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.
