The Design of the Special Magnets for PIMMS/TERA

In the framework of a collaboration agreement with the TERA Foundation, CERN provided the design, drawings and engineering specifications for two kickers, one chopper and three bumper magnets as well as three magnetic and two electrostatic septa, power supplies for the electrostatic septa, kickers and bumpers including control electronics for the PIMMS/TERA proton and carbon ion medical synchrotron. The first application will be in the Italian National Centre for Hadrontherapy, to be constructed in Pavia. The main features of the devices are described along with the strategic design choices, directed by the demand for very high reliability and minimum maintenance.
