Measurement of hot electrons energy spectrum and fluence by magnetic spectrometer
【摘要】 为了测量超热电子能谱和注量,利用磁感应强度为1200 Gs和600 Gs,对应的量程分别为258 keV～3 MeV、70 keV～1200 keV的电子磁谱仪,测量靶前法线方向和靶后激光传输方向超热电子能谱.用LiF热释光探测器(TLD)记录超热电子的总剂量,然后根据得到的TLD剂量就可推出电子注量,从而得到超热电子的能谱.
【Abstract】 The article presents a method to Measurement of hot electrons energy spectrum using magnetic spectrometer and LiF thermoluminescence dosimeter (TLD).The method is to use magnetic spectrometer of magnetic induction of 1200 Gs and 600 Gs,corresponding quantifier 258 keV～3 MeV、70 keV～120 0keV,measurement of hot electrons energy spectrum in front normal direction and rear laser propagation direction of target,employ LiF TLD to record the total dose of hot electrons,then can deconvolve the electrons fluence according to dose of LiF TLD,and deconvolve the electrons energy spectrum. Because LiF TLDs is calibrated absolutely,the spectrum given by the method represents the relation of the absolute dose and energy.
