Abstract
Low noise static charging with the MAGIC electromagnetic FDTD PIC code is demonstrated to nanoamp levels. Unwanted currents in a small chamber resulting from necessarily rapid simulated precharging are damped by an elegant solution of simply overlaying the simulated experiment geometry with a time-dependent magnetic conductivity.
