Title: POWGEN: rebuild of a third-generation powder diffractometer at the Spallation Neutron Source

Journal Article · · Journal of Applied Crystallography (Online)

The neutron powder diffractometer POWGEN at the Spallation Neutron Source has recently (2017–2018) undergone an upgrade which resulted in an increased detector complement along with a full overhaul of the structural design of the instrument. The current instrument has a solid angular coverage of 1.2 steradians and maintains the original third-generation concept, providing a single-histogram data set over a wided-spacing range and high resolution to access large unit cells, detailed structural refinements and in situ/operando measurements.
