Description

The talk will summarize the state of the art of photocathode based on III-V semiconductor for spin polarized electron beam production and illustrate the limitations that have prevented this class of materials to provide a long term reliability at the highest average beam currents necessary for some of the new accelerator facilities or proposed upgrades of existing ones.
This points to the need of studying and exploring alternative classes of materials that have shown properties that can be leveraged to produce photocathodes that can potentially outperform III-V semiconductors for the production of spin polarized electron beams and support the operating conditions of advanced electron sources for new facilities.
