SURFACE DISCHARGE BASE PINCH-EFFECT DEVICE (ALTERNATIVES) Russian patent published in 2003 - IPC

FIELD: high-temperature plasma engineering. SUBSTANCE: device that may be used for pinch effect to generate, for example, high-power X-ray pulses has electrodes separated by insulator and switch-mode power supply connected to electrodes. Insulator is made in the form of dihedral angle with aperture facing switch-mode power supply; electrodes are disposed on dihedral angle faces and pass along lines intersecting on its edge. In second alternative insulator is made in the form of tetrahedral angle with aperture facing switch-mode power supply; electrodes are disposed on opposite faces of tetrahedral angle and come in contact with adjacent ribs. In first alternative each electrode is provided with pair of pointed projections inside dihedral angle disposed on different edges of this angle so that each projection has its pointed end facing projection of other electrode disposed on same face of angle; in second alternative each electrode has pair of pointed projections inside tetrahedral angle disposed on opposite faces of this angle adjacent to those carrying electrodes proper so that each projection has its pointed end facing projection of other electrode disposed on same face of angle. EFFECT: preventing development of wriggle and kite instability. 4 cl, 2 dwg
