A. Sil et al., TRANSIENT THERMAL RESPONSE OF THE CATHODE SURFACE OF A POTTED HEATER-CATHODE STRUCTURE, I.E.E.E. transactions on electron devices, 41(8), 1994, pp. 1480-1481
This brief presents the experimental transient thermal profiles of the
cathode surface of a practical potted heater cathode structure (stand
ard 250 Spectra-Mat heater-cathode packaging). Temperature-time histor
y has been obtained experimentally for various input heater power leve
ls. The experimental results have been compared with the theoretical p
redictions 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.
