A search for resonant absorption of solar axions by ¹⁶⁹Tm nuclei will be performed using the Tm-containing bolometers installed inside a low-background setup at the LNGS.
Thulium crystals - NaTm(WO₄)₂ and NaTm(MoO₄)₂ have been grown and tested for the first time as bolometric detectors. The expected sensitivity of 1 kg Tm-bolometer to axion-photon (g _A γ) and axion-electron (g _{A e}) coupling constants for axions with mass in the range 10 eV to 8 keV is stronger than the present astrophysical limits.
