We investigate use of an APPLE-type undulator for generating Laguerre-Gaussian (LG) and Hermite-Gaussian (HG) mode beams. We find that the second harmonic radiation in the circular mode corresponds to an LG beam with l=1, and the second harmonic in the linear mode corresponds to an HG beam with l=1. The combination of an APPLE undulator and conventional monochromator optics may provide an opportunity...
We discuss the role of coherence in X-ray imaging and consider how phase-space tomography can be used to extract information about partial coherence. The application of phase-space tomography to X-ray imaging will also be discussed.
