A two-day meeting was held at Argonne on April 16–17, 1990 to celebrate the inauguration of GLAD, a new diffractometer dedicated to measuring the structures of glasses and liquids. It has just come into operation at Argonne's Intense Pulsed Neutron Source (IPNS). The instrument is the first neutron diffractometer optimized for such measurments and takes advantage of the copious supply of short-wavelength neutrons available at a pulsed spallation source such as IPNS. The use of wavelengths as low as 0.1 Å will make it possible to obtain complete diffraction patterns at low scattering angles, and avoid the systematic errors due to absorption and inelasticity effects which have plagued many measurements this kind made upt to now on conventional instruments. Data can be collected simultaneously over a wide range of scattering vector Q, overlapping with the small-angle region at low (0.05 Å−1) and extending out to Q values as high as 50 Å−1, corresponding to very high spatial resolution in the radial distribution functions. A wide range sample environments will be available, including low temperature (10 K), high temperature (1500 K) and, eventually, high pressure.
