We report inelastic neutron scattering measurements performed on a single crystal of the heavy fermion compound Ce0.925La0.075Ru2Si2, which is at the borderline between an antiferromagnetically ordered and a paramagnetic ground state. Intensity maps as a function of wavevector and energy (0.1 < E < 1.2 meV) were obtained at temperatures T = 0.1 and 2 K, using the time-of-flight spectrometer IRI...
A new method of measuring the electron-antineutrino angular correlation coefficient, little "a", from neutron decay-to be performed at the National Institute of Standards and Technology-will require an electron spectrometer that strongly suppresses backscattered electrons. A prototype consisting of six trapezoidal veto detectors arranged around a plastic scintillator has been tested with an ele...
A prototype of a fully digital data acquisition system based on 1 Gsps 12 bit digitizers for the TOFOR fusion neutron spectrometer at JET is assessed. The prototype system enables the use of geometry-based background discrimination techniques, which are modeled, evaluated, and compared to experimental data. The experimental results are in line wit...
Neutron scattering spectroscopy is a powerful probe to study phonon and magnon excitations in condensed matter physics. A development of neutron monochromator, which properly branches monochromatic neutrons from a white beam, is therefore one of the instrumental key issues in neutron science; especially, due to the lack of neutron beam flux. Ge and Si single crytals have been one of the typical...
