J-PARC MLFにおける中性子散乱実験シミュレーションのためのWebアプリケーションの開発

抄録

  Neutron scattering is one of the most powerful technique to probe structures and dynamics of matters in the momentum-energy (Q-E) space. However, it is not straightforward to calculate accessible Q-E regions from the specs of each instrument, in particular in the case of time-of-flight neutron scattering instruments with a pulsed neutron source. We have thus developed JavaScript-based web applications for the HRC instrument in BL12 of the Materials and Life science experimental Facility in J-PARC. These applications enable us to simulate neutron Laue diffraction patterns, relationships between resolution and flux, and accessible Q-E range for inelastic scattering experiments, which will improve usability of the HRC instrument.
