For these reasons, in 2008 ADAM SA started their R&D activities in collaboration with CERN, Geneva to produce innovative and compact, high frequency, linear accelerators in order to reduce these costs, allowing more protontherapy centres to be accessible to as many hospitals as possible.
LIGHT. xxxxxxtableau 5(Linac for Image Guided Hadron Therapy) developed by ADAM SA brings together the physics and medical requirements to ensure correct treatment of cancer tissues with proton beams, and importantly, it also brings innovations in concept, design and manufacturing to reduce production costs.
The main characteristic features are:
Precision: the system has an active longitudinal modulation along the beam propagation axis (beam energy can be electronically varied during therapy and therefore the treatment depth), rather than using a passive modulation system (where the cyclotrons fixed initial energy is degraded through the interposition of variable thickness energy absorbers between the accelerator and the patient, causing a quality loss of the beam). Moreover, the LIGHT system has a dynamic transversal modulation that allows a precise 3D treatment of the tumours (spot scanning)
Compact: the linear accelerator LIGHT, in substitution of a cyclotron or synchrotron, has compact dimensions, therefore reducing size and costs of the building construction.

30-230MeV LIGHT accelerator
Modularity: the linear accelerator LIGHT is conceived as an assembly of modular units. This specific feature offers to radiation therapy centres complete freedom of customizing, steering medical choices on a wide range of treatment energies. Moreover, LIGHT enables small hospitals the initial choice of a 70 MeV accelerator for eyes, head and neck treatment, without precluding the possibility to extend it to higher energies by means of a simple installation of additional units, without dismantling then re-installing a completely new system (as is needed for cyclotrons and synchrotrons).
Easy maintenance: modularity and compactness, associated with straightforward design principles, allow fast and low cost maintenance during the short shut-down periods of the system, giving the possibility to achieve an overall system availability of >95% required by critical medical installations in hospitals.
User friendly: proton beam linear accelerators are similar in use to the conventional X-Ray linear accelerators currently used for cancer treatment. This similarity offers to doctors and medical technicians a familiar approach to using LIGHT.
