APPLIED RESEARCH ON TECHNIQUES FOR LIGHT MODULATION DETECTION

Abstract

Effort was continued on a study of convergent gun microwave phototubes. Present work was devoted principally to development of photocathode fabrication, and acquisition of light modulator components. Two procedures for fabricating Ag-O-Cs semitransparent photocathodes were studied, with considerably higher sensitivities resulting from one than the other. A new gun design was developed, a confined-flow type instead of a shielded-cathode type. This gu appears o b able to satisfy the condition of equal transi i s for all electrons better than any other. Most of the components for a microwave modulated light source were fabricated or acquired; assembly and operation will soon take place. (Author)
