光学等离子体诊断系统通常需要涉及镜子、透镜和窗口的复杂光路。光纤的使用可以显着简化此类系统的设计。辐射引起的效应，即引起的吸收和发光，可能会损害诊断系统中光纤的集成。然而，新型熔融石英玻璃类型的最新发展为使用光纤作为波导装置开辟了前景。在本文中，我们介绍了欧洲、日本和俄罗斯在建立标准化循环程序以在相关 ITER 条件下测试光纤方面所做的共同努力。循环程序应允许选择最合适的光纤。我们用比利时核能研究中心 BR2 材料测试反应堆中纯石英光纤的堆内反应堆辐照结果来简要说明讨论。
Optical plasma diagnostic systems often require a complex optical path involving mirrors, lenses and windows. The use of optical fibres could significantly simplify the design of such a system. Radiation-induced effects, namely induced absorption and luminescence, may compromise the integration of optical fibres in the diagnostic system. However, recent developments of new fused silica glass types open perspectives to use optical fibres as a wave-guide device. In this paper, we present the common European, Japanese and Russian efforts in setting up a standardized round-robin procedure to test the optical fibres under relevant ITER conditions. The round-robin procedure should allow to select the most appropriate optical fibre. We briefly illustrate the discussion with results of an in-core reactor irradiation of pure silica optical fibres in the BR2 material testing reactor of the Belgian Nuclear Energy Research Centre.
