travelpy 0.1.1

Python wrapper for TRAVEL particle tracking simulations

travelpy

Python wrapper for TRAVEL particle tracking simulations.

Overview

travelpy provides a modern Python interface to the TRAVEL particle tracking code, making it easier to:

• Run TRAVEL simulations from Python scripts or Jupyter notebooks
• Analyze beam and beamline files programmatically
• Process simulation outputs and visualize results
• Automate parameter sweeps and optimization studies

Quick Start

import travelpy as tp

# Configure TRAVEL path (one-time setup, if needed)
tp.set_travel_directory("C:/Program Files (x86)/Path Manager/Travel")

# Run a simulation
result = tp.run_travel("beam.dat", "beamline.in")

# Display output files
result.display_output_files()

# Access simulation data with simple properties
avgout = result.avgout
rmsout = result.rmsout

# Analyze key results
print(f"Final transmission: {avgout.transmission.iloc[-1]:.1f}%")
print(f"Final beam energy: {avgout.ekin_avg.iloc[-1]*1000:.1f} MeV")
print(f"Horizontal emittance: {rmsout.emitt_norm_rms_x_xp.iloc[-1]*1e6:.2f} mm·mrad")

# Clean up output files when done
result.clean_outputs()

Installation

pip install travelpy

Requirements

• Python 3.10+
• TRAVEL simulation code (Windows only)
• NumPy, matplotlib
