The relative TL efficiency of LiF:Mg, Ti and LiF:Mg, Cu, P was evaluated for several ion beams, ranging from helium to xenon ions. Irradiations were realized at the HIMAC accelerator in Chiba, Japan, partly within the ICCHIBAN intercomparison project. The covered LET range was extending from about 2 keV/μm to 1500 keV/μm.Both tested TLD types exhibited a decrease of relative response with increasing ionization density – stronger for LiF:Mg,Cu,P detectors. The relationship between efficiency and LET was found to follow unique trend lines, as nearly all data points lied within 5% around the fitted empirical functions. Values of TL efficiency measured for various batches of same type TLDs agree within a few percent. The measured relationships between relative TL efficiency and LET will be used in the analysis of data obtained from space dosimetric experiments.
