Abstract
Several experiments are currently competing to directly detect sub-GeV/c2 dark matter through elastic scattering off various target nuclei. Hydrogen-rich materials, such as organic compounds, are promising candidate targets for such experiments due to favourable kinematics. In this paper, we present for the first time results ob tained with a sugar-based cryogenic particle detector. A sucrose (C12H22O11) monocrystal was instrumented with a neutron transmutation doped germanium thermistor to detect phonons from particle interactions, and was operated in the vicinity of a light detector. Particle interactions in the sugar were observed with associated scintillation light, indicating a possible channel for particle discrimination.
