    Abstract: Provided herein is an electro-magnetic field former for controlling charged particle trajectories in a scanning charge particle source including a pair of induction coils and C-shaped ferromagnetic yokes which are positioned in the air space between the particle source and a target at the target edges to normalize the angle of incidence of the particles relatve to the target and to deflect scattered particles into the target edges. Also provided is a field former controller to compensate for induced flux variations caused by an oscillating particle beam.
