Development and application of Eulerian and Particle-in-Cell gyrokinetic codes for studying the effect of non-adiabatic passing electron dynamics on microturbulence

Julien Stanislas Pierre Dominski

In tokamak fusion plasmas, micro-turbulence transport is known to be the cause of large losses of heat and particles. The present work deals with the study of electrostatic micro-turbulence transport driven by instabilities of essentially two types: the io ...

Measurement of e(+)e(-) -> pi(+)pi(-)psi(2S) via initial state radiation at Belle

Olivier Schneider, Yiming Li, Sun Hee Kim, Tara Nanut, Jun Yong Kim

We report measurement of the cross section of e(+)e(-) -> pi(+)pi(-)psi(2S) between 4.0 and 5.5 GeV, based on an analysis of initial state radiation events in a 980 fb(-1) data sample recorded with the Belle detector. The properties of the Y(4360) and Y(46 ...

Time-dependent frequency of ion motion in Fourier transform mass spectrometry

Yury Tsybin

Recent experimental and theoretical findings suggest that the concept of time-dependent instantaneous frequency(IF) is required to comprehensively describe ion motion and mass spectra generation in Fourier transform mass spectrometry (FTMS). Here, we deriv ...

Measurement of the Radial Profile of the Plasma Isotopic Composition in JET Plasmas Using Alfven Eigenmodes

Duccio Testa, Patrick Blanchard, Theodoros Panis

The measurement of the plasma isotopic composition is necessary in future burning plasma devices such as ITER and DEMO as a tool for optimizing the DT fusion performance. This paper reports on the results of experiments performed on the JET tokamak where T ...

Investigating profile stiffness and critical gradients in shaped TCV discharges using local gyrokinetic simulations of turbulent transport

Olivier Sauter, Laurent Villard, Stephan Brunner, Yann Camenen, Alessandro Marinoni, Gabriele Merlo

The experimental observation made on the TCV tokamak of a significant confinement improvement in plasmas with negative triangularity (delta < 0) compared to those with standard positive triangularity has been interpreted in terms of different degrees of pr ...

Ion coalescence in Fourier transform mass spectrometry: should we worry about this in shotgun proteomics?

Luca Fornelli

Coupling of motion of the ion clouds with close m/z values is a well-established phenomenon for ion-trapping mass analyzers. In Fourier transform ion cyclotron resonance mass spectrometry it is known as ion coalescence. Recently, ion coalescence was demons ...
