The ITER bolometer diagnostic is planned to have 550 lines of sight (LOS) distributed all over the vessel. 240 channels are provided by cameras mounted in two upper ports and in one equatorial port. This paper describes the current status of the system level design of the port cameras and the solutions proposed on how to implement all required camera components while meeting a multitude of competing requirements. Sensor holders, support structures, and different apertures depending on the camera type (pinhole or collimator), cable connectors, ceramic track plates, and many mineral insulated cables have to be integrated within a restricted space envelope to guarantee functionality. The design of the internal electrical interfaces and the external mechanical mountings will be described as well. Using the example of an upper port camera with 60 LOS, the assembly of the camera components is explained and two currently discussed architecture options for the remote handling maintenance scheme in the hot cell are compared.
国际热核聚变实验堆（ITER）测热辐射计诊断系统计划在整个装置上分布550条视线（LOS）。安装在两个上部端口和一个赤道端口的摄像头提供240个通道。本文描述了端口摄像头系统级设计的现状，以及为在满足众多相互竞争的要求的同时实现所有所需摄像头组件而提出的解决方案。传感器支架、支撑结构以及根据摄像头类型（针孔或准直仪）而定的不同孔径、电缆连接器、陶瓷轨道板和许多矿物绝缘电缆必须集成在有限的空间范围内以确保功能。还将描述内部电气接口和外部机械安装的设计。以一个具有60条视线的上部端口摄像头为例，解释摄像头组件的组装，并比较目前在热室中远程操作维护方案的两种架构选项。
