Los Alamos constant-Q spectrometer
Abstract
A constant-Q spectrometer, which has been installed on the pulsed source of the Los Alamos Neutron Scattering Center, is described. It features a number of innovations that ease sample and analyzer alignment and a novel composite crystal analyzer which exploits the mosaic properties of plastically deformed germanium in a new way. Observations of phonon dispersion in aluminum and of incoherent scattering in ZrH2 are reported, along with background measurements.
