Beam line 7-2 is a wiggler end station dedicated for x-ray scattering with a focus on in-situ experiments. BL7-2 is equipped with a customized Huber type 5021 6+2 axis diffractometer and uses PILATUS 100K and 300K area detectors (including for 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. After many years of service, the scattering capability is planned to be removed from bamline 7-2 after the first cycle of 2019 (March 2020). All of the wonderful capabilities our users have appreciated will be available at the new undulator scattering beamline BL 17-2 later in 2020.
