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.

P490 – MIRROR UNIT M3M4 MIFO PTB

The hexapod units for the MIFO beamline of the PTB at BESSY feature the lastest updates of the hexapod design for compact size, straightforward alignment, and calibration at reliably excellent performance.

P490 – MIRROR UNIT M2 MIFO PTB

The hexapod units for the MIFO beamline of the PTB at BESSY feature the lastest updates of the hexapod design for compact size, straightforward alignment, and calibration at reliably excellent performance.

P490 – MIRROR UNIT M1 MIFO PTB

The hexapod units for the MIFO beamline of the PTB at BESSY feature the lastest updates of the hexapod design for compact size, straightforward alignment, and calibration at reliably excellent performance.

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.
