In tokamaks and stellarators, measurements of electromagnetic fluctuations in the presence of resonant particle drive, including fusion-produced alpha's, reveal the excitation of Alfven eigenmodes (AE), related under certain conditions to a degradation in ...
The Hamiltonian formulation of the guiding centre drift orbits for three-dimensional (3D) toroidal configurations with general time-dependent electric and magnetic field structures has been extended to cover relativistic particles. For static 3D magnetic f ...
Heating of tokamak plasmas up to temperatures of the order of 10 keV (≈ 108 0K) is one of the main subjects in plasma physics research. Much experimental and theoretical effort has been devoted to the improvement of the heating efficiency and to the unders ...
Two-dimensional Fourier transform (2D FT) spectroscopy was applied to ion-cyclotron resonance (ICR) to obtain direct evidence for mass transfer due to ion-mol. collisions. The 2D FT ICR expt., which is closely analogous to 2D exchange NMR spectroscopy (NOE ...
Ion cyclotron modes excited in a low density, cylindrical plasma cavity using an external inductive antenna are investigated theoretically and experimentally. These modes, which have a long parallel wavelength, exhibit a strong electrostatic character and ...
"The goal of this accelerator complex is to provide a 10 MW proton beam for driving the Energy Amplifier recently proposed by C. Rubbia [1]. It is lower (by one order of magnitude) than the requirements of most of the accelerator-ddrive projects based on c ...
"A high efficiency three-stage cyclotron has been proposed [1] to provide a 10 MW proton beam in the 1 GeV kinetic energy range for driving the Energy Amplifier. This accelerator complex consists of the following chain: two 15 MeV compact isochronous caylo ...
A modulated high frequency wave is used to remotely excite low frequency oscillations in a linear, strongly magnetized plasma column. An electromagnetic wave is launched as an extraordinary mode across the plasma by an external waveguide in the upper-hybri ...
A status report on the feasibility studies for the EULIMA medical accelerator project is given. Recent advances in the assessment of the various basic accelerator types ofr the facility are presented in terms of their advantages for heavy ion beam accelera ...
The linear relativistic theory of electron cyclotron wave propagation predicts partial absorption of the extraordinary mode at the third electron cyclotron harmonic for typical parameters of present day tokamak plasmas. Since the waves are not totally damp ...
