Characteristics of 600 kV Class Ultra High Voltage Electron Beam Heat Source
Search this Article
An ultra-high voltage electron beam heat source with an electron gun employing multi-stage electromagnetic accelerating units was developed. The characteristics of the electron beam were studied and it was found that a strongly focused electron beam with an ultra-high average beam power density of 14000kW/cm^2 was successfully generated. Applicability of this ultra-high voltage electron beam to welding was investigated and it was found that this beam has high efficiency and allows to make a narrow weld bead.
