Finite-element analysis is used to study the thermal deformation of a multilayer mirror due heat load from undulator beam at low-emittance synchrotron source, specifically ESRF-EBS upgrade beamline EBSL-2. The energy bandwidth double-multilayer monochromator larger than that relevant harmonic, such considerable portion reflected. Consequently, absorbed power non-uniformly distributed on surface...

The performance of a liquid-nitrogen-cooled high-heat-load monochromator with horizontal scattering plane has been analysed, aiming to preserve the high quality X-ray beam in vertical for downstream optics. Using finite-element analysis, height profiles crystal surface various heat loads and corresponding slope errors meridional sagittal planes were calculated. Then angular distortions reflecte...

The stability of the photon beam position on synchrotron beamlines is critical for most if not all synchrotron radiation experiments. The position of the beam at the experiment or optical element location is set by the position and angle of the electron beam source as it traverses the magnetic field of the bend-magnet or insertion device. Thus an ideal photon beam monitor would be able to simul...

The crystal monochromator beamline KMC-1 at a BESSY II bending magnet covers the energy range from soft (1.7 keV) to hard x-rays (12 keV) employing the (n,-n) double crystal arrangement with constant beam offset. The monochromator is equipped with three sets of crystals, InSb, Si (111), and Si (422) which are exchangeable in situ within a few minutes. Beamline and monochromator have been optimi...
