Filter banks can be used to investigate the contributions of harmonics to the beam on sample or in various multiple-sample approaches. A challenge is to make these measurements fast, efficient and automated, whether for beamline characterization or diagnosis, or for the accurate measurement of X-ray absorption spectroscopy (XAS) in either transmission or fluorescence. Similarly, complex angular-dependent measurements can quantify elastic and inelastic scattering and fluorescence. A challenge is to quantify these within experiment as a fast, efficient diagnostic and for the measurement of key systematic errors to extract attenuation coefficients, absorption coefficients or the XAS structure near an edge. The current implementations of daisy wheels provide a fast and efficient diagnostic.
