FIELD: measuring equipment.
SUBSTANCE: describes spectrometers that include integral capacity detectors. The integral capacity detector integrates the ion current from the collector, converting it into variable voltage. The detector consists of a collector configured to receive ions in a spectrometer, a dielectric and a plate overlapping with the collector and located on the opposite side of the dielectric. The detector also includes an amplifier.
EFFECT: noise reduction.
