  The company A.D.A.M. (Application of Detectors and Accelerators to Medicine), a CERN spin-off, is working on the construction and testing of its first linear accelerator for medical application: LIGHT (Linac for Image-Guided Hadron Therapy). LIGHT is an innovative high frequency proton linac designed to accelerate proton beams up to 230 MeV for protontherapy applications. The LIGHT accelerator consists of three different linac sections: 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 Cell Coupled 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. A prototype of LIGHT is presently under commissioning at CERN. This paper describes the design aspects and the different stages of installation and commissioning of the LIGHT prototype with emphasis on beam tests results obtained during the past year at different energies.

  The LIGHT accelerator is the first compact Linac that will deliver proton beams up to 230 MeV for cancer treatment. The accelerator is only 24m long and is being built to be modular and capable of changing proton beam energy and intensity pulse-to-pulse at up to 200Hz. The LIGHT prototype is currently being commissioned by AVO / ADAM at CERN, while the first full installation is foreseen in 2019. Here we present the design and implementation of a moveable diagnostic test bench which is used to measure a full set of beam properties at each commissioning step. Parameters measured include beam current, pulse length, energy, position, transverse profile and emittance. The compact instruments, the electronics and the controls that equip the test bench are the same as those who will be permanently installed along the accelerator after the commissioning. The first results obtained with the test bench for beams up to 16 MeV are shown here. We demonstrate that the chosen instrumentation achieves a very high sensitivity, dynamic range, reliability and immunity to EM noise. Procedures for on-line calibration of the instruments are also discussed.
