POW7 is designed for structural measurements on glasses and liquids. Figure 1 provides a schematic representation of POW7, and Table 1 gives the parameters for this instrument. The short incident flight path maintains the highest possible flux on sample to allow the counting statistics needed to effectively use isotope substitution in cases where the contrast is low. Emphasis is placed on using the shortest wavelengths practical to measure each Q in order to minimize inelasticity effects
