用于检测快速逃逸离子的新探针已在 W7-AS 仿星器上安装并运行。中性束注入或离子回旋加速器加热产生的快离子用于研究部分漂移优化的磁场结构的快离子约束特性以及磁流体动力学扰动引起的损耗。该探头的设计基于托卡马克聚变测试反应堆的α粒子探测器,使用闪烁体板,并允许在大范围的陀螺半径和俯仰角内同时检测同向和反向离子。
A new probe for the detection of fast escaping ions has been installed and operated at the W7-AS stellarator. Fast ions generated from neutral beam injection or ion cyclotron heating were used to study the fast ion confinement properties of the partially drift-optimized magnetic field structure as well as losses induced by magnetohydrodynamic perturbations. The design of the probe is based on the α-particle detectors of the Tokamak Fusion Test Reactor using scintillator plates and allows the detection of co-and countergoing ions simultaneously in a wide range of gyroradii and pitch angles.
