Life Sciences
Sector 21 is a canted undulator beamline with the upstream undulator providing tunable X-rays via a Kohzu double crystal monochromator. Bimorph mirrors focus the beam and keep it centered on the sample. The end station has an MD3-UP microdiffractometer with an adjustable kappa goniometer, UR robotic sample changer, cryostat, and Arinax HC-Lab Humidity Controller. Historically the station has predominately performed high throughput cryocrystallography, but more of the time will be focused on serial and pump-probe crystallography going forward.
