P487 – DCM-PGM MIFO PTB

This monochromator was developed as a combination of a DCM and a multilayer PGM in order to cover the whole available tender X-ray energy range of 1.5-10 keV at the MIFO beamline of the PTB at BESSY using one monochromator system only. Change of operation mode between PGM and DCM is automated and does not require venting of the system.

P432 – VLS-PGM SXR XFEL PAL

This monochromator is an optimized version of the first monochromator installed at the SXR beamline at SLAC (see project P308). The required grazing incidence at XFEL beamlines implies a large distance between pre-mirror and grating, which explains the stadium-shaped footprint of the vacuum chamber.

P389 – VLS-PGM SIP ME2 SSRF

P423 – VLS-PGM SIX NSLS-II

This monochromator is part of the SIX beamline, dedicated to high resolution soft X-ray scattering experiments. Energy resolution and pointing stability are here of crucial importance.  The long pre-mirror integrated in this monochromator required an adapted design to achieve the requested high stability of mirror and grating pitch rotations. Special attention was payed to block zero-order and stray light by…

P392 – VLS-PGM ESM NSLS-II

The long pre-mirror integrated in this monochromator required an adapted design to achieve the requested high repeatability and stability of mirror and grating pitch rotations. Special attention was payed to block zero-order and stray light by using several water cooled masks and beam stops.

P403 – PGM_hard EMIL BESSY

This hard X-ray monochromator is part of the combined hard and soft X-ray EMIL beamlines at BESSY. The vacuum chamber accomodates not only the actual beam but also the passing soft X-ray beam. For DCM operation the hard X-ray beam passes without deflections through this monochromator. For PINK operation the hard X-ray beam either passes without deflection or is deflected…

P402 – PGM_soft EMIL BESSY

This soft X-ray monochromator is part of the combined hard and soft X-ray EMIL beamlines at BESSY. The vacuum chamber accomodates not only the actual beam but also the passing hard X-ray and pink beams of the neighbouring branch. In all EMIL systems we integrated for the first time electrodes for carbon contamination prevention of the optical surfaces. In this…

P401 – PGM RGBL BESSY

This plane grating monochromator design is adapted from that of the EMIL beamlines monochromators (see projects P402, P403).

P378 – VLS-PGM UPBL7 ESRF

This is the first monochromator built by Bestec with a liquid nitrogen cooling system, which was developed in cooperation with ESRF. At a temperature around 120 K, the expansion coefficient of silicon is close to 0. Therefore, a temperature distribution with strong variation does not lead to a significant deformation of the optical surface.

P355 – VLS-PGM Dreamline SSRF

P308 – VLS-PGM SXR LCLS SLAC

This monochromator was the first soft X-ray monochomator delivered to the world's first X-ray free-electron laser at LCLS at SLAC.
