High voltage DC photocathode guns currently offer the most reliable path to electron beams with high current and brightness. The performance of a gun is directly dependent on its vacuum and high voltage capabilities, determined in large part by the ceramic insulators. The insulator must meet XHV standards, bear the load of pressurized SF6 on its exterior, support the massive electrode structures as well as holding off DC voltages up to 750kV. Construction of UHV and high voltage capable insulators require high purity ceramics and metal components proven to minimize thermal stress between the brazed ceramic rings and metal guard rings. The use of replaceable guard rings is a critical way of controlling manufacturing costs while extending the life cycle of the insulator. Successful fabrication requires proven manufacturing methods in flatness, parallelism, and maintaining alignment of many parts during the brazing process. Taking a scalable, modular approach, the insulator design can be applied to a variety of gun voltages and can be used by other projects. The Cornell-Friatec insulator was designed collaboratively and has now been produced in quantity for Cornell and elsewhere.
