Simulations of proton beam characteristics for ELIMED Beamline

Popis výsledku v původním jazyce

ELIMED Beamline should demonstrate the capability of laser-based particle accelerators for medical applications, mainly for proton radiotherapy of tumours which requires a sufficient number of accelerated protons with energy about 60 MeV at least. In this contribution, we study the acceleration of protons by laser pulse with parameters accessible for ELIMED Beamline (intensity similar to 10(22) W/cm(2), pulse length similar to 30 fs). In our two-dimensional particle-in cell simulations, we observed higher energies of protons for linear than for circular polarization. Oblique incidence of the laser pulse on target does not seem to be favourable for proton acceleration at such high intensities as the accelerated protons are deflected from target normal axis and their energy and numbers are slightly decreased. The expected numbers of accelerated protons in the energy interval 60 MeV +/- 5% are calculated between 10(9) and 10(10) per laser shot with estimated proton beam divergence about 20 degrees (FWHM).
