An inhomogeneous radio fquency electric field can couple the cyclotron and axid modes of a single icn in a Penning trap. The classical equations of motion are the same as those of a driven quantum mechanical two-level system. We discuss an analog of the A-pulse, which can exchange mode actions, and an analog of avoided crossing. Experimental illustrations are presented. PACS: 07.75.+h, 46.10.+z...

The ability to non-inductively drive a large fraction of the toroidal plasma current in magnetically confined plasmas is an essential requirement for steady state fusion reactors such as DEMO. Besides neutral beam injection (NBI), electron-cyclotron resonance heating (ECRH) and lower hybrid wave heating (LH), ion-cyclotron resonance heating (ICRH) is a promising candidate to drive current, in p...

Ion heating at the fundamental of the cyclotron resonance (1 M H z s 3 MHz) in a toroidal octupole magnetic field is found to be in good agreement with single particle, cold plasma theory at power levels PabrS 100 kW (E 5 100 Vlm) and ion temperatures kT, S 600 eV. Good penetration of the electric field is observed in the densest available plasmas (n7 x lo'* cmA3) with no evidence of parametric...

A method for direct and continuous detection of ion motion during different perturbation events of the fourier transform ion cyclotron resonance (FTICR) experiment is demonstrated. The modifications necessary to convert an ordinary FTICR cell into one capable of performing simultaneous excitation/detection (SED) using a capacitive network are outlined. With these modifications, a 200-fold reduc...

Exposure to electromagnetic fields is a research area that has generated conflicting results and thus uncertainty about possible adverse biological effects. This article analyzes the behavior of charged particles in a biological cell when exposed to different combinations of AC-DC electromagnetic fields, by combining the Ion ForcedVibration theory with the Ion Cyclotron Resonance and Ion Parame...
