A two solenoid lens designed has been designed for tranverse focusing of charged particle beams. Solenoids focus the charged particles in the transverse direction, but chromatic effects in the beam weakens the focusing effect from the solenoid. By placing a weaker strength solenoid upstream of the final solenoid, the chromatic effects are mitigated.
