Development of X-ray diffraction device onboard exploration rover for lunar and planetary surface material research

行星表面漫游车上的x射线衍射装置是研究月球和行星表面物质的有用仪器。在不久的将来，日本地面勘探计划进行固体行星地质调查。在这种勘探中进行了化学和矿物分析。对于本研究，设备的三个部分是需要开发的元素；x射线产生装置、探测器及样品制备和输送机构。本文主要研究了x射线发生器的设计和高压电气装置的选择。选择CCD传感器作为x射线衍射探测器，尝试检测岩石粉末样品的衍射线和能谱。我们可以证明CCD必须是行星探测漫游者上的强大传感器。本文还研究了小型x射线发生器和电子装置。

X-ray diffraction device onboard planetary surface rover is useful instrument for lunar and planetary surface material research. In near future of Japan surface exploration is planning for solid planets geological survey. In such exploration chemical and mineral analysis are carried out. For this study three parts of the device are elements to be developed ; X-ray generation device, detector and sample preparation and transportation mechanism. In this research we study design of X-ray generator and selection of high-voltage electric device. The CCD sensor is selected for a detector of X-ray diffraction, and tried to detect the diffraction lines and energy spectrum from rocky powder samples. We can demonstrate CCD must be a powerful sensor onboard planetary exploration rover. Compact X-ray generator and electronic device are also investigated in this research.
