NASA-gamma

Gamma spectrocopy tools and visualizations. Some of its capabilitis include:

1. Spectrum smoothing, rebinning, plotting
2. Peak searching given detector resolution and minimum SNR
3. Spectrum decomposition into signal, noise, and background
4. Peak fitting of multiple overlapping peaks with different background functions
5. Extraction of Gaussian components of peaks
6. Fully functional GUI
7. Energy calibration
8. Efficiency calibration
9. FWHM vs. energy plots
10. Time analysis from LYNX data
11. Data visualization for PIXIE data in the context of Associated Particle Imaging (API)
12. Gamma energy identification with built-in databases. Emphasis is placed on neutron induced gamma ray emission.

Installation

nasagamma runs on Python 3.6 or higher version. You can install it by downloading the package directly using

git clone https://github.com/mauricioAyllon/NASA-gamma

and then run

pip install -e .

from the directory where the setup.py file is located.

Using nasagamma

Try running the following (if the path is set correctly, the GUI can run from any directory. Otherwise, run from inside the "NASA-gamma" folder):

python gammaGUI-qt -o

If running through the Spyder IDE, replace the keyword "Python" for "run". The GUI window should appear. Then select File -> open -> examples -> data -> gui_test_data_labr.csv. Click on "Find peaks", select LaBr/CeBr and hit apply. You should see several lines identified in the spectrum. Drag the mouse over one or more lines and feel free to play around. Info buttons are placed strategically to guide the user.

Development

Code contributions are welcome!

We use pre-commit to format the code with black. To enable pre-commit, you need to install it using:

pip install pre-commit

and then run

pre-commit install

inside the git repository.
