A Monte Carlo Simulation of Neutron Instrument Resolution Functions
(2013) In Journal of the Physical Society of Japan 82. p.037-037- Abstract
- In this paper we demonstrate that the Monte Carlo simulation package McStas is a useful tool, not only for instrument design, but also for resolution function calculation. It has been possible to determine analytically the 4 dimensional resolution function of both a direct geometry time of flight neutron spectrometer and a triple axis spectrometer. The obtained resolution functions are directly comparable to and in agreement with the Monte Carlo simulated results. These results are a step towards incorporating a 4 dimensional resolution function into data analysis. For each instrument we show an example of the resolution function calculated at a particluar point in (Q, omega) space.
