The displacement and the radius of curvature as a function of crystal surface position for stepping-motor pulses of (a) 3000, (b) 2000 and (c) 500 of the bender. The displacements are estimated from the measurements of the energy shift with a narrow slit. Open circles are measured points and the dashed line for is a fit curve. The solid line is a fit curve for R. The beam footprint is ∼50 mm on the crystal. |
