Current study results on Nuclear Physics have been published. According to news reporting originating in Ibaraki, Japan, by VerticalNews journalists, research stated, "A C-band RF gun for compact radiation sources such as high-energy X-ray and terahertz radiation sources is developed at AIST and is designed to work at a frequency of 5.3 GHz."

The news reporters obtained a quote from the research from the National Institute of Advanced Industrial Science and Technology (NIAIST), "The total length of this equipment is about 1.5 m. An electron beam with a maximum energy of 0.9 MeV can be generated when the peak electric field is 85 MV/m, corresponding to an RF peak power of 600 kW. A coniferous-tree-type carbon nanostructure is used for the field emission cathode."

According to the news reporters, the research concluded: "We present the structural design and fabrication of the C-band RF cavity and a low-power RF test of it."
