Large open surgical approaches are being extensively replaced by endoscopic and robotic techniques. Yet, these developments have not been paralleled by the necessary improvements in tissue adaptation, fusion or fixation. In order to advance the surgical ar ...
Magnetic diagnostics for the new generation fusion reactor “ITER” are required to be extremely reliable since they provide measurements essential for reactor operation and protection, plasma control and for measurement of several parameters fundamental to ...
[...] The goal of this master project was to optimize the fusion pulse parameters in order to get a gentle and reproducible fusion. The experiments showed low fusion reproducibility and five different cell behaviours given the same electrical field was app ...
A key issue for steady-state tokamak operation is to determine the edge conditions that are compatible both with good core confinement and with the power handling and plasma exhaust capabilities of the plasma facing components (PFCs) and divertor systems. ...
The transition from a regime dominated by drift instabilities to a regime dominated by pure interchange instabilities is investigated and characterized in the simple magnetized toroidal device TORPEX [TORoidal Plasma EXperiment, A. Fasoli et al., Phys. of ...
Intermittent cross-field particle transport events (ITEs) are studied in the basic toroidal device TORPEX [TORoidal Plasma EXperiment, A. Fasoli et al., Phys. Plasmas 13, 055902 (2006)], with focus on the role of the density gradient. ITEs are due to the i ...
This PhD thesis consists of planning, simulating, building, testing and characterizing a new electron cyclotron resonance (ECR) ion source, SWISSCASE. the Solar Wind Ion Source Simulator for the CAlibration of Space Experiments located at the University of ...
This paper aims to contribute both to the ongoing process of scrape-off layer code-experiment and code-code benchmarking. Results are presented from SOLPS5 simulations of two high power JET H-modes with similar magnetic configuration, concentrating in the ...
The eigenmode spectrum is a fundamental starting point for the analysis of plasma stability and the onset of turbulence, but the characterization of the spectrum even for the simplest plasma model, ideal magnetohydrodynamics (MHD), is not fully understood. ...
In order to sort out the physics that is important in many plasma experiments, data in three dimensions 3D are becoming necessary. Access to the usual cylindrical vacuum vessel is typically restricted to radially or axially insertable probes that can pivot ...
