abstract
In this paper, a transmission curved crystal spectrometer is developed . The transmission curved crystal spectrometer employs a quartz crystal with radius of 200 mm covering the measuring range of 8 keV to 60 keV.We have applied the spectrometer to measure X-ray sources driven by picosecond laser both at XG-Ⅲ and the SGII-Updated laser facility. The characteristic Kα and Kβ line emissions from Cu, Mo, Ag, and Zr were measured.Specifically, the L-shell emissions from Au targets irradiated by the picosecond lasers with different pulse duration were compared. The spectra show good signal-to-noise ratio, which indicates the spectrometer is suitable for the diagnostic of picosecond laser produced X-ray sources.关键词
