摘要

本文概述了对气体动态阱(GDT)中不同能量损失通道的实验结果,GDT 是布德克核物理研究所的一个磁镜等离子体约束装置。研究考虑了沿磁场线的能量损耗以及径向限幅器上的损耗,限幅器限制了等离子体柱的半径,并通过 "涡流约束 "机制提供了磁流体动力学稳定性。利用等离子体吸收器上的一组热释电波长计测量了场线上的损耗,并利用热敏电阻器根据等离子体限幅器的温升确定了限幅器上的损耗。此外,还使用安装在中心池壁上的热释电波长计纵向阵列测量了快速等离子体离子对 GDT 中残余中性气体的电荷交换造成的损耗。还试图得出 GDT 的能量平衡,以确定主要的损耗渠道,并在今后减少这些损耗。

Experimental issues of energy balance in open magnetic trap

The paper presents an overview of experimental results of an investigation of different energy loss channels in the gas dynamic trap (GDT), which is a magnetic mirror plasma confinement device in the Budker Institute of Nuclear Physics. Energy losses along magnetic field lines are considered as well as losses onto radial limiters, which restrict the plasma column radius and provide its magnetohydrodynamic stability via the ‘vortex confinement’ mechanism. The losses along the field lines were measured using a set of pyroelectric bolometers on the plasma absorber and the losses onto the limiters were determined with thermistors from their temperature rise. Additionally, the losses due to charge exchange of fast plasma ions on the residual neutral gas in the GDT were measured using a longitudinal array of pyroelectric bolometers mounted on the wall of the central cell. An attempt was made to draw up the energy balance in the GDT in order to identify the predominant loss channels and reduce those losses in the future.

期刊介绍: JPP aspires to be the intellectual home of those who think of plasma physics as a fundamental discipline. The journal focuses on publishing research on laboratory plasmas (including magnetically confined and inertial fusion plasmas), space physics and plasma astrophysics that takes advantage of the rapid ongoing progress in instrumentation and computing to advance fundamental understanding of multiscale plasma physics. The Journal welcomes submissions of analytical, numerical, observational and experimental work: both original research and tutorial- or review-style papers, as well as proposals for its Lecture Notes series.
