dc.description.abstractThe ECHIDNA high-resolution neutron powder diffractometer at OPAL has been in routine and largely trouble-free operation for three years. Data from ECHIDNA have appeared in over 30 publications, covering a temperature range of 1.5K to 1900K and magnetic fields up to 7 T. ECHIDNA data reduction is largely automated, with a user-friendly interface and a wide choice of output formats (hdf, pdCIF, xyd, GSAS). Data reduction implements a sophisticated approach to gain correction, described in a companion poster [1], and provides large amounts of metadata relating to the data reduction via the pdCIF output format. The range of instrument configurations continues to expand. A low-temperature (<1K), cryogen-free top-loading cryostat is currently being commissioned and first results are reported. In addition, the maximum takeoff angle has been increased from 140 to 155 degrees without compromising our ability to use the robotic sample loader. In addition to the regular calls for proposals twice a year, ECHIDNA operates a popular fast access mail-in program. In order to participate, applicants should fi ll in the simple web-based form accessed via http://neutron.ansto.gov.au. Following safety and technical review, applicants forward their samples to us and data are returned typically within one month of sample receipt. Mail-in sample environment is usually restricted to room temperature and/or 4K. © International Union of Crystallographyen_AU
