Abstract
Abstract The present invention relates to a circuit for processing a signal received by an electron multiplier. The circuit comprises an electron multiplier followed by an electron collector, a power supply for the electron multiplier, a gain-compressing amplifier for processing the signal delivered by the electron collector, and a feedback path for continuously modulating the gain of the electron multiplier by means of a control circuit which acts on the HT power supply of the electron multiplier. This circuit is particularly suitable for use in mass spectrometry and in helium leak detection.
