GLAD is a time-of-flight diffractometer optimised for
structural measurements on glasses and liquids. More than 200
3He linear position-sensitive detectors spanning a nearly
continuous range of 2q from low to high angles ensure good
statistics yet still acceptable Q resolution.
Experimental programs include structural measurements on
amorphous ice, geological and high pressure glasses, superacids,
optical materials, oxide and non-oxide glasses, hydrogenous
liquids and polymers.
