An electron gun is the electron injector of an accelerator, which emits an electron beam with a certain energy, current intensity, beam diameter, and emission angle into the accelerator tube. The function of an electron gun is to provide a satisfactory electron beam, which is typically used in Auger energy spectrometers (AES), energy loss spectrometers (ELS), and X-ray energy spectrometers (XPS)
We can provide various models of electronic sources, optimized for different application fields and analysis requirements. The energy range covers 10ev-125keV, and the beam spot diameter ranges from 20nm to 525mm, including various wide beam electronic sources, precision focused electronic sources, low-energy, and high-energy electronic sources, which can meet various purposes such as surface cleaning, surface sputtering, and space environment simulation.
