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.

P373 – VLS-PGM BL5 SSRL

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.
