(a) The $\mathrm{\Delta }\theta$ scan at $\mathrm{\Delta }\phi =\mathrm{\hspace{0.17em}\hspace{0.17em}}0$ and (b) the $\mathrm{\Delta }\phi$ scan at $\mathrm{\Delta }\theta =\mathrm{\hspace{0.17em}\hspace{0.17em}}0$ of the transmitted beam through the crystal device No. 1. (c) and (d) The beam sizes of the transmitted beams through the crystal devices, No. 1 and No. 2, with (black dots) and without the back diffraction (gray dots) versus the distance from the exit end of the crystal devices.
