Abstract

The invention relates to the technical field of magnet coils for linear plasma devices, and specifically discloses a set of magnet coils for linear plasma devices. It includes a large-diameter coil group, a transition coil group and a small-diameter coil group, a total of three sets of magnet coils to meet the needs of different research tasks of linear plasma devices. The magnet coil makes full use of the flange gap, and by independently adjusting the current of each magnet coil, it can generate a high-strength and low-ripple magnetic field to fully confine the plasma. The magnetic field strength on the axis of the vacuum chamber reaches 1800-3000 Gauss. The waviness is less than 1%, especially in the transition area of ​​the magnet coil groups with different diameters, the magnetic field waviness is also less than 1%. It can be used for a large-scale, steady-state, high-beam current, linear magnetic confinement plasma device for comprehensive plasma-material interaction experiment detection of samples and components.

Description

technical field [0001] The invention belongs to the technical field of magnet coils, and in particular relates to magnet coils of linear plasma equipment. Background technique [0002] Linear plasma devices play an important role in the experimental study of plasma-material interaction, which is a key issue in the development of practical fusion reactors. In recent years, several sets of linear plasma devices have been built in China. For example, the Hefei Institute of Plasma and Lanzhou Institute of Chemical Physics of the Chinese Academy of Sciences each built a set of plasma fluxes up to 10 20 -10 21 / m 2 The linear plasma device of .s is mainly aimed at the retention research of gases such as hydrogen isotopes; the STEP device of Beijing University of Aeronautics and Astronautics has a large nominal plasma parameter span of up to 10 19 ~10 23 / m 2 .s is currently mainly used for teaching and basic experiments; the device in Sichuan University 720 is said to have a ...
