This DURIP grant, with 96k from DOD and 32k of the University of Kansas matching fund, has been utilized to construct a high-vacuum thin film evaporation chamber. Construction of the major part of the chamber was completed before the expiration of the grant. Installation of the second e-gun was completed at the end of 2001. Installation of the RHEED system will be completed by the first quarter of 2003 due to late delivery of the hardware. A picture of the chamber is shown in Fig. 1. Several research projects have been initiated recently after the chamber was tested. This allows the Pt to extend her research on high-temperature superconducting thin films, particularly Hg-HTS thin films, to coated conductors, which has been considered a critical enabling technology for high power microwave sources in future Air Force systems. The goal to leverage the expertise developed in Pts laboratory in epitaxy of Hg-HTS thin films and apply it to coated conductor applications has been met. The details of the research enabled by this chamber are described in the following. Several manuscripts are under development based on the recent results obtained from this chamber.
