Semiconductor Photocathode
- Maud Baylac (CNRS-LPSC)
The goal of the Sealab/bERLinPro project is to build a new generation superconducting RF electron accelerator at HZB. Therefore, a photocathode with high QE and long operation lifetime is required for this project. Multi-alkali antimonide photocathodes deposited on Mo substrate is chosen for this application due to its high QE (>1%) at visible wavelengths and good thermal conductivity....
A UK X-FEL will require a high-performance photocathode to generate an electron beam with the necessary qualities. Caesium Telluride is a candidate material for this photocathode application.
The surface characteristics of a photocathode affect many important factors of the photoemission process including the photoemission threshold, the intrinsic emittance and the quantum efficiency....
