HOLLOW CATHODES IN NEGATIVE-GRID TUBES,
Abstract
This study involved factors important to the successful operation of hollow cathodes in negative-grid tubes: (1) activation rate; (2) mechanism of operation; and (3) grid action with truncated pyramidal hollow cathodes. A method of reducing the activation rate by ten-fold was investigated and achieved. The mechanism of operation was studied utilizing sectionalized cathodes. Results tend to confirm the theoretical model postulated by Babcock, et als. Unusual grid-control characteristics associated with hollow cathodes were experimentally derived and indicated the basis for the observed transconductance limitation. (Author)
