Photocathodes - PowerPoint PPT Presentation


Electron Beam Generation and Cathode Research at HERACLES Facility

Research at the HERACLES facility focuses on electron beam generation and cathode development for high-current applications. Photocathodes play a crucial role in providing low energy spread beams required for processes like FEL-lasing. GaAs emerges as a promising candidate for spin-polarized electro

Ion Bombardment Effects on GaAs Photocathodes

Examining the impact of ion bombardment on bulk GaAs photocathodes with different surface-cleavage planes. Ion back-bombardment in photo-gun setups is a significant factor limiting the operating lifetime of photocathodes. Investigation includes H-ions implantation into GaAs, experimental apparatus d
