Workshop on research and development of JIEDI (JAXA Ion Engine Development Initiatives) tool for numerical evaluation of ion engine grid lifetime
抄録(英)
Life time assessment of an ion engine needs sputtering characteristics on grid material. Sputter yield on molybdenum due to xenon ion impingement was measured by a conventional weight loss technique using a miniature ion engine. New multiple Quartz crystal Microbalance (QCM) system, positioned in hemispherical on the target plane, revealed the differential sputtering yields. The resulted sputtering yields agreed with the data given by the other conventional methods.
