Noise characteristics of the U. S. x-ray synchrotron sources are compared in the 0-2.5-kHz region. In general, little difference is found in the characteristic frequencies of the noise on focused and unfocused beamlines of a particular source, but the magnitude and white-noise levels differ. The National Synchrotron Light Source shows the least characteristic noise and the noise that is observed is small in magnitude (2-3 times the white-noise level).
