First theoretical determination of relative biological effectiveness of very high energy electrons [PDF]

Scientific Reports, 2021
Very high energy electrons (VHEEs, E > 70 MeV) present promising clinical advantages over conventional beams due to their increased range, improved penumbra and relative insensitivity to tissue heterogeneities.

Laser-plasma generated very high energy electrons (VHEEs) in radiotherapy [PDF]

Proceedings of SPIE, 2017
As an alternative modality to conventional radiotherapy, electrons with energies above 50 MeV penetrate deeply into tissue, where the dose can be absorbed within a tumour volume with a relatively small penumbra. We investigate the physical properties of VHEEs and review the state-of-the-art in treatment planning and dosimetry. We discuss the advantages

Dosimetry and radioprotection evaluations of very high energy electron beams [PDF]

Scientific Reports, 2021
AbstractVery high energy electrons (VHEEs) represent a promising alternative for the treatment of deep-seated tumors over conventional radiotherapy (RT), owing to their favourable dosimetric characteristics. Given the high energy of the electrons, one of the concerns has been the production of photoneutrons.
