Figure 2
Square-root power spectral density (top) and square root of the integrated power spectral density (bottom) of baseline X-ray beam motion (without feedback) at the focusing point, measured by (a) XBPM-C (10 kHz sampling) and (b) the camera (100 frames s^⁻¹). Each curve represents the mean of ten acquisitions, with shaded bands indicating ±1σ (standard deviation).
