This paper summarizes a fast numerical technique for solving Poisson's equation in an axisymmetric Malmberg-Penning trap. The method assumes the charge density qn(r,z) and boundary potentials {phi}(r=R{sub w},z) are specified, and solves for the electrostatic potential {phi}(r,z) within the cylinder. The solution of Poisson's equation is often an important step in the numerical reconstruction of the nonneutral plasma density profile n(r,z) from the axially integrated measurements of the charge density profile, Q(r)=qA{sub h}{integral}dzn(r,z), where q is the charge and A{sub h} is the effective area of the collimator hole.
