Experimental Station 7-2

Beamline 7-2 is a wiggler beamline dedicated for X-ray scattering and time-resolved experiments (>0.005 s). 7-2 is equipped with a customized Huber type 5021 6+2 axis diffractometer and uses PILATUS 100k and 300k area detectors (including time-resolved experiments), a Si crystal-analyzer  with point detector for high resolution studies, or a 1 mradian Soller slit with a Vortex Si drift detector.
