Web1 Introduction. Superconducting radio frequency photoinjectors (SRF guns) have advantages for operating in continuous wave (CW) mode and generating the high-brightness and high-current beams required by CW X-ray free electron laser (XFEL) [1, 2] and energy recovery linac (ERL) facilities [3, 4].Similar to the normal conducting rf guns, SRF guns are … WebA photocathode is a surface engineered to convert light into electrons using the photoelectric effect.Photocathodes are important in accelerator physics where they are utilised in a photoinjector to generate high brightness electron beams. Electron beams generated with photocathodes are commonly used for free electron lasers and for …
WebA photomultiplier tube (PMT) consists of a photocathode followed by an electron multiplier. A single photon ejects an electron from the photocathode. Electric fields in the PMT … WebA demand on modern high brightness photo injectors required for a successful operation of linac-based free electron lasers is the possibility to generate beams with minimized beam emittance. A major way to optimize this parameter is the operation of
