Descripción
The direct detection of sub-GeV dark matter particle poses a major experimental challenge, since the non-relativistic kinetic energy of the candidates translate into an energy transfer between the impinging particle and the target media from few millielectron-volts to few electron-volts. A low-threshold athermal phonon calorimeter concept will be introduced in this talk to cope with such challenge.
The main goal is to achieve a sensitivity such that a single athermal phonon, created by the interaction of the dark matter candidate with the target material, can be detected with very high efficiency. This last technology is also suitable for the detection of so-called bosonic dark matter, such as a dark photon, an axionlike particle or a scalar particle with masses down to 1meV.
The multidisciplinary research team contributing to this proposal is coming from the IMB-CNM, ICMAB, IFCA and INMA groups, providing complementary expertise.
