Acceleration sensitivity measurements of Quad Relief Mount langasite resonators

Abstract

This paper reports on the fabrication and testing of a langasite quad relief mount (QRM) resonator. It reviews the mechanical construction and assembly process for the resonator and an experiment is defined to explore the dependence on azimuthal Psi angle. Crystal parameters and acceleration sensitivity results are reported and demonstrate low acceleration sensitivity with little variation with azimuthal Psi angle. Finally, a comparison of the results to AT-cut and SC-cut are discussed and show that the langasite QRM resonator has great potential for achieving even better performance for acceleration sensitivity.
