Towards high brightness electron beams from multifilamentary Nb_{3}Sn wire photocathode

In order to find electron sources of low emittance and high quantum efficiency, single tip cathodes with a microstructured surface are investigated. Emission currents up to 310 A were obtained, by combining a 2 ns, 50 kV accelerating voltage pulse with a 266 nm wavelength, picosecond (σ_{t}=6.2  ps)...
