Fig. 1From: Electric ion dispersion as a new type of mass spectrometerA sketch of the line charge device: within the plane, particles enter from the bottom and are excited into oscillations in x with approximately constant y-velocity. The circles indicate positive charges of charge +Z e with a vertical spacing of 2H. In the implementation, likely H would be very small so that particles cannot exit through the sides of the device or, if practical considerations are required, the isolated charges could be replaced by a line of charges with uniform linear charge densityBack to article page
