JANUS

A computational framework for studying high-energy particle transport and production.

Overview

Janus couples Geant4 particle-interaction simulation with Xsuite beam transport to study how physical parameters affect downstream particle behavior.

The case study explored 26 GeV proton bombardment of a high-Z target, with antiproton production as the primary observable.

PHYSICAL MODEL
Particle interaction: Geant4 models high-energy proton–target interactions and particle production.
Beam transport: Xsuite models relativistic particle transport through accelerator lattices and magnetic elements.

Research Question

“How do physical beamline parameters influence coupled high-energy particle simulations?”

The exploration focused on parameter sensitivity, downstream beam behavior, and the computational structure of coupling particle-interaction and beam-transport simulations.

Implementation

The implemented system includes:

  • Geant4 target bombardment and collision validation
  • ROOT-based particle data transfer
  • Xsuite beam transport
  • Configurable drift, quadrupole, bend, and aperture elements
  • Transport diagnostics and validation tests
