在磁约束聚变实验装置的物理实验中,为了测量高温等离子体辐射的某特定能量区域的X射线或其他核辐射能谱的时、空分布,需要在托卡马克的极向和环向方向布置多台X射线探测器,每次放电可同时获得数十个能谱,为了不牺牲能谱中的重要信息(如线辐射),以及能量分辨的需要,要求每个能谱有1024道,每个谱采集的时间分为:40、80、160、240ms,可自由设定,每道容量16位,每次放电可同时获得50个能谱,可扩展到80个能谱。
In a physical experiment of a magnetic confinement fusion experiment apparatus, in order to measure the X-ray or other nuclear radiation energy spectrum of a certain energy region irradiated by high-temperature plasma, the spatial distribution needs to be arranged in the polar and toroidal directions of the tokamak Multiple X-ray detectors, each discharge can be obtained dozens of energy spectra at the same time, in order not to sacrifice the important information in the energy spectrum (such as line radiation), and the need for energy resolution requires each spectrum has 1024, each A spectrum acquisition time is divided into: 40,80,160,240ms, can be freely set, each channel capacity 16, each discharge can be obtained at the same time 50 energy spectrum can be expanded to 80 energy spectrum.
