Observation of short time-scale spectral emissions at millimeter wavelengths with the new CTS diagnostic on the FTU tokamak

Cristian Galperti, Gabriele Grosso

On the FTU tokamak, the collective Thomson scattering (CTS) diagnostic was renewed for investigating the possible excitation of parametric decay instabilities (PDI) by electron cyclotron (EC) or CTS probe beams in presence of magnetic islands and measure t ...

Device and Method for Ion Cyclotron Resonance Mass Spectrometry

Yury Tsybin, Anton Kozhinov, Konstantin Nagornov

The present invention relates to a method and device for measuring m/z ratios of ions in ion cyclotron resonance (ICR) mass spectrometry. The described ion traps for ICR mass spectrometry are distinct from the previous configurations by having one or many ...

Optimization of ICRH for core impurity control in JET-ILW

Jonathan Graves

Ion cyclotron resonance frequency (ICRF) heating has been an essential component in the development of high power H-mode scenarios in the Jet European Torus ITER-like wall (JET-ILW). The ICRF performance was improved by enhancing the antenna-plasma couplin ...

Mechanical analyses of the waveguide flange coupling for the first confinement system of the ITER electron cyclotron upper launcher

Timothy Goodman, René Chavan, Jean-Daniel Landis, Robert Bertizzolo

The four electron cyclotron (EC) upper port antennas (or "upper launchers" -UL) will be used to drive current locally inside magnetic islands located at the q= 2 (or smaller) rational surfaces in order to stabilize neoclassical tearing modes (NTMs), as wel ...

High-beta, steady-state hybrid scenario on DIII-D

Holger Reimerdes

The potential of the hybrid scenario (first developed as an advanced inductive scenario for high fluence) as a regime for high-beta, steady-state plasmas is demonstrated on the DIII-D tokamak. These experiments show that the beneficial characteristics of h ...

Progress on the upgrade of the TCV EC-system with two 1MW dual-frequency gyrotrons

Stefano Alberti, Timothy Goodman, Minh Quang Tran, Jean-Philippe Hogge, Jérémy Genoud, Trach-Minh Tran, Ioannis Pagonakis, Konstantinos Avramidis

The upgrade of the electron cyclotron (EC) system of the TCV tokamak has entered in its realization phase. The MW-class dual-frequency gyrotron design (84 or 126GHz/2s), based on the 140GHz W7-X gyrotron, is finalized and a contract for the manufacturing o ...
