Advanced Code for Photocathode Design

There are currently no comprehensive computational design tools for developing photocathodes and the electron sources they support. Existing codes do not address the latest photocathode materials, nor do they provide the complete physics related to electron emission. This is complicating design of RF guns and photoinjectors for accelerators and light sources. Statement of how this problem or situation is being addressed Calabazas Creek Research, Inc. proposes to develop an intuitive, user-friendly design tool for analyzing photocathode performance in photoinjectors. The new code will provide access to the required characteristics of the most common materials and include improved physical models to predict performance. The code will be designed for standard personal computers and include an intuitive, user-friendly, graphical interface with extensive post processing features. Commercial Applications and Other Benefits The code will be useful for photoinjector designers for a broad range of accelerator and light source applications. Potential users include national laboratories, academic and industrial research organizations, and designers and builders of photoinjectors, accelerators, and light sources.
