Title: | Simulating the optical performances of the LCLS bendable mirrors using a 2D physical optics approach | Authors: | SPIGA, Daniele Cocco, D. Hardin, C. L. Morton, D. S. Ng, M. L. |
Issue Date: | 2018 | Volume: | Adaptive X-Ray Optics V | Editors: | Spiga, Daniele; Mimura, Hidekazu | Series: | PROCEEDINGS OF SPIE | Number: | 10761 | First Page: | 1076107 | Abstract: | The Linac Coherent Light Source (LCLS), a US Department of Energy Office of Science X-ray facility operated by the Stanford University, is being upgraded with a second source to provide eight beamlines (five existing and three under construction) with either high-repetition or high-intensity pulses and highly coherent X-ray beams. The photon transportation and distribution to each beamline relies on, among other elements, elliptically- bendable mirrors, often in Kirkpatrick-Baez (K-B) configuration. One of the crucial tasks in beamline design and performance prediction is the self-consistent simulation of the final point spread function of the complete optical system, simultaneously accounting for diffractive effects, mirror deformations, and surface finishing defects. Rather than using ray-tracing routines, which cannot manage diffractive effects, and rather than employing the first-order scattering theory, which cannot be applied when the optical path differences exceed the radiation wavelength, a wavefront propagation formalism can be used to treat all the aspects at the same time. For example, the WISE code, initially developed for astronomical X-ray mirrors at INAF-OAB, and subsequently used to simulate X-ray reflective systems at the Fermi light source, is now a part of the well-known OASYS simulation package. In this paper, we extend the model to a two-dimensional imaging and show performance simulations of two elliptical mirrors to form a complete Kirkpatrick-Baez system | Conference Name: | Adaptive X-Ray Optics V | Conference Place: | San Diego, California | Conference Date: | 19-23 August, 2018 | URI: | http://hdl.handle.net/20.500.12386/27760 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/10761/2323253/Simulating-the-optical-performances-of-the-LCLS-bendable-mirrors-using/10.1117/12.2323253.short?SSO=1 | ISSN: | 0277-786X | ISBN: | 9781510620933 | DOI: | 10.1117/12.2323253 | Bibcode ADS: | 2018SPIE10761E..07S | Fulltext: | open |
