The MedAustron project

The Austrian government has approved its financial contribution to the MedAustron project in October 2004. MedAustron, the Austrian ion therapy and cancer research centre, should be set into operation in 2010. MedAustron combines medical cancer treatment and cancer research and non-clinical research.For medical treatment and cancer research active scanning of a proton and a carbon-ion beam is provided. The beam energy must correspond to the desirable penetration range of the beam in the patient body, which translates into the energy interval of 60–220 MeV protons and 120–400 MeV per nucleon carbon ions. The intensity of extracted beam is 1010 protons per spill and four times 108 carbon ions per spill. Spill duration can be varied from 1 s to 10 s. For a spill lasting 1 s the beam intensity is equivalent to an electrical beam current of 1.6 nA for protons and 0.38 nA for carbon ions.Although the machine parameters must be optimised for therapy needs, additional beam features can be offered by a modern medical accelerator for non-clinical research. Various ions with energies up to 400 MeV per nucleon can be used for irradiation purposes. For synchrotrons such as proposed in the Design Study the magnetic rigidity would allow to accelerate protons up to 1.18 GeV when using an appropriate RF-system. Two beam lines are proposed for non-clinical research, such as biomedicine, medical physics, physics or industrial technological research. The experimental facility of MedAustron will be offered to research institutes and to industry on an international level.
