Kaufman & Robinson offers several types of low energy and high current electron sources. The source technologies vary from simple immersed thermionic filaments to non-immersed hollow cathode emitters. Typically, these electron sources can function as both a cathode and/or neutralizer in conjunction with a plasma or ion source. Their operation in inert and reactive gas environments is standard. The emission current from our electron source products is measured and controlled with a current feedback loop. Because of this precise and reliable source of electrons, the KRI electron sources are successfully used in electrostatic sensitive applications and dielectric material environments.
Kaufman & Robinson offers a comprehensive electron source product package. The package is complete with components required to install and operate the electron source products, including the electron source, power supply controller, mass flow controller, vacuum feedthroughs, and cables.
Typically, the KRI electron source products are installed in a materials processing environment. Commonly, they are integrated as neutralizers onto ion beam sources or they may be integrated into the ionization process of a plasma discharge. In other, more specialized applications, they can be installed with magnetron cathodes to modify the sputtering operation.
