  Gen­eral in­ter­est has been shown over the last years for the de­vel­op­ment of sin­gle room fa­cil­i­ties serv­ing a pop­u­la­tion of about 2 mil­lion peo­ple for pro­ton can­cer ther­apy. Com­pact ma­chines are needed to ac­cel­er­ate pro­ton beams of few nanoam­peres up to 230 MeV. In this frame­work the pro­ject TULIP (Turn­ing LInac for Pro­ton­ther­apy), patented by TERA Foun­da­tion, fore­sees a linac mounted on a ro­tat­ing gantry used as a booster for pro­tons pre­vi­ously ac­cel­er­ated by a cy­clotron. The linac is com­posed of mod­u­lar units pow­ered by in­de­pen­dently con­trolled kly­strons. The RF power trans­mis­sion is made pos­si­ble by high power ro­tat­ing joints de­vel­oped in col­lab­o­ra­tion with CLIC group. The final beam en­ergy can be var­ied in steps of few MeV from pulse to pulse by am­pli­tude and/or phase mod­u­la­tion of the kly­stron sig­nals, mak­ing pos­si­ble the im­ple­men­ta­tion of ac­tive spot scan­ning tech­nique with tumor multi-paint­ing. The pre­sent paper pro­vides the main char­ac­ter­is­tics of TULIP, de­scrib­ing the dif­fer­ent choices for the linac de­sign pa­ra­me­ters to­gether with the struc­tural de­sign of the sup­port­ing gantry and of the final beam line.
