Doses for X-ray and electron diffraction: New features in RADDOSE-3D including intensity decay models

Area of Science:

• Materials Science
• Computational Physics
• Radiation Dosimetry

Background:

• Accurate radiation dose estimation is crucial in electron microscopy and diffraction.
• Existing tools may not fully account for specific experimental conditions like diffraction intensity decay.
• Standard dose units (e.g., Gray) differ from those used in electron diffraction (e.g., electrons/Ų).

Purpose of the Study:

• To introduce new features and improvements in the RADDOSE-3D dose estimation software.
• To enhance the accuracy of dose calculations by incorporating diffraction intensity decay.
• To extend the program's utility to electron diffraction experiments and improve user accessibility.

Main Methods:

• Implementation of a diffraction intensity decay model to modify dose calculations.
• Development of RADDOSE-ED for electron diffraction, adapting dose units.
• Creation of a graphical user interface (GUI) for RADDOSE-3D.

Main Results:

• The program can now calculate a "Diffraction-Decay Weighted Dose" by incorporating intensity decay.
• RADDOSE-ED provides dose estimation in electrons/Ų for electron diffraction.
• The new GUI simplifies access to RADDOSE-3D's advanced features.

Conclusions:

• RADDOSE-3D has been significantly updated to offer more precise and versatile radiation dose estimation.
• The inclusion of electron diffraction capabilities and a user-friendly GUI broadens its applicability.
• These advancements improve the reliability of dose measurements in various electron beam experiments.
