Abstract
A mass recombinator comprises a source of negative ions to be analyzed. These negative ions are accelerated to roughly the same moderate kinetic energy and electrostatically focused to a substantially parallel beam which enters the magnetic field of a dipole magnet at an angle of incidence. The field of the dipole magnet is designed to deflect a substantially parallel beam of negative ions having the same energy and entering at a specified angle of incidence in such a manner that it describes a loop of approximately 264.6 degrees, forming a mass spectrum at a position inside the magnet after deflection of approximately 132.3 degrees. The beam exits the field as a parallel beam substantially where it entered, independent of the mass of the ions. Means are provided at the position of the mass spectrum to block ions of certain mass numbers and to allow others to pass, the passed ions being reassembled and exiting the magnet as a parallel beam substantially where it entered, independent of the mass numbers of the ions.
