Abstract

<p>Determining the elemental composition of planetary surfaces with a high precision is essential to investigate planetary origin and evolution. In the future planetary missions, landing/roving exploration of planetary bodies are required as well as a remote observation from the orbit of spacecraft. In-situ measurement of planetary surface in the landing/roving missions provides us a new insight of geochemical and mineralogical information of planetary materials which are not obtained from the remote sensing observation. We have been developing the compact and light-weight Active X-ray Spectrometer (AXS) consisting of an excellent energy-resolution silicon drift detector and a pyroelectric X-ray generator for future roving missions to perform elemental analysis on the surface materials of planetary bodies. In this paper, the basic research and development of pyroelectric X-ray generator of the excellent performance AXS is presented and discussed.</p>
