Abstract

At the underground laboratory of Monte dei Cappuccini (OATo-INAF) in Torino (Italy) we set up selective HPGe-NaI(Tl) spectrometers for measurements of cosmogenic radioisotopes in meteorites in order to study centennial-scale modulation of solar activity. 44Ti is a suitable proxy for this timescale, but its detection is difficult due to the strong interference by naturally occurring 214Bi. In order to optimize the extraction of the 44Ti signal, we have developed software procedures specifically designed to improve selectivity of the Ge-NaI detectors coincidence.
