Simulation of electron transport in LAr under non-uniform electric fields for LArCADe at FNAL. Studies generated with this simulation can be found at https://github.com/zbeever/LArCADe-studies.
Basis of simulation outlined in Wojcik, M., & Tachiya, M. (2002). Electron transport and electron–ion recombination in liquid argon: Simulation based on the Cohen–Lekner theory. Chemical Physics Letters, 363(3-4), 381-388. doi:10.1016/s0009-2614(02)01177-6
Running the executable for LArCADe will walk you through the parameters to be specified before the simulation begins. The resulting data is exported to the py/simulation-runs folder. Examples of studies carried out with the produced simulations can be found at
Gas cross-section data is from the BSR database, www.lxcat.net, retrieved on June 11, 2019 and Rejoub, R., Lindsay, B. G., & Stebbings, R. F. (2002). Determination of the absolute partial and total cross sections for electron-impact ionization of the rare gases. Physical Review A, 65(4). doi:10.1103/physreva.65.042713. Liquid cross-section data comes from the Wojcik, M., & Tachiya, M. paper mentioned at the top.
You'll need Numpy, Scipy, and Matplotlib. Jupyter is required to view the preprocessing notebooks. CMake makes for an easy install.
Open the Jupyter notebooks in the preprocessing directory to generate the lookup tables for cross-sections and non-uniform electric fields. After doing so, set the necessary parameters in the Constants.h file. Then, navigate to the project directory in terminal and type
mkdir build
cd build
cmake ..
make
