TxPhysics Library
Advanced Physics For Accelerator Simulations
The TxPhysics library from Tech-X Corporation is a cross-platform library of computational modules for modeling how charged particles interact with their environment. The TxPhysics library includes models for impact ionization of neutral gases by electrons and ions, field-induced tunneling ionization of atoms, ion range and stopping power in solids, ion-induced electron yield from solids, and secondary electron yields.
These effects are important in low-pressure discharges for ion sources, waveguide breakdown for microwave physics, and plasma creation during laser-plasma interaction. Tech-X researchers and their collaborators have published discussions on many of the algorithms in the TxPhysics library, including:

TxPhysics Library Model in Use: The image below is from an OOPIC Pro simulation showing argon ion density in a closed-drift ion source. Two important mechanisms for generating and maintaining this discharge are impact ionization and ion-induced electron yield. Models for these two mechanisms and more are included in the TxPhysics library.
