Laboratory simulation.
Abstract
A description is presented of hypervelocity accelerators for the simulation of micrometeoroids, taking into account explosive accelerators, rockets, the light-gas gun, plasma drag accelerators, electromagnetic accelerators, electrostatic accelerators, and the basic requirements which a suitable accelerator facility will have to satisfy. High velocity impact processes are examined, giving attention to the initial partition of energy, the melting and even evaporation of both projectile and target materials, the study of cratering, ejecta, the phenomenon of the impact light flash, questions of impact ionization, the impact ionization effect, and the energy balance. Impact ionization detectors are also considered and penetration and impact phenomena are discussed. A description of detectors flown in space missions is presented and the sensitivities of different impact ionization detectors are compared.
