    摘要: A plasma X-ray source in which a discharge tube containing a pair of coaxial cylindrical electrodes is filled with a gas, a high voltage pulse from a charged capacitor is applied between the cylindrical electrodes to convert the gas into a plasma, the plasma is focused on a position near the end of the inner one of the cylindrical electrodes to generate X-rays, and the X-rays thus generated are emitted to the outside of the discharge tube through a window provided thereon, is disclosed. In the above X-ray source, the high voltage pulse is applied between the cylindrical electrodes so that the inner cylindrical electrode is at a negative potential with respect to the outer cylindrical electrode.

    摘要: A plasma X-ray source comprises inner and outer cylindrical electrodes disposed coaxially and with a certain distance with respect to each other, an electrical insulator disposed between end portions of the inner and outer cylindrical electrodes, and a discharge vessel disposed to envelop the inner and outer cylindrical electrodes. A pulse voltage is applied between the inner and outer cylindrical electrodes to produce plasma in the discharge vessel. An electrically conductive spherical shield is disposed to envelop a space where the plasma is pinched, and the spherical shield is maintained at a potential equal to that applied to the outer cylindrical electrode.

    摘要: A plasma X-ray source is operable, like the plasma focus type source, to generate impulse discharge through a gas filled in a discharge tube. A relatively small amount of the gas is continuously supplied to and evacuated from the discharge tube in accordance with an occurrence frequency of discharge, without operating evacuation and filling of the gas at each cycle of discharge, under the regulation to make constant the pressure within the discharge tube, thereby eliminating the time for exchange of gas contaminated by discharge, reducing the amount of gas used, and improving reproducibility of discharge.
