Phonon-mediated detection of elementary particles using silicon crystal acoustic detectors

Thesis/Dissertation ·
OSTI ID:5232112
A research group at Stanford is developing Silicon Crystal Acoustic Detectors (SiCADs) which operate at cryogenic temperatures and sense phonons generated when an incident particle scatters off a nucleus or electron in the crystalline Si wafer substrate. In the present design photon sensors consist of a thin film labyrinth pattern of superconducting titanium, which is dc current biased at a temperature just below its superconducting to normal transition (approx. 430 mK). The motivation for developing SiCADs includes their many direct applications to neutrino physics, particle astrophysics, and solid state physics.
