Prismatic analyser concept for neutron spectrometers.

A Prismatic Analyser concept for Neutron Spectrometers

A development in modern neutron spectroscopy is to avoid the need of large samples. We demonstrate how small samples together with the right choice of analyser and detector components makes distance collimation an important concept in crystal analyser spectrometers. We further show that this opens new possibilities where neutrons with different energies are reflected by the same analyser but co...

Passive neutron area monitor with CR39

Background: In high-intensity, mixed and pulsed neutron fields the use of spectrometers or area monitors with active detectors is useless in these conditions neutron measuring devices must have a passive detector. Here a passive neutron area monitor with CR39 track detector was designed and the response was calculated. Materials and Methods: The response of a passive neutron area monitor with C...

8 collimations 109-209-209-209 we obtained a wavevector resolution of dQ=Q ˆ 0:0020. Inelastic neutron scattering. A 50-g powder sample was sealed with He exchange gas in a thin-walled aluminium can for the inelastic neutronscattering experiments at the NIST centre for neutron research. For energy transfers ,40 meV we used a direct geometry time-of̄ight (TOF) spectrometer in the neutron energy g...
