DETECTOR OF MICRO METEOROIDAL AND TECHNOGENIC PARTICLES Russian patent published in 2009 - IPC G01T1/34 

FIELD: physics, measuring.

SUBSTANCE: invention concerns field of space instrument making and can be used for examination of a degree and character of pollution of a space technogenic and micro meteoroidal particles. Detector of the micro meteoroidal and technogenic particles contains a target in the form of the sheet condenser superimposed on a metal plate, the receiver of ions, a radiant of a constant voltage. The receiver of ions is mounted on the fixed distance from a target, is symmetrical its axial. Lateral surfaces of the detector consist of two nets located parallelly each other symmetrically located concerning an axis of the detector under a corner to a target. The exterior nets are earthed, and the interior nets have positive potential. In immediate proximity from the receiver of ions is mounted the net which has the negative potential, and interior nets, outputs of the receiver of ions and a target are joined to corresponding amplifiers. Besides the distance between nets in each section is at least equal 1 cm and nets are located under a corner to a target, equal 60°.

EFFECT: expansion of a gamut of recording of particles on mass, measuring of their charge and estimate of motion direction.
