Analysis of plasma dynamic response to modulated electron cyclotron heating in TCV tokamak

The need of durable, economically acceptable and safe energy sources continues to stimulate studies in a field of thermonuclear fusion. The most successful solution for controlled magnetic fusion is the tokamak. The improvement of tokamak performance depen ...

Interference Mitigation for WCDMA using QR Decomposition and a CORDIC-based Reconfigurable Systolic Array

Robin Scheibler

This paper presents implementation and performance of QR Decomposition based Recursive Least-Squares (QRD-RLS) for interference mitigation in Wideband CDMA (WCDMA). The implementation is carried on CORSAEngine which is a new Software-Deﬁned Radio (SDR) pro ...

Plasma dynamics with second and third-harmonic ECRH and access to quasi-stationary ELM-free H-mode on TCV

Ambrogio Fasoli, Stefano Coda, Timothy Goodman, Yves Martin, Stefano Alberti, Patrick Blanchard, Laurie Porte, Henri Weisen, Mikhail Maslov, Andrea Scarabosio, Gilles Arnoux, Alessandro Bortolon

Intense electron cyclotron resonance heating (ECRH) and electron cyclotron current drive (ECCD) are employed on the Tokamak a Configuration Variable (TCV) both in second- and third-harmonic X-mode (X2 and X3). The plasma behaviour under such conditions is ...

VLSI implementation of a high-speed iterative sorted MMSE QR decomposition

Andreas Peter Burg

The QR decomposition is an important, but often underestimated prerequisite for pseudo- or non-linear detection methods such as successive interference cancellation or sphere decoding for multiple-input multiple-output (MIMO) systems. The ability of concur ...

Plasma production and transport in a simple magnetised toroidal plasma

Mario Ludovico Podesta

This Thesis addresses questions related to transport phenomena and the plasma production mechanisms by injection of microwaves in the electron-cyclotron frequency range in the simple magnetised toroidal plasma TORPEX. The second subject is investigated in ...

Electron cyclotron emission spectrometry on the Tokamak a Configuration Variable

Ambrogio Fasoli, Timothy Goodman, Stefano Alberti, Patrick Blanchard, Laurie Porte, Igor Klimanov

Electron cyclotron emission (ECE) measurements are an important component of the diagnostic suite on the Tokamak a Configuration Variable (TCV) [F. Hoffman , Plasma Phys. Controlled Fusion 36, B277 (1994)]. A recently installed, 24-channel dual-conversion ...

Toward sparse and geometry adapted video approximations

Oscar Divorra Escoda

Video signals are sequences of natural images, where images are often modeled as piecewise-smooth signals. Hence, video can be seen as a 3D piecewise-smooth signal made of piecewise-smooth regions that move through time. Based on the piecewise-smooth model ...

Application of the singular value decomposition method for inversion of interferometer measurements in fusion plasmas

Ivo Furno, Henri Weisen, Roland Behn, Emiliano Fable

We present applications of a recently developed method, the singular value decomposition inversion (SVD-I), for inverting line integrated multichannel interferometer measurements in fusion devices. The method expands the local electron density profiles int ...

High field side measurements of non-thermal electron cyclotron emission on TCV plasmas with ECH and ECCD

Stefano Coda, Stefano Alberti, Patrick Blanchard, Henri Weisen, Igor Klimanov, Petri Nikkola

Measurements of electron cyclotron emission (ECE) from the high field side of the TCV tokamak have been made on plasmas heated by second and third harmonic X-mode electron cyclotron heating (ECH) and electron cyclotron current drive (ECCD). Suprathermal EC ...
