Different facilities for hadrontherapy have been built in the recent past.

AISHa ion source has been designed by keeping in mind the typical requirements of hospital-based facilities, where the minimization of the mean time between failures (MTBF) is a key point together with the maintenance operations which should be fast and easy. The study of some critical parts of the facilities: the plasma chamber, the containment chamber, etc. have been optimized with the COMSOL Multiphysics® software.

In conclusion we have studied in particular the plasma chamber under certain conditions imposed: the room needs to be cooled by water, which flows in a given path to achieve, through an entrance and septa.
