A real time Wall Monitoring System (WMS) is used on the WEST tokamak during the C4 experimental campaign. The WMS uses the wall surface temperatures from 6 fields of view of the Infrared viewing system. It extracts the raw digital data from selected areas, converts it to temperatures using the calibration and write it on the shared memory network being used by the Plasma Control System (PCS). The PCS feeds back to actuators, namely the injected power from 5 antennae's of the lower hybrid and ion cyclotron resonance radiofrequency (RF) heating systems. WMS activates feed back control 63 times during C4, which is 14 % of the plasma discharges. It activates mainly as the result of a direct RF loss to the upper divertor pipes. The feedback control maintains the wall temperature within the operation envelope during 97 % of the occurrences, while enabling plasma discharge continuation. The false positive rate establishes at 0.2 %. WMS significantly facilitated the operation path to high power operation during C4, by managing the technical risks to critical wall components.

在C4实验活动期间，WEST托卡马克上使用了实时墙监控系统（WMS）。WMS使用红外观察系统的6个视场中的壁表面温度。它从选定的区域提取原始数字数据，使用校准将其转换为温度，并将其写入等离子控制系统（PCS）使用的共享存储网络中。PCS反馈到执行器，即从下部混合动力和离子回旋共振射频（RF）加热系统的5个天线注入的功率。WMS在C4期间激活63次反馈控制，这是等离子放电的14％。它的激活主要是由于射频直接损失到上分流器管道。反馈控制可在97％的事件发生期间将壁温保持在操作范围内，同时使等离子体放电得以继续。假阳性率确定为0.2％。通过管理关键墙组件的技术风险，WMS大大简化了C4期间大功率运行的操作路径。
