Title:
METHOD AND APPARATUS FOR IONIZING GAS
Document Type and Number:
Japanese Patent JPH01274396
Kind Code:
A
Abstract:
PURPOSE: To lead the ionized gas to a desirable point by leading the pressurized gas to the predetermined area along a surrounded flow passage, and ionizing the gas with radiation, and discharging the ionized gas from the surrounded flow passage in the predetermined area. CONSTITUTION: Flow of the pressurized gas from a gas supplying source 16 passes through a flow passage including a housing 18 having an inner chamber 19, to which ionizing radiation 21 is to be led, so that the pressurized gas is ionized, and the gas is transmitted to an ion chamber 12. An inlet opening 22 inside of a wall of the housing 18 communicates with the gas supplying source 16 through an inlet conduit 23, a filter 25 a flowmeter 24, and a flow control valve 26. As the gas to be used for ionization, the gas, which does not include oxygen, is necessary, and the inert gas such as nitrogen is used. X-ray 21 from an X-ray tube 29 ionizes the gas through a thin window part provided at a part of the inner chamber 19, and the ionized gas is supplied from a pipeline 28.
