BULLKID-DM, based on the BULLKID detectors R&D is a new sub-GeV dark matter detector to be installed in the Gran Sasso underground laboratory. Gran Sasso is the largest underground, low radioactivity laboratory in the World. The goal of BULLKID-DM is to occupy a currently « empty » region in the energy-resolution versus target mass phase space as shown below.
The detectors are (of course) KID, machined as follows:
