Unpack the reciprocal space sphere into a 3D cube, where the leading dimension of the cube is in the z -direction, the second dimension is the x -direction, and the third … WebThe origin of the crystal is at the center of the Ewald sphere, and the incoming X-rays are diffracted from that crystal. The origin of reciprocal space is at the point where the incoming X-ray beam would exit the Ewald sphere. If we rotate the crystal, we rotate the Bragg planes and so we rotate reciprocal space in the same direction.
