大型磁聚变装置中对α粒子的良好约束是建造磁聚变反应堆的前提。 α粒子损失的直接测量特别令人感兴趣。目前正在为欧洲联合环形托卡马克装置准备适当的诊断装置：闪烁体探测器和一组法拉第杯。两个系统都能够测量带电聚变产物和离子回旋共振加热尾离子。丢失的 α 粒子闪烁体探测器的设计属于本文的讨论范围。它将能够检测回转半径在 20 到 140mm（15% 分辨率）之间、俯仰角在 30° 到 86°（5% 分辨率）之间的颗粒。将使用 P56 作为闪烁材料。由通过准直器并撞击闪烁体的带电粒子引起的闪烁体发出的光将通过一组光学透镜和带有电荷耦合器件相机和光电倍增管阵列的相干图像光纤束进行检测。下面介绍目前...
Good confinement of alpha particles in a large magnetic fusion device is a precondition for building a magnetic fusion reactor. The direct measurement of alpha particle losses is of particular interest. Appropriate diagnostics are now being prepared for the Joint European Torus tokamak: a scintillator probe and a set of Faraday cups. Both systems are capable of measuring charged fusion products and ion cyclotron resonance heating tail ions. The design of the lost alpha particle scintillator probe is in the scope of this article. It will allow the detection of particles with a gyroradius between 20 and 140 mm (15% resolution) and a pitch angle between 30° and 86° (5% resolution). As scintillating material P56 will be used. The light emitted by the scintillator caused by charged particles that pass the collimator and hit the scintillator will be detected via a set of optical lenses and a coherent image fiber bundle with a charge coupled device camera and a photomultiplier array. In the following the present...
