A double-crystal diamond (111) monochromator recently implemented at the Linac Coherent Light Source (LCLS) enables splitting of the primary X-ray beam into a pink (transmitted) and a monochromatic (reflected) branch. The first monochromator crystal, with a thickness of ∼100 µm, provides sufficient X-ray transmittance to enable simultaneous operation of two beamlines. This article reports the d...

The Center for Advanced Microstructures and Devices’(CAMD) aging plane-grating soft x-ray monochromator beamline was upgraded to a varied-line-space plane-grating monochromator (VLSPGM) beamline. Preliminary measurements indicate significant performance improvements in both the resolving power and the throughput over its predecessor. However, it was found that the VLSPGM has less than the calcu...

Trochoidal electron monochromator (TEM) which uses crossed homogeneous electric and magnetic fields has been investigated in a numerical simulation using the SIMION 8.0 package. The electron trajectory calculations have been carried out for large number of initial electrons with finite energy spread and angular distribution function. The electron energy distribution function (EEDF) of the TEM h...

The SAMBA X-ray Absorption beamline has been operating for users since January 2008. The beamline covers a large energy range from 4 up to 40 keV in two working modes: a “high flux” mode using a sagittally focusing monochromator and a “time-resolved” mode using a dedicated Quick-EXAFS monochromator. Herein a technical description of the main beamline components is given and results concerning e...
