FIELD: physics.
SUBSTANCE: apparatus for detecting micrometeoroids and space debris particles has a substrate consisting of a metal film, a dielectric and a metal plate. The metal film is divided by a zigzag gap into two halves, the first half being connected to the negative terminal of a power supply and a second amplifier, and the second half being connected to the ground electrode of the power supply. The width of the strips of the first half is greater than the width of the strips of the second half. Above the metal film there is a metal gauze which is connected to the positive terminal of the power supply and a first amplifier. Above the metal gauze there is an earthed gauze. Both amplifiers are connected to a unit for processing signals and detecting particle charge.
EFFECT: high information capacity of the device and simple design of the detector.
