采用成像板技术对JET-ITER类壁（ILW）计划中的钨偏滤器瓦（W涂层CFC）进行了二维氚（T）分布的死后测量。观察到的T分布明显不均匀，并且在瓦片1、3、4和6上沿环形方向延伸的具有高T浓度的带状区域。带状区域的T浓度比其他部位高一个数量级。不均匀的T分布被解释为与其他元素（如铍）的不均匀共沉积。外侧垂直瓷砖（瓷砖7和8）的T浓度较低，与其他瓷砖相比相对均匀。
Post-mortem measurements of 2-dimensional tritium (T) distribution using an imaging plate (IP) technique were performed for tungsten (W) divertor tiles (W-coated CFC) used in JET-ITER like wall (ILW) project. The observed T distributions were clearly inhomogeneous, and there were band-like regions with high T concentrations that extended in the toroidal direction on tiles 1, 3, 4 and 6. The concentrations of T in the band-like regions were higher by an order of magnitude than the concentrations in other parts. The inhomogeneous T distributions were explained by non-uniform co-deposition with other elements such as beryllium. The concentrations of T on the outboard vertical tiles (tiles 7 and 8) were low and relatively uniform in comparison with other tiles.
