چکیده انگلیسی
The mass dispersion of the QQEBEQQ symmetric recoil mass spectrometers can be improved substantially, so potentially their resolution, by inserting cylindrical plates inside the magnet gap, thus creating there a crossed field analyzer. The conditions to keep stigmatic and energy focusing were derived for such a modified system. Applied to some specific cases these formulae predict an increase of even 200% in mass dispersion for an increase of total charged particle path by 7.92%. The mass separation of equal momentum beams at middle of the instrument and the resolution-beam acceptance product were calculated for two representative separator configurations.
