Abstract -------- ImagingReso is an open-source Python library that simulates the neutron resonance signal for neutron imaging measurements. By defining the sample information such as density, thickness in the neutron path, and isotopic ratios of the elemental composition of the material, this package plots the expected resonance peaks for a selected neutron energy range. Various sample types such as layers of single elements (Ag, Co, etc. in solid form), chemical compounds (UO\ :sub:`2`, Gd\ :sub:`2`\O\ :sub:`3`, etc.), or even multiple layers of both types can be plotted with this package. Major plotting features include display of the transmission/attenuation in wavelength, energy, and time scale, and show/hide elemental and isotopic contributions in the total resonance signal. The energy dependent cross-section data used in this library are from `National Nuclear Data Center `__, a published online database. `Evaluated Nuclear Data File (ENDF/B) `__ [1] is currently supported and more evaluated databases will be added in future. Python packages used are: SciPy [2], NumPy [3], Matplotlib [4], Pandas [5] and Periodictable [6]. Statement of need ----------------- Neutron imaging is a powerful tool to characterize material non-destructively. And based on the unique resonance features, it is feasible to identify elements and/or isotopes which resonance with incident neutrons. However, a dedicated tool for resonance imaging is missing, and **ImagingReso** we presented here could fill this gap. Community guidelines -------------------- **How to contribute** Clone the code to your own machine, make changes and do a pull request. We are looking forward to your contribution to this code! **How to report issues** Please use 'Issues' tab on Git to submit issue or bug. **Support** You can email authors for support. Installation instructions ------------------------- Python 3.5+ is required for installing this package. Install **ImagingReso** by typing the following command in Terminal: .. code-block:: bash $ conda config --add channels conda-forge $ conda install imagingreso or .. code-block:: bash $ python3 -m pip install ImagingReso or by typing the following command under downloaded directory in Terminal: .. code-block:: bash $ python setup.py Example usage ------------- Example of usage is presented at http://imagingreso.readthedocs.io/ . Same content can also be found in ``tutorial.ipynb`` under ``/notebooks`` in this repository. Calculation algorithm --------------------- The calculation algorithm of neutron transmission *T*\ (*E*), is base on Beer-Lambert law [7]-[9]: .. figure:: https://github.com/ornlneutronimaging/ImagingReso/blob/master/documentation/source/_static/Beer_lambert_law_1.png :alt: Beer-lambert Law 1 :align: center where N\ :sub:`i` : number of atoms per unit volume of element *i*, d\ :sub:`i` : effective thickness along the neutron path of element *i*, σ\ :sub:`ij` (E) : energy-dependent neutron total cross-section for the isotope *j* of element *i*, A\ :sub:`ij` : abundance for the isotope *j* of element *i*. For solid materials, the number of atoms per unit volume can be calculated from: .. figure:: https://github.com/ornlneutronimaging/ImagingReso/blob/master/documentation/source/_static/Beer_lambert_law_2.png :align: center :alt: Beer-lambert law 2 where N\ :sub:`A` : Avogadro’s number, C\ :sub:`i` : molar concentration of element *i*, ρ\ :sub:`i` : density of the element *i*, m\ :sub:`ij` : atomic mass values for the isotope *j* of element *i*.
