The Liquids Reflectometer at SNS

Liquids Reflectometer

The reflectometry beam line at SNS consists of two separate instruments sharing the same primary shutter, one specialized in soft matter/liquids experiments and the other in magnetism (see Magnetism Reflectometer).

The Liquids Reflectometer is designed for viewing horizontal surfaces and is used for a wide range of science. Data rates and Q-range covered at a single scattering angle setting are sufficiently high to permit "real-time" kinetic specular reflectivity on many systems. Time-resolved phenomena such as chemical kinetics, solid-state reactions, phase transitions, and chemical reactions in general are accessible for study.
