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.

Installation
------------

### Using pip

Run:

```
pip install mbtrack2
```
To test your installation run:
```
from mbtrack2 import *
```

### Using conda

Clone the mbtrack2 repo and enter the repo:
```
git clone https://gitlab.synchrotron-soleil.fr/PA/collective-effects/mbtrack2.git
cd mbtrack2
```

To create a new conda environment for mbtrack2 run:

```
conda env create -f mbtrack2.yml
conda activate mbtrack2
```

Or to update your current conda environment to be able to run mbtrack2:

```
conda env update --file mbtrack2.yml
```

To test your installation run:
```
from mbtrack2 import *
```
