Abstract:

Techniques were developed for constructing a convergent gun traveling-wave phototube. The procedure for transferring the photocathode from the fabrication vessel to the tube body has been tested and found successful. If care is taken, no loss of photosensitivity occurs during the transfer. This transfer technique greatly simplifies the construction of the phototube by eliminating the need for cathode fabon and positioning assemblies inside the photocathode. The light modulator design and construction has been completed and tested. With 1.3 watts of input rf power at 3420 mcsec, the modulation index is 0.1. This modulator, together with a superpressure Hg-arc light source, will be used to determine the rf characteristics of the phototubes.
