Sunyaev Zel’dovich effect in galaxy clusters cavities: Thermal or non-thermal origin? [PDF]

open access: yesEPJ Web of Conferences, 2022
Several galaxy clusters host X-ray cavities, often filled with relativistic electrons emitting in the radio band. In the cluster MS 0735.6+7421 the cavities have been detected through the Sunyaev Zel’dovich (SZ) effect, but it has not been possible to ...

Resonant scattering of energetic electrons in the plasmasphere by monotonic whistler-mode waves artificially generated by ionospheric modification [PDF]

open access: yesAnnales Geophysicae, 2014
Modulated high-frequency (HF) heating of the ionosphere provides a feasible means of artificially generating extremely low-frequency (ELF)/very low-frequency (VLF) whistler waves, which can leak into the inner magnetosphere and contribute to resonant ...

Challenges of dosimetry of ultra-short pulsed very high energy electron beams [PDF]

open access: yesPhysica Medica, 2017
Very high energy electrons (VHEE) in the range from 100 to 250MeV have the potential of becoming an alternative modality in radiotherapy because of their improved dosimetric properties compared with 6-20MV photons generated by clinical linear accelerators (LINACs).

Observation of electron emission in the nuclear reaction between protons and deuterons

open access: yesPhysics Letters B, 2017
Proton–deuteron fusion reaction has been studied using a proton beam with an energy of 260 keV and a deuterium-implanted graphite target. The reaction product, 3He, usually de-excites by γ-ray emission.

Whispering gallery and surface mode of electrons in lateral and corrugated quantum dots

open access: yesMaterials Research Express, 2020
Quantum dots (QDs) are fundamental elements in the applications related to light–matter interaction, such as solar cells, lasers and sensors. Moreover, some modes of electrons including whispering galley modes (WGMs) and surface modes can be incorporated

Intense laser interaction with micro-bars

open access: yesScientific Reports, 2023
Intense laser fields interact very differently with micrometric rough surfaces than with flat objects. The interaction features high laser energy absorption and increased emission of MeV electrons, ions, and of hard x-rays.
