  Projects based on ion linacs have multiplied during the last decade to follow the increasing demand of ion beams, either stable or radioactive, for application in nuclear physics or material studies. Thanks to the continuous progress in SRF (Superconducting Radio Frequency) technology, all these linacs are based on low beta superconducting cavities of different type (half-wave, quarter-wave, bulk Nb or Nb/cu) and make this particular field very active in many laboratories worldwide. In this paper, we review the most recent developments in SRF performed in the framework of FRIB, SPIRAL-2, ATLAS, SARAF, IFMIF, TRIUMF and ISOLDE.

Within the framework of the EURISOL, IPN Orsay has proposed a 352MHz triple-spoke superconducting cavity: for the low energy section (beta = 0.3) of high power proton linear accelerators. In terms of structure design, a triple-spoke superconducting cavity has a complicated geometry, 3D modelling is necessary. More, the design requires simulations which couple electromagnetism with mechanics. To perform these tasks, the mechanics simulation code CAST3M (Calcul et Analyse de Structure et Thermique par la méthode des Eléments Finis) has been linked to the electromagnetism code Opera3D via a dedicated platform, which has been developed for this purpose. This work allows the instantaneous passage from CAD (CATIA) design to mechanical calculations using Cast3m and electromagnetic simulations with Opera3D. As a consequence, the delay of design studies has been considerably reduced. The mathematical advances of the simulation platform are summarized. The electromagnetic and mechanical behaviours of the triple-spoke are presented and discussed in this paper.
