Dynamitron

The Dynamitron® is a particle accelerator developed by IBA Industrial, (formerly Radiation Dynamics) in the 1960s. Depending on configuration it can either accelerate electrons or positive ions.

The Dynamitron's accelerating column is contained within a pressure vessel filled with high pressure Sulfur Hexafluoride insulating gas. The column is composed of a number of rectifier tubes, assembled in cascades. Semi-circular corona rings are attached to the anode and cathode of each rectifier in the cascade. Two rf electrodes are mounted near the inner surface of the tank. This circuit, with a resonance frequency around 100 kHz, is coupled inductively with an oscillator. Because of its high power, the oscillator sits in a separate tank. Parallel coupling of the cascade to the liners is accomplished through the electrode to corona ring capacitance. The main advantage of this parallel coupling design is that it allows a much higher beam current to be transported than a typical Cockcroft–Walton style accelerator.
