Abstract : Under the auspices of the U.S. Army grant we have made considerable strides in all aspects of PSII technology. We have developed a fundamental understanding of plasma physics issues such as sheath propagation, secondary electron emission and heat transfer in targets. These studies have a direct relevance to practical issues such as dose uniformity and batch processing feasibility of PSII To monitor the ion species and their interactions in-situ we have designed and developed a electric field analyzer and are currently installing a LIF system. We have developed a RF plasma source for the long IBED runs required to produce thick coatings.
