Abstract
This paper discusses the characterization of a cylindrical microwave resonant cavity used as a deflection system of convert tube. In the cavity two TM110 mode fields vertical to each other are excited and the electron beam is deflected by their magnetic field. Unlike usual deflection system of convert tube in which electron beam is deflected by electric field, this system has some special characters. Calculation shows this system introduces less spatial and temporal aberration, with almost no effect on the image quality, and the scanning speed can be very high. Also confining the field in a cavity, this deflection system has no edge field, which should be considered in metal plate systems. This system can be used in a circle-scan time analyzer and synchroscanner, or more in frame tube under some conditions.
