Dynamitron

The Dynamitron is an electrostatic particle accelerator invented by Marshal Cleland in 1956 at Washington University in St. Louis and manufactured by IBA Industrial (formerly Radiation Dynamics).

[6] However instead of being powered at one end as in the Cockcroft-Walton, the capacitive ladder is charged in parallel electrostatically by a high frequency oscillating voltage applied between two long half-cylindrical electrodes on either side of the ladder column, which induce voltage in semicircular corona rings attached to each end of the diode rectifier tubes.

[2] in combination with an inductor this structure forms a resonant tank circuit for the oscillator providing the voltage, at a frequency of 100 kHz.

The Dynamitron is made in several models with output energies from 0.5 to 5 MeV and beam power from 50 to 200 kW.

[2] Its main use is in industrial irradiation applications; the most common are polymer crosslinking for production of heat shrink tubing, and shrink wrap plastic film for food packaging, sterilization, and curing of plastic foam and tire components.
