  To investigate fractoluminescence in scintillating crystals used for particle
detection, we have developed a multi-channel setup built around samples of
double-cleavage drilled compression (DCDC) geometry in a controllable
atmosphere. The setup allows the continuous digitization over hours of various
parameters, including the applied load, and the compressive strain of the
sample, as well as the acoustic emission. Emitted visible light is recorded
with nanosecond resolution, and crack propagation is monitored using infrared
lighting and camera. An example of application to Bi4Ge3O12 (BGO) is provided.
