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

Abstract

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 wide d -spacing range and high resolution to access large unit cells, detailed structural refinements and in situ / operando measurements.
