Development and Fabrication of New Multilayr X-ray Detectors for the Purpose of Temporal and Spatial X-ray-Energy Observations on the Basis of Our New Theory on the X-ray Response of Semiconductor Detectors

我们新提出的半导体探测器x射线能量响应理论应用于新型多层半导体x射线探测器的制作；该理论的特点是x射线产生的电荷对输出信号的三维扩散效应。此外，这一发现显著地修正了从教科书中的传统理论和最近麻省理工学院的理论推导出的等离子体电子温度的评估值。扩展了我们的理论，以便分析多通道半导体阵列数据。这些结果成功地应用于制造上述升级的高能量敏感和时间能量分辨x射线探测器。这些探测器现在安装在GAMMA 10串联镜面等离子体限制装置中；重要的高能量敏感特性提供了有用的数据，包括以层析重建空间分布形式的相对论性高电子温度观测。这些新型多层探测器利用每层探测器的输出信号比显示出可靠的单次等离子体温度观测结果。仅使用一次等离子体射击所分析的温度，就可以通过使用60次常规使用的NaI (T1) x射线探测器一致地确认。这表明了新开发的多层探测器对难以观察的再现性差的现象的有用性，包括elm，内部中断和其他稳定性指示信号。

Our newly proposed theory on the x-ray-energy response of semiconductor detectors is applied for the fabrication of new multi-layr semiconductor x-ray detectors ; this theory is characterized by a three-dimensional diffusion effect of x-ray-produced charges on output signals.Also, this finding significantly modifies the evaluated values of plasma-electron temperatures Te deduced from the conventional theory in textbooks and the recent MIT theory. Our theory is extended so as to analyze multichannel semiconductor array data.These results are successfully applied to fabricate the above-described upgraded high-energy-sensitive and temporally energy-resolved x-ray detectors. These detectors are now installed in GAMMA 10 tandem mirror plasma confining device ; the significant high-energy-sensitive properties provide useful data including relativistic high-electron-temperature observations in the form of tomographically reconstructed spatial distributions.These new multi-layr detectors show reliable one-shot plasma temperature observations using the output signal ratio from each detector layr. The analyzed temperatures using only one plasma shot are consistently confirmed by a conventionally utilized NaI (T1) x-ray detector using 60 shots.This indicates the usefulness of the newly developed multilayr detector for difficult observations of poorly reproducible phenomena including ELMs, internal disruptions, and the other stability-indication signals.
