Abstract

A newly developed experimental technique based on 169Tm-containing cryogenic bolometer detector was employed in order to perform the search for solar axions. The inclusion of target material into the active detector volume allowed for significant increase in sensitivity to axion parameters. A short 6.6 days measurement campaign with 8.18 g detector crystal yielded the following limits on axion couplings: |gAγ(gAN0 + gAN3 ) ≤ 1.44 × 10-14GeV-1 and |gAe(gAN0 + gAN3 ) ≤ 2.81 × 10-16. The achieved results demonstrate high scalability potential of presented experimental approach.
