Sensitive cryogenic transducer development and analysis for use on gravity wave detectors

Thesis/Dissertation ·
OSTI ID:5561192
The design and development of an improved superconducting inductively modulated transducer are discussed. The transducer is designed to optimize the performance of a 2-mode, resonant bar, gravitational wave antenna. A detailed theoretical analysis which includes are relevant noise sources is described. Conditions for optimizing 2-mode detector performance are derived, and design curves are presented. Based on the results of this analysis, an optimal transducer has been designed for use on the Louisiana State University gravitational wave detector. The fabrication and testing of several optimal mass 400gm transducer resonators are described. The effects of low temperature annealing on the mechanical Qs of the Nb resonators are discussed.
