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

open access: yesScientific 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.

Comparison of protons and very high-energy electrons transmission pencil-beam-scanning for FLASH radiotherapy [PDF]

open access: yesPhysics and Imaging in Radiation Oncology
Background and purpose: Very High-Energy Electron (VHEE) radiotherapy stands as a promising alternative to proton therapy in view of the FLASH effect, which allows for differential sparing of healthy tissues under ultra-high dose rate irradiation.

Start-to-end modelling of laser-plasma acceleration, beam transport and dose deposition of very high-energy electrons for radiotherapy [PDF]

open access: yesScientific Reports
The proposed radiotherapy using very high-energy electron (VHEE) beams generated by a laser-plasma accelerator has garnered significant interest due to its dose distribution capabilities and potential to address limitations of traditional photon-based ...

Statistical study of electron flux in Martian space environment

open access: yes地球与行星物理论评, 2022
The distributions of electrons at different regions in the Martian space environment play a significant role in the planet's evolution. However, the distributions of electrons in the entire Martian space remain unclear. Here, using MAVEN data during 2015~

Gamma-ray Bursts at the Highest Energies

open access: yesUniverse, 2021
Emission from Gamma-ray bursts is thought to be powered mainly by synchrotron radiation from energetic electrons. The same electrons might scatter these synchrotron seed photons to higher (>10 GeV) energies, building a distinct spectral component ...

Dosimetry for New Radiation Therapy Approaches Using High Energy Electron Accelerators

open access: yesFrontiers 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.
