Abstract
The proton depth dose profile measured by luminescent detectors differs from the one measured with reference
dosimeters (i.e. ionization chambers) because of several effects including efficiency quenching and changes in
the attenuation of the emitted light in case of partial detector irradiation. Using the Microdosimetric d(z) Model
in combination with the Monte Carlo radiation transport code PHITS, a methodology was developed to tackle all
these factors and calculate the response of luminescent when exposed at different positions along a proton Bragg
peak. The results were compared against experimental data gathered with 7LiF:Mg,Ti (MTS-7) and 7LiF:Mg,Cu,P
(MCP-7) thermoluminescent detectors, showing a very good agreement (average relative deviation ~ 3% for
both detector types, smaller than the combined experimental uncertainty).
