The construction of the cryomodule initially planned for the SOLEIL project is underway by a collaboration between CEA Saclay and CERN. The two single cell cavities, equipped with superconducting loop couplers, have been designed to allow an efficient damping of HOMs. The 352 MHz Nb/Cu cavities were fabricated and tested at CERN, and reached Q0=3 109 at Eacc=6 MV/m and T=4.5 K, above specifications. The tuning system under vacuum is an improved version of the one developed for the TTF 9-cell cavities. The assembling of the cryomodule is presently in progress at CERN where RF power tests are planned to be performed before the end of year 1999. |
