About this package

This package is a set of utils oriented towards multipacting analysis. In particular:

• Load parameter sweeps and PIC Position Monitor data from CST Particle Studio.
• Load results from SPARK3D.
• Post-treat electron vs time results from these tools: multipactor trend, (TODO: multipactor order).
• Post-treat CST's PIC Position Monitor:
• Distribution of emission energies.
• Distribution of impact energies.
• Distribution of impact angles.
• Visualize trajectories.

Installation

Requirements

You will need a recent version of Python (at least 3.12).

Installation

Simple installation

1. Create a dedicated Python environment, activate it.
2. Run pip install simultipac

[!NOTE] If you are completely new to Python and these instructions are unclear, check this tutorial. In particular, you will want to:

1. Install Python 3.12 or higher.
2. Learn to use Python environments, pipenv or virtualenv.
3. Install a Python IDE such as Spyder or VSCode.

Building form source

1. Navigate to the library installation folder.
2. git clone git@github.com:AdrienPlacais/Simulia_Multipactor_lib.git (or download it a zip).
3. Navigate to Simulia_Multipactor_lib
4. Create a dedicated python environment.
5. pip install -e .

Trajectory plots

Here we represented in red the collision points and in green the emission points. Electrons without a green point are seed electrons.
