ABSTRACT:
A high-power switch tube is shown constructed from a plurality of electron guns each gun having a cathode and an anode. Between the cathode and anode is mounted a shadow grid closest to the cathode beyond which is mounted a control grid, a screen grid, and, in some applications, by a suppressor grid. Each anode is formed with an anode cavity having an opening that is smaller in dimension than the largest dimension of the cavity thus forming a Faraday cage collector which prevents secondary emission problems.
