Abstract
A load circuit device having a self-biasing active load circuit, and a related high voltage power supply configured to bias an optical element in a charged particle beam processing system, such as a gas cluster ion beam (GCIB) processing system. The high voltage power supply comprises a variable voltage supply having a load terminal at a load potential and a reference terminal at a reference potential, and a self-biasing active load circuit connected between the load terminal and the reference terminal, and configured to sustain a variable voltage drop between the load potential and the reference potential while maintaining a substantially constant current.
