DETECTION APPARATUS FOR DETECTING CHARGED PARTICLES, METHODS FOR DETECTING CHARGED PARTICLES AND MASS SPECTROMETER

摘要

The invention provides a detection apparatus for detecting charged particles comprising: a charged particle detector for receiving and detecting either incoming charged particles or secondary charged particles generated from the incoming charged particles; a photon generator for generating photons in response to receiving at least some of the same incoming charged particles or secondary charged particles generated from the incoming charged particles as are received and detected by the charged particle detector; and a photon detector for detecting photons generated by the photon generator. Also provided area mass spectrometer comprising the detection apparatus, use of the detection apparatus in TOF mass spectrometry and a method of improving the dynamic range of detection for a TOF mass spectrometer.
