Welcome to the PyHEADTAIL wiki

PyHEADTAIL is

• a python library to numerically simulate particle beam dynamics;
• based on macro-particles to model collective effects of charged beam plasmas;
• developed and maintained at CERN.

This wiki explains how to

1. set up PyHEADTAIL
2. use PyHEADTAIL
3. exploit the GPU for simulations

What is PyHEADTAIL used for?

Beam dynamics studies with PyHEADTAIL include

CERN:

• radio frequency gymnastics to create hollow longitudinal phase space distributions in the Proton Synchrotron Booster
• injection oscillations with indirect and direct space charge effects at the Proton Synchrotron
• electron cloud instability simulations along the acceleration ramp of the Super Proton Synchrotron
• radio frequency quadrupole proof-of-principle studies for enhanced Landau damping at the Large Hadron Collider
• double harmonic radio frequency systems and their impact on transverse impedance related instabilities for the High Luminosity Large Hadron Collider

PSI:

• microwave instability simulations for the Swiss Light Source

The collective effects course at the US Particle Accelerator School 2015 has been taught using PyHEADTAIL.
