Abstract :
Advanced high brilliance electron injectors require photocathodes having low thermal emittance, high quantum efficiency (QE) and prompt response. They should be easy to handle and capable of working in the very high electric fields of a RF gun. Magnesium films deposited by laser ablation and sputtering techniques are discussed and QE measurements are presented.
