Resonators for Acceleration Environments.
Abstract
Singly rotated AT cut plates are most often used for frequency control in applications where moderate and high precision is required, but recent developments point to a greatly expanded role for doubly rotated cuts. Virtually all of these thickness mode cuts are of the form of thin circular discs mounted on their edges. Any forces communicated between the mounting supports and the quartz plate produce high stresses and stress-gradients resulting in significant frequency perturbations. This report describes crystal plate designs having a prescribed lateral contour for singly and doubly rotated plates. These designs provide a relatively large portion of the periphery for mounting, such that mounting stresses are greatly reduced with no detriment to the force immunity of the older-type mounts.
