Abstract

This work is devoted to the project of a new-generation open trap, gas-dynamic multiple-mirror trap (GDMT), proposed at the Budker Institute of Nuclear Physics, Siberian Branch, Russian Academy of Sciences. The aim of the project is to substantiate the possibility of using open traps as thermonuclear systems: a source of neutrons and, in the future, a thermonuclear reactor. The main objectives of the project are to develop technologies for long-term plasma maintenance in an open trap, optimize neutron source parameters based on the gas-dynamic trap, and demonstrate methods for improving plasma confinement. The magnetic vacuum system of the facility consists of a central trap, multiple-mirror sections that improve the longitudinal plasma confinement, and expanders designed to accommodate plasma flux absorbers. The facility is to be built in several stages. The starting configuration is broadly similar to the GDT facility and includes a central trap with strong magnetic mirrors and expanders. It solves two main problems: optimization of the parameters of the neutron source based on the gas-dynamic trap and study of the physics of the transition to the configuration of a diamagnetic trap with a high relative pressure β ≈ 1, which significantly increases the efficiency of the system. This work describes the technical design of the starting configuration of the facility and outlines the physical principles on which the GDMT project is based.

气体动力学多镜阱GDMT

这项工作致力于俄罗斯科学院西伯利亚分院布德克核物理研究所提出的新一代开放式陷阱——气体动力学多镜陷阱（GDMT）项目。该项目的目的是证实使用开放式陷阱作为热核系统的可能性：中子源，以及未来的热核反应堆。该项目的主要目标是开发开放式阱中长期等离子体维护的技术，基于气体动力学阱优化中子源参数，并演示改进等离子体约束的方法。该设施的磁真空系统由一个中心阱、多个改善纵向等离子体约束的反射镜部分和设计用于容纳等离子体通量吸收器的膨胀器组成。该设施将分几个阶段建造。启动配置与GDT设施大致相似，包括一个带有强磁镜和扩展器的中央陷阱。它解决了两个主要问题：基于气体动力学阱的中子源参数优化和向高相对压力β≈1的反磁阱结构过渡的物理研究，显著提高了系统的效率。这项工作描述了设施启动配置的技术设计，并概述了GDMT项目所基于的物理原理。
