Gentle quantitative measurement of helium density in nanobubbles in silicon by spectrum imaging

Cécile Hébert, Duncan Thomas Lindsay Alexander, Guillaume Lucas

We propose an original method for the determination of the physical properties of nanometer sized helium bubbles using spectrum imaging in an energy-filtered transmission electron microscope. Helium bubbles synthesized by high fluence implantation and ther ...

First operations with the new Collective Thomson Scattering diagnostic on the Frascati Tokamak Upgrade device

Cristian Galperti, Gabriele Grosso

Anomalous emissions were found over the last few years in spectra of Collective Thomson Scattering (CTS) diagnostics in tokamak devices such as TEXTOR, ASDEX and FTU, in addition to real CTS signals. The signal frequency, down-shifted with respect to the p ...

Novel aspects of plasma control in ITER

Olivier Sauter, Federico Alberto Alfredo Felici, Jonathan Bryan Lister, Sun Hee Kim

ITER plasma control design solutions and performance requirements are strongly driven by its nuclear mission, aggressive commissioning constraints, and limited number of operational discharges. In addition, high plasma energy content, heat fluxes, neutron ...

No DDRama at chromosome ends: TRF2 takes centre stage

Antonio Porro, Liuh-Yow Chen, Sascha Feuerhahn

Telomeres are nucleoprotein structures capping the natural termini of eukaryotic linear chromosomes. Telomeres possess an inherent ability to circumvent the activation of a full-blown DNA damage response (DDR), and hence fusion reactions, by limiting inapp ...

The interaction between neutral particles and turbulent plasma in the tokamak SOL

Paolo Ricci, Federico David Halpern, Fabio Riva, Christoph Wersal

The first-principle understanding of the processes in the Scrape-Off-Layer (SOL) of a tokamak is crucial for the development of a thermonuclear reactor. Since the plasma temperature in the SOL is rather low, the plasma is typically not fully ionized, and t ...

Fold-based fusion as a library: a generative programming pearl

Sandro Stucki, Manohar Jonnalagedda

Fusion is a program optimisation technique commonly implemented using special-purpose compiler support. In this paper, we present an alternative approach, implementing fold-based fusion as a standalone library. We use staging to compose operations on folds ...

Nondiffusive transport regimes for suprathermal ions in turbulent plasmas

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Kyle Gustafson, Alexandre Dominique Bovet

The understanding of the transport of suprathermal ions in the presence of turbulence is important for fusion plasmas in the burning regime that will characterize reactors, and for space plasmas to understand the physics of particle acceleration. Here, thr ...

Experimental Validation of a Filament Transport Model in Turbulent Magnetized Plasmas

Nicola Vianello, Heinz Mueller

In a wide variety of natural and laboratory magnetized plasmas, filaments appear as a result of interchange instability. These convective structures substantially enhance transport in the direction perpendicular to the magnetic field. According to filament ...
