We present an approach to use Al2O3:C,Mg-based fluorescent nuclear track detectors (FNTDs) and confocal laser scanning microscopy as a semiautomatic tool for fluence measurements in clinical ion beams. The method was found to cover a linear energy transfer (LET) range from at least L∞(Al2O3) = 0.5 keV/μm to 61,000 keV/μm with a detection efficiency ≥99.83% (20 MeV protons) at particle fluences up to at least 5 × 107 per cm2. Our technique allows to determine the spatial fluence distribution on a microscopic scale and enables detailed track-by-track comparison studies between different fluence detectors.
► We implemented a semiautomatic tool for fluence measurements using Al2O3:C,Mg-based FNTDs.
► The method covers the linear energy transfer range in Al2O3 from at least 0.5–61,000 keV/μm.
► The upper fluence limit was found to be around 5 × 107 per cm2.
► We determined the single particle detection efficiency of FNTDs to ≥99.83%.
► Our method allows to determine spatial fluence distributions on a microscopic scale.
