Problems solved by technology

[0003] However, the traditional plasma jet device does not have an external controllable magnetic field, and the directionality of the microbeams produced by the plasma jet without control constraints is poor. At this stage, the plasma is not constrained and controlled by the magnetic field. At the same time The confinement force of the magnetic field cannot be changed. In actual operation, the occurrence of the plasma jet is relatively simple, and the accuracy of the plasma jet is poor. Therefore, it is difficult to control the generated plasma to achieve the ideal use effect, which cannot fully satisfy People's needs and applications in specific environments

Description

technical field [0001] The invention relates to the field of plasma technology, in particular to a variable magnetic field confinement plasma jet device and a method thereof. Background technique [0002] Plasma jet is an important application form of plasma, and has excellent application prospects in the fields of material modification, surface treatment, plasma chemistry and plasma medical treatment. In traditional use, by adjusting the external electric field and magnetic field, the energy is preferentially transferred to electrons instead of heavy particles, and the transferred energy is transmitted to heavy particles through the collision of electrons to excite and ionize, thereby producing highly active substances. The low pressure increases the mean free path of the electrons and thus enables them to gain sufficient energy. In practice, an external excitation source is used, and after plasma is generated in a limited cavity, the generated plasma is blown out of the d...
