BabyIAXO
The BabyIAXO experiment, lead byt the University of Zaragoza, will produce relevant physics while preparing the ground for the full infrastructure of the IAXO (International Axion Observatory) which is a new generation axion helioscope and its main goal is to detect axions (or other similar particles) potentially emitted by the Sun’s core in large quantities

Low-level γ spectroscopy with High Purity Germanium (HPGe) detectors has become an essential tool for material screening in rare event physics experiments, which demand the lowest radioactivity levels. Typical examples are searches for solar neutrinos, neutrinoless double beta decay and dark matter. Compared to other methods, such as mass spectrometry or neutron activation, spectroscopy provides a comprehensive method in a non-destructive way without complex sample treatment. The primordial radioisotopes 232Th, 238U and 40K represent the main sources of contamination in common materials. Concerning the two former isotopes, only HPGE spectroscopy can verify secular equilibrium as it is capable of measuring the concentration of their progenies near the end of their respective decay chains – in particular 208Tl and 214Bi.
