1. Inelastic Neutron Scattering

   Linked via "dispersion surfaces"

   Time-of-Flight (TOF) Spectrometers
   TOF spectrometers measure the time taken for neutrons to travel from the sample to a bank of detectors after being scattered. Incident energy resolution is often achieved using mechanical choppers that create sharp pulses of neutrons with a defined energy spread. This technique allows for simultaneous measurement across a wide range of momentum transfers $\mathbf{Q}$ for a given energy transfer $\omega$, making it superior for mapping entire [dispersion surfaces](/entries/d…
