متن کاملLaser-accelerated protons with energy-dependent beam direction.
The spatial distribution of protons, accelerated by intense femtosecond laser pulses interacting with thin target foils under oblique irradiation are investigated. Under certain conditions, the proton beams are directed away from the target normal. This deviation is towards the laser forward direction, with an angle that increases with the level and duration of the amplified spontaneous emissio...
متن کاملEnergy optimization procedure for treatment planning with laser-accelerated protons.
A simple analytical model is found that predicts the exact proton spectrum needed to obtain a spread-out-Bragg peak (SOBP) distribution for laser-accelerated proton beams. The theory is based on the solution to the Boltzmann kinetic equation for the proton distribution function. The resulting analytical expression allows one to calculate the SOBP proton energy spectra for the different beamlet ...
متن کامل3D-flow modeling of laser-accelerated protons and electric field reconstruction
The irradiation of foil targets with ultra-intense short laser pulses leads to the generation of MeV ion beams from the non-irradiated target rear side [1]. The ions, mostly protons originating from contaminants, form a collimated beam with an exponential energy spectrum falling to high energies and a sharp cut-off at up to 60 MeV, depending on the laser parameters. With special target cleaning...
متن کاملBroad energy spectrum of laser-accelerated protons for spallation-related physics.
A beam of MeV protons, accelerated by ultraintense laser-pulse interactions with a thin target foil, is used to investigate nuclear reactions of interest for spallation physics. The laser-generated proton beam is shown (protons were measured) to have a broad energy distribution, which closely resembles the expected energy spectrum of evaporative protons (below 50 MeV) produced in GeV-proton-ind...
