Abstract

The invention relates to a parallel wire-array Z-pinch load which comprises an anode sleeve, a cathode sleeve, an anode plate, a cathode plate, a wire array, an insulating positioning sheet, two springs, two double-step positioning rods and two spring positioning rods, wherein the anode plate is fixed in the anode sleeve; the cathode plate is fixed in the cathode sleeve; and the wire array is arranged between the anode plate and the cathode plate. The invention solves the technical problem that the current column load is subjected to magneto fluid mechanics to cause instability in the pinch process to an axis, and the invention has the advantage that tight and uniformly distributed parallel wire-array Z-pinch load is provided in a pinch experiment.

Description

technical field

[0001] The invention relates to a test device for generating X-rays, in particular to a Z-pinch load of a parallel wire array, which is used for simulating strong X-rays produced by nuclear explosion radiation in Z-pinch experiments. Background technique

[0002] High-power Z-pinch is one of the current research hotspots. It can not only be used in the research of inertial confinement fusion, but also can generate strong soft X-rays, which can be used in the simulation of nuclear weapon physical effects, etc., and has broad application prospects. The Z-pinch load is a key component of the pinch experiment. It is used to form an array of metal wires. The metal wires form plasma under the action of high-voltage and high-current pulses, and then radiate strong X-rays to simulate X-ray radiation during nuclear explosions.

[0003] In traditional Z-pinch experiments, columnar loads are generally used for experiments. For example, the Z-pinch experiment currently ...

Embodiment Construction

[0027] refer to figure 1 As shown, the assembly of the wire array load is completed in a clean room and transported to the experimental site for installation. During preparation, the cathode thread of the double-step positioning rod 6 passes through the threaded hole of the anode plate and is screwed into the threaded hole of the cathode plate, and the threaded end of the spring positioning rod passes through the limit hole of the insulating positioning piece and the spring 8, and then is screwed on the cathode plate In the threaded hole, fix the double-step positioning rod 6 and the spring positioning rod 7, and pre-compress the spring 8. The compression distance is greater than the shrinkage distance between the cathode and anode plates. After the preparation is completed, the metal parallel wire array is wound. The metal wire fixing column can fix each metal wire on the outer surface of the anode plate or the outer surface of the insulating positioning piece. The double-ste...
