FIELD: physics.
SUBSTANCE: analysis based on energy and mass is carried out in superimposed radial electric field of a Hughes-Rozhansky energy analyser and the magnetic field if a Wien filter and the longitudinal electric field of the Wien filter which lies across said two fields. The Hughes-Rozhansky energy analyser and the Wien filter are merged in a single structure, the Wien filter being cylindrical. The ion detector and the distance between cylindrical plates are determined by focusing conditions of the target ions.
EFFECT: broader functionalities of charged particle energy-mass analysers.
