SimCC is a Python package for simulating charge-state changes in materials.

You can try this package at https://simcc-web.streamlit.app/ .

Required:

• pycatima
• numpy
• scipy

Optional:

• jupyter
• streamlit
• matplotlib
• plotly

• Calculate charge-changing cross-sections and mean free paths
• Simulate charge-state changes in materials using the Monte Carlo method
• Calculate energy loss in materials

Follow these steps to install SimCC:

1. Create and activate a virtual environment:

   sudo apt update
   sudo apt install python3-venv python3-dev
   cd ~/venv
   python3 -m venv venv
   source venv/bin/activate  # On macOS/Linux
   venv\Scripts\activate  # On Windows

2. Install build-essential and cmake:

   sudo apt install build-essential cmake

3. Clone the repository:

   cd ~
   git clone https://github.com/yoshimotomasahir/simcc.git

4. Navigate to the project directory:

   cd simcc

5. Install using pip:

   pip install .

Example files for Jupyter and Streamlit are available in the examples directory.

To run Streamlit, execute the following commands:

streamlit run ./examples/app.py

Note that this simulation does not consider transitions of two-electrons capture and two-electrons removal.

Note that the cross sections does not match perfectly with the GLOBAL ones, see the cross section data.
