Performance and potential capabilities of thermionic conversion devices

Out-of-Core Thermionic Space Power.

“…(The emitter and collector thicknesses are set at 2 mm and 1 mm, respectively.) The emitter surface power density used was obtained by adjusting the data ot Lieb and Rufeh (18) to the conditions where maximum efliciency is expected to occur, namely around 0,8 volt and a gap of about six mils. The result of a fit to this adjusted data is shown in Figure 7.…”
