Electron trajectories in a realistic gyrotron resonator

open access: yesMathematical Modelling and Analysis, 1998
Gyrotron is a special tube generating powerful radiowaves in the millimeter wave range. Gyrotrons are mainly used to heat nuclear fusion plasma, in order to induce controlled thermonuclear reactions on earth.

Solar Cycle Detected in Natural Tritium of Ice Layers Before the Nuclear Era

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 9, 16 May 2025.
Abstract The 11‐year cycle of the solar activity affects the production rate of cosmogenic isotopes. For tritium in precipitation, it has been just recently proven that this link exists. Here we show, for the first time, a tritium ice core time series which extends back to 1923, covering a time period that avoids the presence of artificial tritium from

Transport of kJ-laser-driven relativistic electron beams in cold and shock-heated vitreous carbon and diamond

open access: yesNew Journal of Physics, 2020
We report experimental results on relativistic electron beam (REB) transport in a set of cold and shock-heated carbon samples using the high-intensity kilojoule-class OMEGA EP laser.

Hydrodynamic Scaling Analysis of Nuclear Fusion driven by ultra-intense laser-plasma interactions

open access: yes, 2012
We discuss scaling laws of fusion yields generated by laser-plasma interactions. The yields are found to scale as a function of the laser power. The origin of the scaling law in the laser driven fusion yield is derived in terms of hydrodynamic scaling ...

Fifty Years of Magnetic Fusion Research (1958–2008): Brief Historical Overview and Discussion of Future Trends

open access: yesEnergies, 2010
Fifty years ago, the secrecy surrounding magnetically controlled thermonuclear fusion had been lifted allowing researchers to freely share technical results and discuss the challenges of harnessing fusion power.

Analysis of Solar Radiation Shielding in Space for Climate Mitigations of the Earth

open access: yesEnergy Science &Engineering, Volume 13, Issue 4, Page 1653-1661, April 2025.
Space solar shielding over the Earth. ABSTRACT Solar radiation modification (SRM) through space solar shielding is a proposed strategy to mitigate global warming. This approach involves reflecting sunlight back into space while allowing Earth's infrared radiation to escape, thereby controlling climate change.

The e-ASTROGAM space mission: a major step forward for supernova physics

open access: yes, 2017
e-ASTROGAM is a gamma-ray observatory operating in a broad energy range, 0.15 MeV - 3 GeV, recently proposed as the M5 Medium-size mission of the European Space Agency.

Can We Draw Conclusions on Supernova Shock Wave Propagation Using Short‐Lived Radioactive Isotopes?

open access: yesAstronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.
ABSTRACT We run a three‐dimensional Galactic chemical evolution (GCE) model to follow the propagation of 53Mn (exclusively produced from type Ia supernovae, SNIa), 60Fe (exclusively produced from core‐collapse supernovae, CCSNe), 182Hf (exclusively produced from intermediate mass stars, IMSs), and 244Pu (exclusively produced from neutron star mergers ...
