The Spiral 2 facility is in construction phase. The driver is a super-conducting linac composed of two types of QWR cavities, beta = 0.07 and 0.12 operated at 88.05 MHz. Each cavity is fed by a radiofrequency antenna coupler designed to accept up to 40kW CW. The tests of the prototype couplers have been successfully achieved in the two types of cavities. The manufacturing is finished and the processing of the 26 couplers is under way. We report the technological choices and the major issues of the process, including the absence of TiN plating. We present the main results of the tests and the processing of the couplers.
