Abstract
Abstract An electron tube is disclosed having at least one grid positioned between the cathode and the chamber anode with the chambers thereof formed by fins arranged parallel to one another and perpendicularly to the anode surface opposite the cathode. Each chamber is of a width given by the following formula: WHERE B WIDTH OF THE CHAMBER, Ua anode voltage other than zero, Delta Umin a difference between anode voltage Ua and the minimum chamber potential, i.e., a potential drop in the chamber, J AVERAGE DENSITY OF THE MAXIMUM ANODE CURRENT WHICH FLOWS VIA A SURFACE PASSING THROUGH THE CENTRE OF THE CHAMBER PERPENDICULARLY TO ITS LATERAL INSERTS, CH HYPERBOLIC COSINE, A DEPTH OF THE CHAMBER.
