1MW - 704 MHz RF test stand at CEA-Saclay

In the frame of the CARE/HIPPI programme, superconducting accelerating cavities for pulsed proton injectors are developed. Qualification of these 704 MHz RF structures fully equipped (housed in a helium tank, with tuning system and power coupler), requires to perform high power tests in the existing horizontal cryostat CryHoLab. Before the CARE programme started, not any of European test sites was equipped with a 704 MHz high power RF source in the MW range. During the last two years, CEA-Saclay built and ordered the necessary RF equipments to make such a platform for high power RF tests in a cryogenic environment available to the partners in HIPPI and later on to any other interested European teams.
