Very-High-Speed Slotless Permanent-Magnet Motors: Analytical Modeling, Optimization, Design, and Torque Measurement Methods

This paper presents a very-high-speed (VHS) slotless permanent-magnet motor design procedure using an analytical model. The model is used to design the optimal prototype (target: 200 kr/min, 2 kW). The multiphysics analytical model allows a quick optimizat ...

Progress and Scientific Results in the TCV Tokamak

Stefano Coda

The TCV tokamak has the dual mission of supporting ITER and exploring alternative paths to a fusion reactor. Its most unique tools are a 4.5 MW electron cyclotron resonance heating system with seven real-time controllable launchers and a plasma control sys ...

The Dependence of the Damping Rate of Medium-n Toroidal Alfvén Eigenmodes on the Edge Plasma Elongation in JET

Ambrogio Fasoli, Duccio Testa, Patrick Blanchard, Theodoros Panis, Nicolas Mellet

This paper reports the first quantitative analysis of the measurements of the damping rate (gamma/omega) for stable Alfvén Eigenmodes (AEs) with toroidal mode number (n) in the range |n|=3-15 as function of the edge plasma elongation (kappa95). We find tha ...

Plasma rotation and momentum transport studies in the TCV tokamak based on charge exchange spectroscopy measurements

Alessandro Bortolon

Thermonuclear controlled fusion research is a highly active branch of plasma physics. The main goal is the production of energy from the fusion reaction of hydrogen isotope nuclei, the same reaction that powers stars. The most promising present approach ar ...

Plasma fluctuation studies in the TCV tokamak

Alessandro Marinoni

One of the most important issues for magnetic-confinement fusion research is the so-called anomalous transport across magnetic field lines, i.e. transport that is in excess of that caused by collisional processes. The need to reduce anomalous transport in ...

Field-induced magnetic phases and electric polarization in LiNiPO4

Henrik Moodysson Rønnow

Neutron diffraction is used to probe the (H,T) phase diagram of magnetoelectric (ME) LiNiPO4 for magnetic fields along the c axis. At zero field the Ni spins order in two antiferromagnetic phases. One has commensurate (C) structures and general ordering ve ...

Real-time feedback control of millimeter-wave polarization for LHD

Olivier Sauter, Timothy Goodman, Federico Alberto Alfredo Felici

Electron cyclotron heating (ECH) is widely used in magnetic fusion devices, and the polarization of the injected millimeter-wave beams plays a crucial role in the propagation and absorption of the beam energy by the plasma. This polarization can be adjuste ...

Polarization Issues with High Power Injection and Low Power Emission in Fusion Experiments

Timothy Goodman, Federico Alberto Alfredo Felici

All tokamak experiments using ECCD require setting of the beam elliptical polarization for proper coupling to the plasma. This is done either in the matching optics unit (MOU) at the output of the gyrotron, or in a couple of miter bends of the transmission ...

Drift-free magnetic equilibrium reconstruction using the response to plasma position modulation

Jonathan Bryan Lister

Inductive magnetic sensors are widely used for plasma equilibrium reconstruction and control. However, their measurements involve electronic integration and can therefore experience drift leading to inaccurate plasma positioning. For this reason, we have s ...
