FlexHCD Automounter

Beamline ID23 is part of the Macromolecular Crystallography Group which supports the study and structure determination of biological macromolecules. The beamline is composed of two independent end-stations. ID23-1 is a fully tunable beamline capable of MAD measurements from 6 to 20 keV energy (2.07 Ã… to 0.62 Ã…). The second station, ID23-2, is fixed energy (14.20 keV, 0.873 Ã…) and is dedicated to perform experiments with very small protein crystals. The optical design of ID23-2 makes use of a horizontally diffracting Si (111) monochromator and Pt coated mirrors in a Kirkpatrick-Baez (KB) geometry as the focusing system.1

Automated Systems at ID23-2:

FlexHCD is a versatile, high performance, sample changer system designed to be used in automatized synchrotron beamlines to handle biological crystallized samples at cryogenic temperatures. It allows the users to automatically transfer samples from the High Capacity Dewar to the diffractometer and back. It is based on a 6-axes robotic arm and a high capacity dewar. FlexHCD has been developed by the EMBL Diffraction Instrumentation Group in collaboration with ESRF.
