Interference and Shadow Effects in the Production of Light by Charged Particles in Optical Fibers
X. Artru, C. Ray
A charged particle passing through or near a narrow optical fiber induces, by polarisation, coherent light guided by the fiber. In the limit of zero crossing angle, the radiation t…
Complex networks in brain electrical activity
G. Ruffini, C. Ray, J. Marco +2
We analyze the complex networks associated with brain electrical activity. Multichannel EEG measurements are first processed to obtain 3D voxel activations using the tomographic al…
Electron acceleration in a helical waveguide
X. Artru, C. Ray
Travelling wave in a helical wave guide is considered for electron acceleration. A first determination of the travelling wave modes using a partial wave expansion (PWE) and a point…
Photon production by charged particles in narrow optical fibers
X. Artru, C. Ray
A charged particle passing through or by an optical fiber induces emission of light guided by the fiber. The formula giving the spontaneous emission amplitude are given in the gene…
Electron gas polarization effect induced by heavy H-like ions of moderate velocities channeled in a silicon crystal
D. Dauvergne, A. Bräuning-Demian, F. Bosch +17
We report on the observation of a strong perturbation of the electron gas induced by 20 MeV/u U ions and 13 MeV/u Pb ions channeled in silicon crystals. This collec…
Monitoring the Bragg peak location of 73 MeV/u carbon ions by means of prompt -ray measurements
E. Testa, M. Bajard, M. Chevallier +7
By means of a time-of-flight technique, we measured the longitudinal profile of prompt -rays emitted by 73 MeV/u C ions irradiating a PMMA target. This technique allowed…
