The dc photocathode electron gun is designed for future light sources based on energy-recovery linac and consists of a Cockcroft\u2013Walton generator, a segmented cylindrical ceramic insulator, guard-ring electrodes, a support-rod electrode, a vacuum chamber, and a pressurized insulating gas tank.
