Abstract:

Before proceeding to convergent cathodes, it was modified as indicated. The first portion of this contract concentrated on reproducing the prior art of tungstate cathodes in a planar device. To summarize, while the emission has been reached for a brief period of time, the longer term emission is only about one-half of that expected. A program for improving the emission is still underway. In the meantime, two diodes with curved electrodes have been prepared. Also, a beam tester has been designed and is partially built. Author
