摘要: An X-ray source for ionizing of gases includes a field emission tip array within a vacuum region enclosed by a hood and a part of a support plate. The field emission tip array is arranged electrically insulated with respect to the carrier plate and wired as a cathode connected to a high-voltage source. A transmission window transparent to X-ray radiation is arranged in the hood centrally above the field emission tip array, and the hood is wired as an anode.
