The device comprises a vacuum plasma target chamber, a pulse current generator, an annular laser spot generation device and a digit delay generator, wherein a load high-voltage electrode and a load ground electrode matched with the load high-voltage electrode are installed inside the vacuum plasma target chamber; a hole is formed in the load ground electrode; a transparent window is formed in the wall of the vacuum plasma target chamber; the load high-voltage electrode, the hole in the load ground electrode and the transparent window are coaxially arranged; the pulse current generator and the input end of the annular laser spot generation device are connected with the digit delay generator; the output end of the pulse current generator is connected with the load high-voltage electrode; a light outlet of the annular laser spot generation device and the transparent window are coaxially arranged. The method and device avoid an uneven structure and the like of a guide plasma caused in the process of forming the shell plasma column through cold and solid materials, and at the same time, the load structure is simpler, installation is convenient, and parameters are adjusted conveniently.

Description

technical field [0001] The invention belongs to a plasma generating device, in particular to a method and device for generating a shell plasma column. Background technique [0002] Z-pinch is a high-temperature and high-density plasma radiation source. Its basic principle is that the load is pulsed and discharged under a large pulse current to generate plasma. The plasma is driven by the current from the magnetic field Lorentz force to the axis and accelerates to implode. The pulse power device The electromagnetic energy of the plasma is converted into plasma kinetic energy; the high-speed moving plasma finally collides and stagnates at the axis to generate high-temperature and high-density plasma radiation, and the plasma kinetic energy is converted into radiation energy. Z-pinch plays an important role in the fields of inertial confinement fusion (Inertial Confinement Fusion, ICF), high energy density physics, laboratory astrophysics and X-ray radiation simulation.
