A real-time lithiated wall treatment system for improved plasma wall conditions

Abstract

The invention discloses a real-time lithiation wall processing system used for improving the wall conditions of plasma. The system comprises an evaporator, a baffle and control system and a corrugatedpipe conveying system, the baffle and control system comprises a rotary baffle; the baffle is arranged at an evaporation outlet of the evaporator; a rotary shaft of the baffle penetrates through theevaporator and extends to the outer end portion; a linear guide-in device is installed at the other end of the rotary shaft; the lower end of the linear guide-in device is connected to a nitrogen cylinder through a pipeline; the corrugated pipe conveying system comprises a supporting pipe installed on the rotary shaft at the rear end of the evaporator in a sleeving mode; the front end of the supporting pipe communicates with the evaporator; the rear end portion of the supporting pipe is sleeved with a corrugated pipe; and a gate valve and a lithium containing chamber are installed at the position, at the front end of the corrugated pipe, of the supporting pipe. The first wall surface is coated with lithium in real time during plasma discharging, the improvement of the plasma performance isachieved rapidly, economically and effectively, and the long-pulse and high-power plasma discharging of a magnetic confinement fusion device is conducted advantageously and successfully.

Description

[0001] Technical field: [0002] The invention relates to the field of modification of the first wall material inside a vacuum chamber of a magnetic confinement fusion device, and mainly relates to a real-time lithiation wall treatment system for improving plasma wall conditions, which performs real-time lithiation coating wall treatment in plasma discharge , to modify the surface of the wall material in real time, thereby improving the plasma quality. . [0003] Background technique: [0004] Future reactors are mainly faced with long-pulse steady-state operation, thermal load handling, high energy confinement, particle control and high-density discharge, and low effective charge. Lithium is currently found to be the most effective means of controlling particle recirculation. It can not only effectively control the plasma density, but also reduce impurities from the vessel wall. This is of great significance to any nuclear fusion device that operates in a steady state and can...
