For PSI's SwissFEL project the laboratory has built an infrastructure which contributes to the production of the C-band (5.7 GHz) accelerating structures needed for the project. This production facility allows the metrology, stacking, brazing, and testing of high precision machined copper discs provided by industry. The photo, above-left, shows the vertical brazing furnace. Above right, one sees four 2 m long structures under high power test. The infra-structure is currently solicited by major European laboratories for the production of S-band (3GHz) and X-band (12 GHz) structures.
