Abstract: The application of laser accelerated ion beams in Hadron therapy requires ion beam optics with unique features. It has been shown that due to the spectral and spatial distribution of laser accelerated protons a lens based focusing system has advantage over aperture collimated beam formation.
We present a compact ion optical system with therapy applications, based on the Gabor space charge lenses for collecting, focusing and energy filtering the laser produced proton beam.
For a full therapy solution, a scenario based on three space charge lenses is presented.
In this very compact beam line an aperture is foreseen for energy selection.
