Title Mechanical design of a 161 MHz, beta=0.16 superconducting Quarter Wave Resonator with steering correction for RIA
Type Poster cavity design / fabrication / treatment
Abstract The RIA driver designed at MSU includes 161 MHz, b=0.16 superconducting Quarter Wave Resonators with steering correction. The rf design of the cavity was previously performed at MSU and used in beam dynamics simulations for RIA. The cavity mechanical design and final rf simulations have been performed at LNL, resulting in a double-wall structure with short length along the beam line, compatible with both separate vacuum between beam line and cryostats or unified one. This design can be easily extended to different frequencies, e.g. to obtain the 80 MHz b=0.085 cavity required in RIA, and it could be used also in the high intensity deuteron injector of the SPES project at LNL. The construction of the first prototype has recently started.  The cavity mechanical design characteristics and their influence on rf behavior will be presented and discussed.
