Abstract
A post-acceleration detector for a mass spectrometer comprises a conversion electrode bombarded by an ion beam thereby emitting charged particles having a polarity opposite to that of the ion beam, a charged particle detector amplifying and detecting the charged particles, and a mechanism for moving the conversion electrode relative to the charged particle detector according to the energy of the ion beam.
