Abstract:

A program of fabrication of four image tubes using InAsp transmission photocathodes sensitive to 0.965 micron radiation is described. These tubes were intended for imaging parametric upconversion experiments. A number of anticipated difficulties were encountered, and the sensitivity of the tubes shipped was a factor of only ten higher than commericially available image tubes, rather than the factor of 100 believed to be available under the most favorable conditions. The background noise was high, indicating the need for further improvements in tube and process design.
