# Hamiltonian bump-on-tail model: interpretation of EP/AE interaction

## TL;DR

This paper explores a Hamiltonian multi-beam approach to the bump-on-tail model, providing a new perspective on the nonlinear interaction between fast ions and Alfvén Eigenmodes in plasma physics.

## Contribution

It introduces a Hamiltonian multi-beam framework as a novel method to interpret the bump-on-tail model for plasma wave-particle interactions.

## Key findings

- Validates the Hamiltonian approach for BoT model
- Offers insights into nonlinear wave-particle dynamics
- Enhances understanding of Alfvén Eigenmode interactions

## Abstract

The Bump-on-Tail (BoT) model is often adopted to characterize the non-linear interaction between fast ions and Alfv\'en Eigenmodes. A multi-beam Hamiltonian approach to the BoT model is tested here as paradigm for the description of these phenomena.
