Abstract

Laser Plasma Accelerator (LPA) produces very highly energetic electron (VHEE) beam that can be used for medical applications such as radiotherapy. This has the potential to improve cancer treatments at a cost-comparable to X-ray radiotherapy. In this context, we have performed a dedicated study considering realistic VHEE beam, produced by compact tens of TW LPA to validate the approach, considering various scenario. A full study of the dose deposition properties of a focused VHEE beam with a wide energy spectrum and maximum energy of 250 MeV based on Monte Carlo Geant4 simulations is reported. We consider a realistic manipulation of the electron beam parameters using a quadrupole triplet lattice, allowing to focus the beam into the phantom of 30 cm^3 which is placed further downstream of the beamline. To reduce the effects of unwanted ionizing radiation, a tungsten collimator is also placed in front of the last quadrupole to filter out lower energetic particles, reducing the entrance dose. The on-axis and transverse dose profiles that have been investigated when varying longitudinal positioning of the phantom, confirms the potential of VHEE for radiotherapy.
