Scientific paper

Results are reported for simulation studies of high-velocity microparticle impacts, which were performed using an electrostatic dust accelerator for conductive particles and a linear dust accelerator in which dielectric particles are charged by an ion beam. A laboratory model of a HELIOS instrument and a high-electric-field detector were employed to measure the ion composition of the impact plasmas produced by fast dust particles striking a gold or a tungsten target. Time-of-flight spectra are analyzed for aluminum, polystyrene, kaolin, soda-lime-glass, quartz, aluminum oxide, iron, and carbon projectiles. It is found that the projectile materials can be divided into two groups (metals/hard dielectrics and soft dielectrics) according to their spectra, that the impact spectra vary with particle velocity, and that background plasma ions are produced by dissociation of molecular ions adsorbed on the projectiles or the targets.
