A novel approach with quadrupole magnets for precise deflection, scattering and focusing of very high energy electron beams (VHEE)

Nuclear Analysis
A novel approach involving quadrupole magnets has been proposed to deflect and disperse electrons in the irradiation fields, as well as a system for focusing beams at specific depths. This research also presents a comparison between VHEE and conventional
