Electrostatic accelerator up to 200 kV

摘要

In an electrostatic accelerator with a target to be subjected to a beam of electrically charged particles in the energy range of 200 keV in a closed vacuum system, and an ion source for generation of the charged particles, a staged accelerator structure is disposed between the ion source and the target and includes a number of drift tubes disposed adjacent to one another in axially spaced but aligned relationship so as to permit passage of the beam therethrough and a high-voltage multiplier is disposed annularly around the drift tubes and is divided into stages corresponding to the adjacent drift tubes to which the stages are connected for providing accelerator voltages thereto thereby providing for a compact overall structure.
