Siemens has earned three con­tracts to de­liv­er ION­TRIS Par­ti­cle Ther­a­py ac­cel­er­a­tor sys­tems* to be op­er­at­ed in Mar­burg and Kiel, both in Ger­many, and in Shang­hai, China. The ac­cel­er­a­tor part con­sists of an in­jec­tor (7 MeV/u pro­tons and light ions) and a com­pact syn­chrotron able to ac­cel­er­ate pro­ton beams up to 250 MeV and car­bon ions up to 430 MeV/u. These beams can be slow­ly ex­tract­ed and de­liv­ered to a choice of fixed-an­gle hor­i­zon­tal, se­mi-ver­ti­cal and ver­ti­cal beam-ports. An overview of the de­sign will be given and the sta­tus of the in­stal­la­tion and com­mis­sion­ing work for the first two pro­jects will be shown.
