Polarized-neutron spectrometer development and experiments at Brookhaven
Abstract
The development of polarized neutron spectrometers and the resurgence of interest in polarization analysis are described. Both Heusler crystals and FeGe multilayers used in conjunction with pyrolytic graphite crystals were tested as polarizing monochromators on a triple axis instrument. The goal is to first obtain polarized beams of adequate intensity and then to evaluate various instrumental innovations which effect control of spectrometer resolution by utilizing the properties of polarized beams. Magnetic excitations in amorphous ferromagnets employing the instrumentation for polarization analysis developed thus far is also discussed.
