ABSTRACT:
In electron beam discharge tubes breakdown in the form of a gaseous arc can occur. An improved form of electrode which protects an insulating support against local high-stress fields is described. The electrode has a conductive shield extending to the other side of an interface between the electrode and the insulating support. A mechanism, the "single surface multipactor effect," which could cause the breakdown is also described.
