Abstract:

Each of the nine program tasks is discussed in some detail. The most significant aspects are failure modes in the TR-316 transducer design and the testing techniques used to discover them, the quantification of corona levels on ceramic and in wet and dry SF6, accelerated reactions of polymers in water, and the discrimination of transducer self-noise and spurious system noise.
