(a) Frame-to-frame variation in the normalized integrated intensity of the 220 reflection of Si powder at rotation speeds of 3 and 600 r min−1. The horizontal axis represents the frame number, with an exposure time of 10 ms per frame. (b) Relative fluctuation of the integrated intensities (σ/〈I〉) for the 220 and 311 reflections as a function of rotation speed. The fluctuation decreases with increasing rotation speed and reaches <1% above ∼200 r min−1, indicating improved intensity uniformity.
