Microparticle acceleration for hypervelocity experiments by a 3.75MV van de graaff accelerator and a 100KV electrostatic accelerator in japan

摘要

In-situ dust detectors have been calibrated by dust electrostatic accelerators that can accelerate projectiles to expected mass and velocity ranges of space debris and micro- meteoroids. Unfortunately, In Japan, there was no such a facility dedicated to space science research until our research group was established a few years ago. Therefore, we have developed two high voltage accelerators. One is a modified 3.75MV Van de Graaff accelerator operated by High Fluence Irradiation Facility, Research Center for Nuclear Science and technology, the University of Tokyo (HIT), and the other is a 100kV accelerator dedicated to dust experiment At the Institute of Space and Astronautical Science (ISAS).
