The development of very high duty cycle, high gradient photoinjectors is critical for the next generation of accelerator systems, such as X-ray free-electron lasers (FELs), inverse Compton scattering (ICS) sources, energy recovery linacs (ERLs), injectors for linear colliders, as well as a variety of industrial systems for homeland security applications. NCRF photoinjectors have a proven track record at generating the high-quality beams necessary for these applications, however they are limited in large part to relatively low duty cycles due to ohmic wall looses. Thus a key issue for high average power, normal conducting, photoinjectors is effective structure cooling [9]. The fabrication of current high average-power photoinjectors relies on conventional design and fabrication techniques with many limitations. Advances in Solid Freeform Fabrication (SFF) technology may make it possible to design and produce near net-shape copper structures for the next generation of very high rep rate, high gradient radio frequency (RF) photoinjectors. RF and thermal-management optimized geometries could be fully realized without the usual constraints and compromises of conventional machining techniques*. Further advances in SFF and powder metallurgy (P/M) techniques, with the ability to fine tune material properties, may soon make it possible to produce monolithic, thermally robust RF structures faster and cheaper than ever before.
