Description

Gas-dynamic multi-mirror trap (GDMT) is an ongoing project in development at Budker Institute of Nuclear Physics, which aims to demonstrate a leap in performance for linear axisymmetric magnetic plasma confinement systems and lay the groundwork for a full-scale development of fusion neutron sources (NS) based on gas-dynamic plasma confinement. As a multipurpose facility, GDMT is being designed to experimentally evaluate a number of concepts, which promise a dramatic improvement in plasma confinement in linear systems. Superconducting magnet system of GDMT consists of a confinement region with magnetic field strength up to 3 T which is terminated by either single high-field (up to 18 T) magnetic mirrors or advanced multi-mirror modules, which provide necessary plasma flux suppression. Owing to its modular design, the system length can change from 6 m for studies of high-β plasma regimes to several tens of meters to accommodate for NS studies with maximized confinement zone length and most advanced multi-mirror modules. The design goal is to build a modular superconducting magnet system, which enables an easy reconfiguration of the confinement zone and attachment of mirror sections, while being mechanically robust and cryogenically efficient. The report outlines the scientific program of GDMT and reviews the experimental possibilities it provides to study a set of problems that are most critical to accelerated development of practical volumetric fusion neutron sources.
