Towards an optimal antenna for helicon waves excitation

Helicon sources are known to produce high-density plasmas and have found many applications. Different types of antenna have been used for helicon excitation but none of them generate a radio-frequency (rf) field that matches the helicon wave field determin ...

Experimental observations of mode-converted ion cyclotron waves in a tokamak plasma by phase contrast imaging

Yu Lin

The process of mode conversion, whereby an externally launched electromagnetic wave converts into a shorter wavelength mode(s) in a thermal plasma near a resonance in the index of refraction, is particularly important in a multi-ion species plasma near the ...

Microwire arrays with plasmonic response at microwave frequencies

Olivier Martin

We study experimentally the response of three-dimensional arrays of microscopic wires. Very good agreement is found with previous theoretical work indicating that such a system can be considered as an effective plasmonic medium with a specific plasma frequ ...

Response of shielded cables to an external electromagnetic field excitation. Modeling and experimental validation

Michel Ianoz

Two methods for the calculation of internal responses of shielded cables submitted to an external impulse electromagnetic field are analyzed. One is the classical frequency-domain approach, the second is a new mixed frequency-time-domain model, which uses ...

Important design issues of a high efficiency cyclotron complex to drive the Energy Amplifier

Nicolas Fietier

"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 ...

Vibrational Overtone Spectra of Jet‐Cooled CF3H by Infrared Laser Assisted Photofragment Spectroscopy

Thomas Rizzo

Using our recently developed technique of infrared laser assisted photofragment spectroscopy (IRLAPS), we have measured four vibrational overtone bands of jet-cooled CF3H in the N = 4 and N = 5 CH stretch-bend polyads. The cooling in the expansion eliminat ...
