Abstract
An electron capture dissociation apparatus comprises ion guide electrodes, an electron emitter, and an electron control device. The ion guide electrodes are arranged along a central axis and spaced circumferentially to circumscribe an interior space extending along the central axis. The electron emitter is disposed outside the interior space. The electron control device is configured for focusing an electron beam from the electron emitter toward the central axis, along a radial electron beam direction between two of the ion guide electrodes, and for decelerating the electron beam in a DC decelerating field of adjustable voltage potential directed along the electron beam direction.
