Beam stabilization at BL-17A (a) with and (b) without the feedback. Grey and black lines indicate the beam position and intensity, respectively. The beam energy was 12.4 keV. The beam position and intensity were measured using the position-sensitive ionization chamber and the standard ionization chamber, respectively. The standard deviation of the beam position and intensity during 20 min were effectively reduced from 3.6 µm to 1.3 µm and from 1.6 × 10−2 to 3.4 × 10−3, respectively.
