From Dark Matter to Brittle Fracture
Prompted by the intriguing results obtained by some of the rare-event searches looking for the dark matter that may make up the bulk of the matter in the Universe, we have studied brittle fracture as a background in scintillation detectors. Under conditions of ambient temperature and pressure, we have demonstrated a correlation between fracture, acoustic emission, and emission of light in several common scintillators. We present early results from an improved setup. When commissioned, it will provide additional channels to study these phenomena, in controllable atmospheres.
