High gradient silicon carbide immersion lens ultrafast electron sources

High gradient silicon carbide immersion lens ultrafast electron sources

We present two compact ultrafast electron injector designs with integrated focusing that provide high peak brightness of up to 1.9 × 1012 A/m2 Sr2 with 10's of electrons per laser pulse using silicon carbide electrodes and silicon nanotip emitters. We demonstrate a few centimeter scale 96 keV i...
