    摘要： A klystron tube for amplifying signals at microwave radio frequencies utilizes an electron source for emitting electrons through a field focused by a high energy magnet in the RF section of the tube. After the electrons have passed through the active area of the tube, the electrons strike the collector which, in this case, is a multistage depressed collector. The multiple stages of the depressed collector are connected to high energy voltage sources of different potentials. The magnet used for focusing the electron beam is closed (no open pole pieces) at the multistage depressed collector so that no magnetic flux reversals are present to affect the beam dispersal, due to electrostatic space charge forces, onto the multistage depressed collector.

    摘要： An electron gun arrangement includes an electron gun having a longitudinal axis and including first and second electrodes longitudinally spaced apart for generating an electron beam in a longitudinal direction. A first support member supports the first electrode and includes a first slot arrangement presenting a first pair of surfaces longitudinally spaced apart. A second support member is longitudinally spaced apart from the first support member for supporting the second electrode and includes a second slot arrangement presenting a second pair of surfaces longitudinally spaced apart. The surface of the first pair of surfaces that is closer to the second support member constitutes a first clamping surface and the surface of the second pair of surfaces that is closer to the first support member constitutes a second clamping surface. Each of a plurality of spacer members made of electrically non-conductive material includes a first portion disposed in the first slot arrangement and abutting the first clamping surface and a second portion disposed in the second slot arrangement and abutting the second clamping surface for maintaining a distance in the longitudinal direction between the first and second clamping surfaces substantially constant and allowing movement between the respective support members in a direction transverse to the longitudinal axis due to differential thermal expansion.
