Abstract

A detector assembly has a current measuring device with a saturation threshold level, and a gain variation means. A signal is generated in response to the particles detected, a first data point corresponding to a peak of interest is acquired from the signal. If the first data point is near, at or above the saturation threshold level of the current measuring device, the gain of the gain variation means is adjusted such that the peak of interest in the signal is reduced in intensity.
