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.

Extension of the Synchrotron Radiation of Electrons to Very High Energies in Clumpy Environments [PDF]

The Astrophysical Journal, 2021
Abstract The synchrotron cooling of relativistic electrons is one of the most effective radiation mechanisms in astrophysics. It not only accompanies the process of particle acceleration, but also has feedback on the formation of the energy distribution of the parent electrons.

A focused very high energy electron beam for fractionated stereotactic radiotherapy [PDF]

Scientific Reports, 2021
AbstractAn electron beam of very high energy (50–250 MeV) can potentially produce a more favourable radiotherapy dose distribution compared to a state-of-the-art photon based radiotherapy technique. To produce an electron beam of sufficiently high energy to allow for a long penetration depth (several cm), very large accelerating structures are needed ...

VHEeP: a very high energy electron–proton collider [PDF]

The European Physical Journal C, 2016
Based on current CERN infrastructure, an electron--proton collider is proposed at a centre-of-mass energy of about 9 TeV. A 7 TeV LHC bunch is used as the proton driver to create a plasma wakefield which then accelerates electrons to 3\,TeV, these then colliding with the other 7 TeV LHC proton beam.

Dosimetry for New Radiation Therapy Approaches Using High Energy Electron Accelerators

Frontiers in Physics, 2020
We have performed dosimetry studies using electron beams with energies up to 50 MeV, which exceed current clinical energy ranges and approaches the bottom end of the very high energy electron range. 50 MeV electron beams can reach deep-seated tumors.

Treatment planning of intracranial lesions with VHEE: comparing conventional and FLASH irradiation potential with state-of-the-art photon and proton radiotherapy

Frontiers in Physics, 2023
The treatment of deep-seated tumours with electrons of very high energies (VHEE, 70–150 MeV) has already been explored in the past, suggesting that a dosimetric coverage comparable with state-of-the-art proton (PT) or photon radiotherapy (RT) could be ...

A Geant4 Fano test for novel very high energy electron beams

Physics in Medicine & Biology, 2021
Abstract Objective. The boundary crossing algorithm available in Geant4 10.07-p01 general purpose Monte Carlo code has been investigated for a 12 and 200 MeV electron source by the application of a Fano cavity test. Approach. Fano conditions were enforced

Focused VHEE (very high energy electron) beams and dose delivery for radiotherapy applications [PDF]

Scientific Reports, 2021
AbstractThis paper presents the first demonstration of deeply penetrating dose delivery using focused very high energy electron (VHEE) beams using quadrupole magnets in Monte Carlo simulations. We show that the focal point is readily modified by linearly changing the quadrupole magnet strength only.
