Using Relativistic Self-Trapping Regime of a High-Intensity Laser Pulse for High-Energy Electron Radiotherapy

Abstract— Full-3D particle-in-cell Monte Carlo simulation of a new scheme electron radiotherapy based on acceleration by high-power femtosecond laser pulse propagating in plasma sub-critical density the relativistic self-trapping regime (V. Yu. Bychenkov et al., Plasma Phys. Control. Fusion 61 , 124004 (2019)) was carried out. Based results distribution energy deposited bunches accelerated such high-efficiency regime, it is demonstrated that facility $$ \gtrsim {\kern 1pt} 100$$ TW class capable providing therapy deep soft-tissue lesions soft biotissue and this approach has number advantages relative to traditional methods beam therapy.
