EAST偏滤器由内靶、外靶和整流罩组成。每种靶沿沿着环向有16个独立的模块。偏滤器的结构包括支架、热沉和第一壁石墨。对偏滤器的形状和尺寸进行了优化设计，使偏滤器能够灵活地运行于不同的等离子体伸长和三角形。强环向磁场作用下的涡流和晕流会对偏滤器产生很大的电磁力，偏滤器结构必须承受这些电磁力。偏滤器第一壁的装配精度要求很高，达到0.5mm。由于偏滤器位置的特殊性，传统的直接用光学仪器测量的方法是不切实际的。该基准模板与光学仪器相结合，对偏滤器进行了简单有效的对准。
The divertor of EAST is composed of inner-target, outer-target and dome. Every kind of target has 16 separate modules along toroidal direction. The structure of divertor includes support, heat sink and the first wall graphite. The shape and dimension of divertor are optimized for flexible operation of different elongation and triangularity of plasma. The eddy current and halo current interact with high toroidal magnetic field will produce large forces on divertor, so the structure of divertor must bear these electromagnetic forces. The first wall of divertor must have high assembly accuracy of 0.5mm. The traditional method using optical instruments to survey directly is impractical because of the especial location of divertor. The benchmark templet integrates with optical instruments to align the divertor is proved simple and effective.
