MATXCOM—an x-ray/gamma-ray attenuation calculator for arbitrary materials

Note

MATXCOM can now be used directly from web browser: Launch Web App. This is the most user-friendly and recommended way to use MATXCOM (same backend as the command-line version).

Note

  • MATXCOM v1.1 is the latest release and includes important feature upgrades for improved usability and flexibility. It is intended for testing and feedback.

  • The current releases are Windows-only. For a Linux binary or the source code, please contact the author.

  • Please report any issues or suggestions via the Issues section.

MATXCOM is a specialized program developed for the calculation of x-ray and gamma-ray interaction cross-sections and attenuation parameters for arbitrary materials. Based on the EPICS2023 evaluated photon data library (EPDL), MATXCOM calculates the following properties:

  • Mass attenuation coefficient (MAC)

  • Linear attenuation coefficient (LAC)

  • Half and tenth value layers (HVL and TVL)

  • Mean free path (MFP)

  • Total atomic and electronic cross-sections (ACS and ECS)

  • Effective atomic number (Zeff)

  • Effective electron density (Neff)

  • Effective conductivity (Ceff)

  • Energy absorption and exposure buildup factors (EABF and EBF)

Note

The latest release also includes support for the XCOM/NIST Standard Reference Database 8 (XGAM) data library as an alternative to EPICS2023/EPDL.

This guide provides instructions on how to install, run, and use MATXCOM v1.1. It also includes examples to help you get started.
