Matrix Cathode Development

Abstract

In order to correlate the efforts made by the three laboratories, three meetings between the respective responsible personnel were held during this phase of the program. The results obtained show the potential of the new cathode, since high current levels at relatively low operating temperature have been observed under cw and pulse operation. The current decay during pulse operation is less pronounced than in oxide cathodes, the emission homogeneity is excellent when compared to tungsten impregnated cathodes, and the inherent high ductility of the cathode material leads to inexpensive production fabrication of cathodes, especially of those requiring highly complex geometry and tight tolerances.
