摘要
This article reports on design and application of wide-aperture pulsed beam source, based on hollow cathode discharge. The source is intended for electron beam generation in pressure range 2-15 Pa. Multi-aperture extraction system, used in a source, provided beam cross-section uniformity of 10% on diameter 40 mm. The limiting values of the current density, pulse duration, and accelerating voltage are 350 mA/cm(2), 250 mu s, and 10 kV, respectively. These parameters are sufficient for surface modification of various materials, including non-conducting matters. (C) 2013 American Institute of Physics. [http://dx.doi.org/10.1063/1.4789771]
