| contents | We introduce a computer program to simulate the results of neutron powder-diffraction experiments at the High Flux Isotope Reactor at Oak Ridge National Laboratory. The program is freely available as a web application at http://addie.ornl.gov/hfirestimate, and is designed to be straightforward to use for researchers who are new to neutron diffraction. The input includes the crystal structure of the proposed sample, the sample mass, and the instrument configuration. The results include a plot of the simulated data -- including realistic estimates of background and the error bars due to counting statistics -- and suggestions of how to resolve potential problems with the experiment. Here, we explain the design and implementation of this program and demonstrate its performance using comparisons of simulated and experimental data. We hope that this program will enable researchers to plan neutron-scattering experiments more effectively, increasing the likelihood of successful experiments and improving the productivity of neutron-diffraction research. |
