Proton and Carbon Linacs for Hadron Therapy
Beams of 200 MeV protons and 400 MeV/u fully stripped carbon ions are used for the treatment of solid tumours seated at a maximum depth of 27 cm. More than 100’000 patients have been treated with proton beams and more than 10’000 with carbon ions. Very low proton currents of the order of 1 nA are enough to deliver the typical dose of 2 Gy/l in one minute. In the case of carbon ions the currents...
متن کاملProspects of target nanostructuring for laser proton acceleration
In laser-based proton acceleration, nanostructured targets hold the promise to allow for significantly boosted proton energies due to strong increase of laser absorption. We used laser-induced periodic surface structures generated in-situ as a very fast and economic way to produce nanostructured targets capable of high-repetition rate applications. Both in experiment and theory, we investigate ...

O. Deppert1, K. Harres1, F. Nürnberg1, G. Schaumann1, M. Schollmeier2, and M. Roth1 1Institut für Kernphysik, Technische Universität Darmstadt, Germany; 2Sandia National Laboratories, Albuquerque NM, USA The irradiation of thin metal foils by an ultra-intense, relativistic laser pulse leads to the generation of a highly laminar and intense proton beam accelerated from the target rear side by a ...
متن کاملHigh-intensity laser-driven proton acceleration: influence of pulse contrast.
Proton acceleration from the interaction of ultra-short laser pulses with thin foil targets at intensities greater than 10(18) W cm(-2) is discussed. An overview of the physical processes giving rise to the generation of protons with multi-MeV energies, in well defined beams with excellent spatial quality, is presented. Specifically, the discussion centres on the influence of laser pulse contra...
متن کاملInfluence of transverse laser beam profiles on proton acceleration
The irradiation of foil targets with ultra-intense short laser pulses leads to the generation of an MeV ion beam from the non-irradiated target rear side [1]. The accelerating mechanism was identified to be the build up of a dense sheath of energetic electrons at the non-irradiated, rear surface of the target with an electric field strength exceeding 10 V/m. The acceleration was found to take p...
