Zusammenfassung:Electron multiplier tube, comprising along the principal axis an electron-emitting surface, several dynode stages with distributed structure, capable of reflux secondary electron emission, and an electron-receiving surface, as well as means producing an electron-accelerating electric field generally oriented along the principal axis, from the electron-emitting surface to the electron-receiving surface. With it is associated coil means producing a magnetic field generally oriented along the principal axis of the tube. Particular example is a photomultiplier with high spatial resolution.
