A method for self consistent calculations of ion cyclotron resonance heating has been developed. The dielectric tensor is calculated from a particle distribution function calculated with the orbit averaged Monte Carlo code fido. The tensor is then fed into the global wave code lion. The calculated wave field and power partitions are fed back into the fido code. By using two existing codes in an...

The Doppler-shifted cyclotron resonance −kzvz= f between fast ions and shear Alfvén waves is experimentally investigated , wave frequency; kz, axial wavenumber; vz, fast-ion axial speed; f, fast-ion cyclotron frequency . A test particle beam of fast ions is launched by a Li+ source in the helium plasma of the LArge Plasma Device LAPD W. Gekelman, H. Pfister, Z. Lucky, J. Bamber, D. Leneman, and...

Two common bacteria, Streptococcus pyogenes and Pseudomonas aeruginosa, were differentiated based on their volatile metabolic waste products. The bacteria were cultured in a closed system and the headspace above the culture medium were collected, preconcentrated, and analyzed using a gas chromatography Fourier transform ion cyclotron resonance mass spectrometer (GC/FT-ICR MS).

Mechanistic aspects of the novel gas-phase generation of dibenzothiophene via coupling of thioanisole and chlorobenzene, employing atomic Ho(+) as a catalyst, have been investigated using Fourier-transform ion cyclotron resonance mass spectrometry in conjunction with density functional theory (DFT) calculations.

In order to be able to study complex biological samples, a micro-capillary liquid chromatography system was coupled to a 9.4 T Fourier transform ion cyclotron resonance mass spectrometer. The setup was tested on a tryptic digest of bovine serum albumin, which resulted in high sequence coverage (> 92%) of the protein.

To deal with the complexity of the glycan mixtures released from glycoproteins, an efficient form of micro-column separations, capillary electrochromatography, has been combined with high-performance mass spectrometry (Fourier transform ion cyclotron resonance). Contour plots have been generated from the mixtures of O-linked oligosaccharides originated from bovine mucin and bile salt-stimulated...

Numerical modelling of the effects of ion cyclotron resonance heating (ICRH) on the stability of the internal kink mode suggests that ICRH should be considered as an essential sawtooth control tool in ITER. Sawtooth control using ICRH is achieved by directly affecting the energy of the internal kink mode rather than through modification of the magnetic shear by driving localized currents. Conse...

The performance of Electron Cyclotron Resonance Ion Sources (ECRIS), producing high charge state ions from a great variety of elements, has improved dramatically over the past decades, thus enabling significant advances in accelerator-based nuclear physics. The orderof-magnitude performance leaps of ECR ion sources, e.g. from 15 μA of extracted O in 1974 [1] to 4700 μA in 2016 [2], result from ...
