- Abstract:
- Sampling represents an important phase of the procedure to perform authenticity test by thermoluminescence. The test could be compromised if this step is not properly carried out. In particular, if the local heating of the area subjected to the sampling by drilling reaches high temperatures, the signal results underestimated. In order to evaluate the increasing temperature during the sample collection in authenticity test, in this paper we propose a procedure useful for temperature in situ measurements using an indirect method. This method allows estimating the temperature dissipated during the drilling of the samples as consequence of the drill rotation. The temperature variation is obtained through the evaluation of an output voltage measured across a known reference resistor, in presence of a current.
