Transient Thermal Response of the Cathode Surface of a Potted Heater-Cathode Structure

Abstract

This brief presents the experimental transient thermal profiles of the cathode surface of a practical potted heater cathode structure (standard 250 Spectra-Mat heater-cathode packaging). Temperature-time history has been obtained experimentally for various input heater power levels. The experimental results have been compared with the theoretical predictions earlier reported [3], and it has been found that in all the cases, the theoretical predictions are within 10% of the experimental results, thus validating the earlier reported theory. © 1994 IEEE.
