TL;DR: The Dynamitron high-current accelerator is described in this article, illustrated with a photograph of a 3.0 Mv unit, and circuit diagrams of the rectifier cascade are presented and performance data are compared with formulas for internal impedance and power consumption.
Abstract: A description of the Dynamitron high-current accelerator is given, illustrated with a photograph of a 3.0 Mv unit. Simplified circuit diagrams of the rectifier cascade are presented and performance data are compared with formulas for internal impedance and power consumption. Brief descriptions of the ion source and the beam tube are also given. Possibilities for future development of the accelerator and accessories are discussed. These include higher voltage, higher beam current, terminal pumping, terminal mass analysis, nanosecond beam pulsing, high intensity pulsing, high energy negative ion production and dual purpose tandem accelerators.

TL;DR: In this article, a microproton beam line with a doublet quadrupole and a slit-system of microslits, divergence-defining slits and baffle slits connected to the 4.5 MV Dynamitron accelerator was constructed at Tohoku University.
Abstract: A microbeam system is under construction in the Dynamitron laboratory at Tohoku University for the purpose of applying X-rays produced by a microproton beam as monochromatic X-ray point source to biological and materials research etc. The system consists of a dedicated beam line with a doublet quadrupole and a slit-system of microslits, divergence-defining slits and baffle slits connected to the 4.5 MV Dynamitron accelerator’s energy analyzing system, which was a newly installed second analyzing magnet. The demagnification factors are 8.0 and 27.5 for horizontal and vertical planes, respectively. Performance of the microbeam system was tested by beam scanning across the surface of a copper mesh sample (1000 lines/inch) and measuring the X-ray spectrum. A beam spot size of 2 × 2 μm 2 , which is larger than the design goal, is currently obtained. We are now adjusting the whole system to achieve a beam spot size of 1 × 1 μm 2 .

TL;DR: In this article, the DynamitronR accelerator has been improved to achieve higher electron beam energy and power ratings, achieving more than 200 kW of dc beam power at 5.0 MeV.
Abstract: In response to increasing interest in X-ray processing of medical devices and food, the design of RDI's DynamitronR accelerator has been improved to achieve higher electron beam energy and power ratings. During factory tests, the prototype has produced more than 200 kW of dc beam power at 5.0 MeV. When equipped with an optimized high-Z target, the X-ray emission is expected to be about 15 kW and the processing rate is expected to be equivalent to about 1.6 MCi of 60Co.
