TL;DR: In this paper, a Linac Coherent Light Source (LCLS) based on a high energy accelerator such as, eg, the 3 km S-band structure at the Stanford Linear Accelerator Center (SLAC), followed by a long high-precision undulator with superimposed quadrupole (FODO) focusing, is proposed to fulfill the given requirements for SASE operation in the 1000 A−1 A range.

TL;DR: In this article, an analysis of heat flows and thermal stresses in ultrafine transmission gratings irradiated with synchrotron light is presented, and theoretical results are presented as preliminary to future testing of power loading in ultra-fine gratings and also as guidelines to associated monochromator design.

TL;DR: In this paper, the authors used a filter-photodiode monitor, gained over several years of monitoring radiation from the SSRL/LBL undulator on the Aladdin storage ring.

TL;DR: In this paper, the authors presented the results of a variational analysis of the equation describing single electron undulator radiation, in the sense of maximizing the intensity density of the radiation in the forward direction and establishing the optimum amplitudes of the electron motion in terms of the total electron speed, βc, and the average on-axis component of electron velocity, β ∗ c.

TL;DR: In this article, the authors derived the thickness profiles of metallic planar transmission gratings in the soft X-ray range which maximize the output/input and output/output intensity ratios.
