The U.S. Department of Energy awarded CCR two new programs to advance RF source technology. CCR will work with SLAC National Accelerator Laboratory to develop high efficiency klystrons for the next generation of accelerators. The goal is to provide klystrons operating at efficiencies exceeding 85%, which is considerably higher than current technology. In the second program, the company will team with N.C. State University to explore additive manufacturing of klystrons. If successful, this will dramatically reduce the price of RF sources for accelerators, particularly for big science programs where hundreds or thousands of a single klystron type will be required. The program will address issues with additive manufacturing of copper, ensuring material quality, and providing the required finish for high field surfaces. The test device will be a klystron used in commercial cancer therapy accelerators.
