Abstract
In a multistage collector used in a linear beam tube such as an IOT or klystron, electrode stages are separated by ceramic rings having metallised surfaces to provide distributed bypass capacitors. This eliminates or reduces leakage or any radio frequency energy from the interior of the collector to the outside.
