The worldwide status of superconducting RF cavities and cryomodules for low velocity ion and proton particles is reviewed, with emphasis on the construction and tests of prototypes. A number of different multicell structures at a range of operating frequencies have been successfully realized. This review will cover the progress of several facilities under construction or being proposed: Spiral2, IFMIF-EVEDA, SPL, ESS, FRIB and ADS drivers.

In high intensity proton accelerators neutrons, as well as gamma rays, are generated. At the J-PARC synchrotron the cumulative energy dose will be of the order of several-mSv/h over 1 month user operation. In order to minimize the radiation exposure during maintenance, it is necessary to construct a vacuum system with reliable components which have a long life in such a high level of radiation. In addition, in all machines it is necessary to keep the operating pressure of the beam in ultra high vacuum (UHV) to suppress pressure instability. At J-PARC RCS the UHV conditions were realized without baking and the beam operation has been successful to date. General considerations for vacuum systems for high intensity linear and circular accelerators will be provided in the talk.
