LIGHT is an innovative high-frequency linac based proton therapy system designed to accelerate protons up to 230 MeV: it consists of three different linac sections i.e. a 750 MHz Radio Frequency Quadrupole (RFQ) accelerating the beam up to 5 MeV; a 3 GHz Side Coupled Drift Tube Linac (SCDTL) up to 37.5 MeV; and a 3 GHz Coupled Cavity Linac (CCL) section up to 230 MeV. The compact and modular design is based on cutting edge technologies developed for particle colliders and adapted to the needs of hadron therapy beams. The LIGHT development machine is currently being built at CERN and this paper describes its design aspects and its different stages of installation and commissioning.
