High Efficiency Transverse D. C. Electron Beams.
Abstract
The proposed new sintered metal oxide-metal (e. g. Al2O3-Mo) cathodes were tested. As originally predicted these cathode materials produce high current beams (1A) at multikilowatt posers in atmospheres containing a pure novel gas or a mixture of a novel gas and a metal vapor at generation efficiencies up to 75%. In contrast with other cathode materials previously used, the sintered materials allow multikilowatt electron beam operation in an oxygen free atmosphere. This is an important development in the construction of an cw electron beam excited UV laser, where no oxygen can be tolerated. These new electron guns developed for laser excitation find also important applications in other areas of research, such as the processing of microelectronic materials. Keywords include: High efficiency transverse D.C. electron beams.
