Monte Carlo and film dosimetry study of collimator effects on penumbra and out-of-field dose for very high-energy electrons

Key Points

This research aims to analyze how collimator material and geometry affect the quality of VHEE beams.
Conducted Monte Carlo simulations to evaluate collimator effects.
Compared tungsten, brass, and lead regarding beam quality and dose distribution.
Assessed collimator geometry configurations to determine optimal conditions.
Tungsten collimators provided the best attenuation for VHEE beams.
Sharpness of the beam was superior with tungsten compared to brass and lead.
Established quantitative benchmarks for VHEE collimator design.

Abstract

The presented work demonstrates that collimator material and geometry play a critical role in defining VHEE beam quality. Tungsten provided optimal attenuation and sharpness compared to brass and lead. These results establish quantitative benchmarks for VHEE collimator design and emphasize the importance of beam stability.
