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

星载X射线衍射仪是月球和行星表面物质研究的重要仪器。在不久的将来，日本的地表勘探计划是固体行星地质调查。在这种勘探中，进行化学和矿物分析。对于这项研究，该设备的三个部分是要开发的元素; X射线发生装置，探测器和样品制备和运输机制。本课题研究了X射线发生器的设计和高压电器的选择。本文选用CCD作为X射线衍射仪的探测器，并尝试对岩石粉末样品的衍射谱线和能谱进行了探测。我们可以证明CCD必须是一个强大的传感器机载行星探测车。本研究还对小型化X射线发生器和电子器件进行了研究。

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.
