Abstract: Wombat is the high‐intensity neutron diffractometer in operation at the Australian Centre for Neutron Scattering. While Wombat is primarily used as a high‐speed powder diffractometer, the high‐performance area detector allows both texture characterization and single‐crystal measurements. The instrument can be configured over a large range of operational parameters, which are characterized in this contribution to aid experimental planning. Wombat is particularly optimized for the study of materials in situ and in operando using the wide range of sample environments available at the centre. Over 17 years of operation, Wombat has been used to explore a broad range of materials, including novel hydrogen‐storage materials, negative‐thermal‐expansion materials, cryogenic minerals, piezoelectrics, high‐performance battery anodes and cathodes, high‐strength alloys, multiferroics, superconductors, and novel magnetic materials. This paper will highlight the capacity of the instrument, recent comprehensive characterization measurements and how the instrument has been utilized by our user community to date.
