Phonon - mediated particle detection

When an incident particle collides with an electron or nucleus in an insulating crystal, the recoil kinetic energy is converted rapidly into a burst of low-energy phonons. If the crystal is very pure and free of defects, and if it is very cold, (T--0.1K), the phonons will propagate ballistically for distances of several centimeters. The authors report on experiments with two types of superconducting phonon sensors being considered for use on a new kind of particle detector, called a Silicon Crystal Acoustic Detector (SiCAD), which reads out phonons generated by particle scattering events.
