Title: Novel materials synthesis and large area manufacturing of high QE photocathodes

Abstract

RMD has proposed a fundamental shift in photocathode synthesis [2,3], which promises transformational gains in photocathode response and lends itself to cost-effective, large-area, and reliable manufacturing of commercial MCP-based detectors. Our approach is based on thermal evaporation of the pre-synthesized alkali-antimonide compound instead of diffusing individual alkalis into Sb layer, as has been the practice for the past several decades. The goal of the Phase I research was to demonstrate the feasibility of our approach through chemical synthesis of ultrapure alkali antimonides, congruent thermal evaporation of the material to form stoichiometric photocathode, and preliminary characterization of photocathode for its response uniformity. We are pleased to report that all the stated Phase I goals were successfully accomplished.
