Abstract
An ion detector having a planar electrically conducting entrance plate, a converter assembly including a planar electrically conducting converter plate and a converter member for providing free electrons upon impact of ions, a planar electrically conducting exit plate having an exit window, a magnet assembly, and an electron detection assembly. The planes of the converter plate and the entrance plate are parallel and electrically biasable in order to provide a homogeneous electric field. The magnet assembly provides a homogenous magnetic field between the converter plate and the exit plate, the magnetic field extending parallel to the plane of the converter plate. The ratio between the electric and the magnetic field is such that the electrons emitted from the converter plate travel to the exit window and are detected by the electron detection assembly.
