Popis: The EDELWEISS collaboration reports on the search for dark matter particle interactions via Migdal effect with masses between 32MeV⋅c−2 to 2 GeV⋅c−2 using a 200 g cryogenic Ge detector sensitive to simultaneously heat and ionization signals and operated underground at the Laboratoire Souterrain de Modane in France. The phonon signal was read out using a transition edge sensor made of a NbSi thin film. The detector was biased at 66 V in order to benefit from the Neganov-Trofimov-Luke amplification and resulting in a resolution on the energy of electron recoils of 4.46eVee (102.58 eV at 66 V) and an analysis threshold of 30eVee. The sensitivity is limited by a dominant background not associated to charge creation in the detector. The search constrains a new region of parameter space for cross sections down to 10−29cm2 and masses between 32 and 100MeV⋅c−2. The achieved low threshold with the NbSi sensor shows the relevance of its use for out-of-equilibrium phonon sensitive devices for low-mass dark matter searches.
