Research overview:
We are making research and development of a dust detector to detect plasma which generates when high speed space dusts collide by applying voltage on the metalized part of a thermal blanket covering the surface of a satellite. If this method can detect dusts, it makes it possible to use the surface of a satellite as a broad detection surface and the frequency of detecting space dusts will remarkably improve. In the detection experiments conducted till last fiscal year in which dusts were mocked by a pulse laser the temperature and the density of plasma, which generates when the metal surface was exposed to pulse laser beams, were measured and it was found that plasma can be detected from the metal surface on which bias voltage is applied. This fiscal year we used MLI which is used for a real satellite and detected plasma by applying voltage on the metalized surface, which showed that plasma which generates when high speed space dusts collide can be detected by this method.
