Intrinsic emittance reduction of copper cathodes by laser wavelength tuning in an rf photoinjector
With the improvement of acceleration techniques, the intrinsic emittance of the cathode has a strong impact on the final brightness of a free electron laser. The systematic studies presented in this paper demonstrate for the first time in a radiofrequency photocathode gun a reduction of the intrinsi...
