通道切割晶体已经过测试，可以减少双晶摇摆曲线的尾部。此类设备对于 Q 范围在 10−5 和 10−3Å−1 之间的小角度散射实验以及短时间尺度的实时实验来说是有用的工具。因此，通过该方法可以有利地研究大物体和大距离粒子间相关性。乳胶球、聚合物共混物和层状结构的测试测量显示了完美晶体小角度散射相机的能力。回转半径和层状结构的特征尺寸已确定。
Channel-cut crystals have been tested to reduce the tails of double crystal rocking curves. Such devices are useful tools for small angle scattering experiments in theQ-range between 10−5and 10−3Å−1and for real time experiments at short time scales. Therefore, large objects and large distance interparticle correlations can be investigated advantageously by this method. Test measurements with Latex sphere, polymer blends and lamellar structures have shown the capacity of perfect crystal small angle scattering cameras. The radius of gyration and the characteristic dimension of the lamellar structure have been determined.
