Field emitter array electron gun holding field emitter array cells by band

摘要

A FEA electron gun is disclosed in which a FEA cell is stably fixed to a support by a band.;In the prior art, when the FEA cell is fixed to the support, bonding is performed using a powder or ceramic bond, such as a frit, as the bonding material, or one end of the elastic pin is embedded in the insulating material support and fixed to the other end. In the former case, the gas generated from the bonding material adversely affects the normal operation of the FEA gun, and in the latter case, the process of assembling the FEA cell is not easy.;To solve this problem, one or more metal bands are used to secure one end to the side of the casing, wind the top of the FEA cell into contact with the other, and then secure the other end to the spring installed on the opposite side of the casing. Fixation was made.;As such, the FEA electron gun in which the FEA cell is fixed by the band can be used for various cathode ray tubes.
