联合欧洲环面的成像诊断在等离子体壁相互作用和等离子体面组分保护的研究中已成为必不可少的。在氘操作期间，这些诊断的位置离容器很近。然而，对于50-50的氘-氚操作，中子产额对这些成像诊断电子设备的影响将导致它们在这些位置完全失效。保护这些系统不受中子的影响是通过将选定数量的这些成像系统重新安置到环面大厅外（即生物屏蔽墙的另一边）来实现的。重新安置包括建造两条穿过生物屏蔽墙的新视线，每条视线都使用延伸到机器中单独端口的光学继电器。本文首先简要介绍了两种新的观看系统。然而，它侧重于其中一个的光学建模和工程设计，这是一个多摄像头系统，产生船舶内部的广角视图（WAV）。这种WAV系统在最近的DT战役中得到了成功的应用。它工作在从可见光到中红外的宽带波长范围内。它还采用了一种新颖的内部水平运动镜子支架，由玻璃增强塑料制成，作为光学继电器的一部分。还对WAV系统的运行稳定性进行了评估，并实施了一些后期设计改进。
Imaging diagnostics in Joint European Torus have become essential in the study of plasma wall interactions and the protection of the plasma facing components. During deuterium operations, the location of these diagnostics was at close proximity to the vessel. However, for the 50–50 deuterium-tritium operation, the neutron yield impact onto the electronics of these imaging diagnostics would have caused them to fail completely at these locations. Shielding these systems from neutrons is achieved by relocating a selected number of these imaging systems to outside the Torus Hall (ie to the other side of the biological shield wall). The relocation encompasses the construction of two new lines of sight crossing through the biological shield wall and each of them using an optical relay which extends to separate ports in the machine. This article starts with a brief description of two new viewing systems. However, it focuses on the optical modelling and engineering design of one of them which is a multiple camera system producing a wide angle view (WAV) of the inside of the vessel. This WAV system has been used successfully during the recent DT campaign. It operates in a broadband wavelength range extending from the visible to the middle infrared. It also incorporates a novel in-house horizontal kinematic mirror mount made from glass reinforced plastic as part of the optical relay. The operational stability of the WAV system has also been assessed and some post design improvements implemented.
