A NEW THERMAL DETECTOR.
Abstract
As part of a study of the dynamic properties of phase transition of ordered magnetic states, experiments have been performed that involve measuring the susceptibility of magnetic materials as the applied magnetic field is varied about a value for a critical phase tran sition to occur. This measurement technique has suggested a new thermal detector that, on the basis of preliminary calculations, promises to have an excellent NEP(10 to the minus 10 power - 10 to the minus 11 power) and whose output would be a frequency proportional to heat input. In addition this detector would provide; high level voltage output, output information rate approximately equal to the material time constant, and no requirement for ohmic leads. Theory of operation of the detector, including design factors and a summary of progress to date are given. A development program is also suggested. (Author)
