Advanced high brightness photo-injectors require photo-cathodes with fast response time, long lifetime and relatively high quantum efficiency. Metallic cathodes could satisfy these proprieties and in order to control the emitting material and its surface we produced an yttrium thin film, prepared by PLD (Pulsed Laser Deposition).

Abstract
Advanced high brightness photo-injectors require photo-cathodes with fast response time, long lifetime and relatively high quantum efficiency. Metallic cathodes could satisfy these proprieties and in order to control the emitting material and its surface we produced an yttrium thin film, prepared by PLD (Pulsed Laser Deposition).File in questo prodotto:
