Semiconductor projectile impact detector

摘要

A semiconductor projectile impact detector for use in determining micrometeorite presence as well as its flux and energy comprises a photovoltaic cell which generates a voltage according to the light and heat emitted by the micrometeorites upon impact with the cell. A counter and peak amplitude measuring device are used to indicate the number of particules which strike the surface of the cell as well as the kinetic energy of each of the particles.
