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