BL10-2a

Overview
BL10-2a

33-pole, 1.27-Tesla wiggler, 1.5 mrad Acceptance End-Station

Beam line currently closed for upgrade.

Beam line 10-2 is a wiggler-based source that splits time between the front hutch (BL10-2a), instrumented for wide-angle X-ray scattering, and the rear hutch (BL10-2b), instrumented for X-ray spectroscopy with a focus on in-situ, time-resolved catalyst characterization.

The BL10-2a station is equipped with a two-circle diffractometer and several area and point detectors. The end station is very flexible and can support large custom-made sample chambers such as annealers, coaters, electrochemistry and additive manufacturing chambers for in-situ diffraction experiments.

Sample Environment —
