Dynamitron
The Dynamitron is an electrostatic accelerator, electrostatic particle accelerator invented by Marshal Cleland in 1956 at Washington University in St. Louis and manufactured by IBA Industrial (formerly Radiation Dynamics).Cleland, Marshal R., US Patent 2875394AVoltage multiplication apparatus filed: 29 October 1956, granted: 24 February 1959 , p.4 It is similar to a Cockcroft-Walton accelerator, using a series capacitor-diode ladder network to generate a high direct current, DC voltage on an electrode, which accelerates particles through an evacuated beam tube between the electrode and a target at ground potential. 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. i ...

Electrostatic Accelerator
An electrostatic particle accelerator is a particle accelerator in which charged particles are accelerated to a high energy by a static high voltage potential. This contrasts with the other major category of particle accelerator, oscillating field particle accelerators, in which the particles are accelerated by oscillating electric fields. Owing to their simpler design, electrostatic types were the first particle accelerators. The two most common types are the Van de Graaf generator invented by Robert Van de Graaff in 1929, and the Cockcroft-Walton accelerator invented by John Cockcroft and Ernest Walton in 1932. The maximum particle energy produced by electrostatic accelerators is limited by the maximum voltage which can be achieved the machine. This is in turn limited by insulation breakdown to a few megavolts. Oscillating accelerators do not have this limitation, so they can achieve higher particle energies than electrostatic machines. The advantages of electrost ...
