Stopping-Power and Range Tables for Electrons, Protons, and Helium Ions

SRD 124 provides calculated stopping-power and range tables for charged particles in materials. The National Institute of Standards and Technology maintains these databases, which can generate tables for electrons in any user-specified material and for protons and helium ions in 74 materials. It was last updated in July 2022.

Use Cases

• Calculate projected ranges for protons and helium ions across 74 material types.
• Model electronic stopping powers for electrons in custom material compositions.
• Analyze energy loss for alpha particles using nuclear stopping power data.
• Compare stopping-power values for charged particles like electrons and protons at specified energies.

Strengths

• Calculations cover 74 specific materials for protons and helium ions.
• Maintained by the authoritative National Institute of Standards and Technology.
• Includes data for multiple particle types: electrons, protons, and helium ions.

Limitations

• Data is provided in HTML format, which is not ideal for direct programmatic analysis.
• The underlying calculation methods and raw numerical tables are not directly visible in the provided format.
• No sample data or explicit column schema is available to assess structure.
