neutronbraggedge

A Python library for neutron Bragg edge analysis used in neutron imaging research at Oak Ridge National Laboratory.

Overview

Bragg edges occur at specific wavelengths in neutron transmission spectra due to crystallographic diffraction. This library calculates:

• Bragg edge positions for various materials
• d-spacings from crystal structure
• Lattice parameters from experimental data
• Wavelength/TOF conversions

Installation

pip install neutronbraggedge

Quick Start

from neutronbraggedge.braggedge import BraggEdge

# Get Bragg edges for Iron
handler = BraggEdge(material='Fe', number_of_bragg_edges=4)
print(handler.bragg_edges['Fe'])
# [4.0537, 2.8664, 2.3404, 2.0269]

print(handler.metadata['crystal_structure']['Fe'])
# 'BCC'
