The energies recommended by IAEA TRS 398 for therapeutic hadron beams range from 50 to 250 MeV for protons and from 100 to 450 MeV/u for carbon ions. At present such energies are supplied by conventional cyclotron, synchrocyclotron, synchrotron and linac type accelerators. As an alternative to conventional accelerator beams, laser-driven carbon ion/proton therapy beams have been developed. The parameter which characterizes the interaction of the clinical particle beams with the target is represented by the absorbed dose in the tumors. This paper presents a procedure for measuring the electric charge with ionization chambers as to determine the absorbed dose in clinical hadron beams.
