Title: Upgrade of the Wide-Angle Neutron Diffractometer at the High-Flux Isotope Reactor

Conference ·
OSTI ID:786487

The Wide-Angle Neutron Diffractometer (WAND) installed at the High-Flux Isotope Reactor (HFIR) has been upgraded for new experiments. The main feature of this upgrade is the replacement of its detector with a newly developed curved one-dimensional 3He position-sensitive counter composed of 624 individual anodes. From the results of test-measurements of the detector performance, it is found that the intrinsic angular resolution and the maximum neutron-counting rate per anode are 0.25 degrees and 2.0 x 10 counts/second, respectively.
