The CsSb photocathode fabricated in our preparation system showed quantum efficiency of 5.8 %. We have generated 4 mA beam from the CsSb photocathode at 150 kV. The status of development will be presented., The 59th ICFA Advanced Beam Dynamics Workshop on Energy Linacs}, title = {Development of a multialkali photocathode dc gun for high current operation}, year = {2017} }
