Использование тонких мишеней предлагает оптимальные условия для ускорения протонов до высоких энергий за счет взаимодействия лазера с веществом в рамках механизма TNSA. Двумерное моделирование частиц в ячейке (PIC) выполнено для исследования влияния толщины и состава мишеней на ускорение протонов. Показано, что энергия протонов увеличивается для мишени с низким атомным номером Z, проанализированы энергетические спектры He, C и Al. Максимальная энергия протонов достигается с гелиевой мишенью.

The use of thin targets offers optimal conditions for accelerating protons to high energies from lasermatter interaction in the framework of the TNSA (target normal sheath acceleration) mechanism. Twodimensional particle-in-cell (PIC) simulations were performed to investigate the effects of thickness and composition of targets in proton acceleration. We will demonstrate how proton energy increases with the target of a low atomic number Z by examining the energy spectra of the different materials He, C, and Al, whereby the maximum proton energy is obtained with a helium target.
