Abstract:
A lens for electron capture dissociation may include: a first electrode and a second electrode spaced apart from each other and arranged along a first direction; and a third electrode and a fourth electrode spaced apart from each other and arranged along a second direction perpendicular to the first direction. The first electrode and the second electrode may be disposed in a space in which a magnetic field is formed in the first direction and trap electrons. The third electrode and the fourth electrode may be in the form of a flat plate and may apply an electric field to the trapped electrons in the second direction.
