窗户主要使用聚酯薄膜和/或 5 µm 厚的聚碳酸酯箔。箔片还起到样品背衬的作用，以最小化窗口和样品之间的距离。每个样品架上附有一个窗口，该窗口是由丙烯酸树脂制成的环形盘；大气侧锥孔的直径为1.2mm。样品放置在支架上；旋转台上最多可安装六个支架。提取的质子束的最终分辨率可以保持在 1 µm。 2, 5
Mylar and/or 5 µm-thick polycarbonate foils were mainly used for the window. The foils also play the role of sample backing to minimize the distance between the window and the samples. A window is attached on each sample holder, which is an annular disk made by acrylic resin; the tapered hole has a 1.2 mm diameter on the atmospheric side. Samples are set on holders; up to six holders can be mounted on the revolving stage. The final resolution of the extracted proton beam can be kept at 1 µm. 2, 5
