ResLibCal : a new tool for TAS data analysis
Lundi 28 septembre 2015 11:00

Lieu : ILL 4, Seminar Room (no 163), 71 avenue des Martyrs - Grenoble
Orateur : Emmanuel FARHI (Institut Laue-Langevin)
The ResLibCal application is a new tool to compute the resolution function of a TAS. A set of methods are available in different Cooper-Nathans and Popovici flavours. The resolution function and the spectrometer geometry can be plotted in projection and 3D, including along measurement scans.
In addition, it is possible to convolve any 4D S(q,w) dispersion model with the TAS resolution in order to simulate and fit measurements. In order to demonstrate this 4D convolution procedure, a set of S(q,w) models are proposed, including simple spin-waves, acoustic phonons in cubic monoatomic materials, perovskites, as well as two general S(q,w) calculators computing the phonon spectra from ab-initio (using Quantum-Espresso/PHON and ASE).
The use of this tool is done through a GUI with plots, and the convolution procedure is controlled using a few commands.
A short presentation will be given, followed by a demo, and a general discussion about your expectations and future developments.
ResLibCal is using parts from ResCal and ResLib, with many bug fixes, especially in the UB matrix, Monte-Carlo convolution, CN and Popovici matrices.
