The proposed accelerator facility for light ion cancer therapy in Heidelberg

The main characteristics of this facility are the application of the rasterscan method with active intensity, energy and beam size variation in combination with the usage of isocentric light ion gantries. The accelerator is designed to accelerate both low LET ions (p,He) and high LET ions (C,O) to cover the specific medical requirements. Major aspects of the design are influenced from the experiences of the GSI cancer treatment program; the requirements of this facility, however, exceed in many fields those of this GSI therapy program.
