【 摘 要 】

In white neutron diffraction studies, the energy, intensity, and number of resolved Bragg peaks depend on detector resolution and background from physics processes. The statistics-sensitive non-linear iterative peak-clipping (SNIP) algorithm is widely used for subtracting the background under a peak. This paper reports the validation procedures and availability of the SNIP algorithm for time-of-flight (TOF) Bragg reflections observed with a TOF single-protein-crystal neutron diffractometer.
