mbtrack2

mbtrack2 is a coherent object-oriented framework written in python to work on collective effects in synchrotrons.

mbtrack2 is composed of different modules allowing to easily write scripts for single bunch or multi-bunch tracking using MPI parallelization in a transparent way. The base of the tracking model of mbtrack2 is inspired by mbtrack, a C multi-bunch tracking code initially developed at SOLEIL.

Examples

Jupyter notebooks demonstrating mbtrack2 features are available in the example folder and can be opened online using google colab:

• mbtrack2 base features
• dealing with RF cavities and longitudinal beam dynamics
• collective effects
• bunch by bunch feedback
• RF loops and feedbacks
