Abstract

Time-of-flight mass spectrometer with a position-sensitive detector (20) for determining energy and pulse of photodissociated ions, the detector (20-24) comprising one or a plurality of electron multipliers (21, 22) and an anode array (23) arranged behind the electron multipliers for determining the position of impringement of the ions, and the time-of-flight mass spectrometer including devices (30-33) for determining the time of flight of the ions.
