UB matrix implementation for inelastic neutron scattering experiments

The UB matrix approach has been extended to handle inelastic neutron scattering experiments with differing and . We have considered the typical goniometer employed on triple-axis and time-of-flight spectrometers. Expressions are derived to allow for calculation of the UB matrix and for converting from observables to Q-energy space. In addition, we have developed appropriate modes for calculation of angles for a specified Q-energy position.
