The element was fabricated with a piezoelectric PZT plate. Its surface contained a set of electrodes; a collector and four narrow electrodes. The narrow electrodes served to measure the coordinates during collision. If the coordinates lay within a sensitive region of the element, this event was tagged as "true". When tagged "true", the signal form from the collector was recorded to be analyzed later on. The proposed idea was discussed by bombarding the PZT element with hypervelocity carbon particles. The stand-alone PZT element was successful to categorize each event "true or false" and to record the output signal form from the collector., 形態: カラー図版あり, 資料番号: AA0064297107}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)}, title = {超高速微粒子検出器開発: 事象真偽判定}, volume = {25}, year = {2009} }
