CeB_{6} electron gun for low-emittance injector
Physical Review Special Topics. Accelerators and Beams, 2007 A high-voltage pulsed electron gun has been developed for the low-emittance injector system of the x-ray free electron laser (FEL) project at SPring-8. A single-crystal CeB_{6} cathode was chosen as a thermionic emitter because of its excellent emission ...
