Abstract

Thermal emittance measurements of a CsK₂ Sb photocathode at several laser wavelengths are presented. The emittance is obtained with a solenoid scan technique using a high voltage dc photoemission gun. The thermal emittance is 0.56±0.03 mm mrad/mm (rms) at 532 nm wavelength. The results are compared with a simple photoemission model and found to be in a good agreement.
