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).

P409 – Mirror Unit CAT_soft EMIL BESSY

This soft X-ray deflecting mirror unit is part of the combined hard and soft X-ray EMIL beamlines at BESSY. It features an optimized design of the constant-strut-length hexapod mechanism used for the first Bestec hexapod (see project P377). The vacuum chamber accomodates not only the actual beam but also the passing hard X-ray beam of the neighbouring branch.

P408 – Mirror Unit SISSY_soft EMIL BESSY

This soft X-ray split mirror unit is part of the combined hard and soft X-ray EMIL beamlines at BESSY. It features an optimized design of the constant-strut-length hexapod mechanism used for the first Bestec hexapod (see project P377). The mirror splitting is realized by a vertical movement. The vacuum chamber accomodates not only the actual beam but also the passing…

P418 – Exit Slit Unit RGBL BESSY

This exit slit unit design is adapted from that of the EMIL beamlines exit slit units (see projects P414 to P417).

P415 – Exit Slit Unit CAT_soft EMIL BESSY

This soft X-ray exit slit unit is part of the combined hard and soft X-ray EMIL beamlines at BESSY.

P414 – Exit Slit Unit SISSY_soft EMIL BESSY

This soft X-ray exit slit unit 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 beam of the neighbouring branch.

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.

P383 – Exit Slit Unit B24 DLS

This exit slit unit is the first featuring a modified design of the slit blade mechanics for improved alignment stability.  A custumized wedge leveler was used for a more convenient and reliable height adjustment of the slit unit.

P377 – Mirror Unit PM2 BESSY

For this collimating mirror unit we developed the constant-strut-length hexapod mechanism, which allows for a motorized movement in six degrees of freedom. Exceptionally large ranges can be covered with very high speed and positioning repeatability. The large rotational roll range travelled in a few seconds enables polarization switching e.g. for XMCD experiments.
