INEL4 is designed to be the workhorse instrument for inelastic studies requiring good resolution and extended ranges in both Q and E. Figure 1 provides a schematic representation of INEL4, and Table 1 provides the parameters for this instrument. This instrument is capable of studies involving energy transfers ranging from a few meV to more than 1 eV. The wide angular coverage and large solid angle of detectors provide relatively high data rates and an extensive Q range
