TL;DR: A novel code system, TRiP, dedicated to the planning of radiotherapy with energetic ions, in particular 12C, designed to cooperate with three-dimensional active dose shaping devices like the GSI raster scan system is described.

TL;DR: The attenuation of 4He primary particles and the build-up of secondary charged fragments at various depths in water and polymethyl methacrylate were investigated experimentally for 120 and 200 MeV u-1 beams delivered by the synchrotron at the Heidelberg Ion-Beam Therapy Center, Heidelburg.

TL;DR: target fragmentation was investigated indirectly by measuring low-noise proton Bragg curves with the focus placed on their build-up regions by means of simulations and experiments and it could be shown that the relevant models worked well to reproduce both building-up effects.

TL;DR: The experimental results show an increased shielding effectiveness of lithium hydride compared to reference materials like polyethylene, and the comparison results between both transport codes indicates that the standard Tripathi-based total reaction cross-section model of PHITS cannot accurately reproduce the presented experimental data, whereas GRAS shows reasonable agreement.

TL;DR: In this article, a fragmentation experiment using thin graphite targets was conducted at the Heidelberg Ion Beam Therapy Center (HIT) to obtain new and precise $4 \mathrm{He}$-nucleus cross section data in the clinically relevant energy range.
