High-Current Low-Voltage Power Supplies for Superconducting Magnets

Émilien Luc Henri Coulinge, Drazen Dujic

In a synchrotron accelerator, the beam trajectory is controlled thanks to magnets, where superconducting technology allows to generate very strong magnetic fields. This was a key element in the construction of the Large Hadron Collider (LHC), the world lar ...

Real-time control of ELM and sawtooth frequencies: similarities and differences

Jonathan Graves

ELMs and Sawteeth, located in different parts of the plasma, are similar from a control engineering point of view. Both manifest themselves through quiescent periods interrupted by periodic collapses. For both, large collapses, following long quiescent per ...

Multi-scale modeling of elasto-plastic response of SnAgCu lead-free solder alloys at different ageing conditions: Effect of microstructure evolution, particle size effects and interfacial failure

Joël Cugnoni, John Botsis, Milad Maleki

In microelectronics applications, SnAgCu lead-free solder joints play the important role of ensuring both the mechanical and electrical integrity of the components. In such applications, the SnAgCu joints are subjected to elevated homologous temperatures f ...

R&D around a photoneutralizer-based NBI system (Siphore) in view of a DEMO Tokamak steady state fusion reactor

Philippe Frédérique Bruno Guittienne, Alan Howling, Ivo Furno, Rémy Jacquier

Since the signature of the ITER treaty in 2006, a new research programme targeting the emergence of a new generation of neutral beam (NB) system for the future fusion reactor (DEMO Tokamak) has been underway between several laboratories in Europe. The spec ...

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 ...

Effects of the Discharge Parameters on the Efficiency and Stability of Ambient Metastable-Induced Desorption Ionization

Mario Andres Chavarria Varon, Xiao Sheng Zhang

Ionization efficiency is an important factor for ion sources in mass spectrometry and ion mobility spectrometry. Using helium as the discharge gas, acetone as the sample, and high-field asymmetric ion mobility spectrometry (FAIMS) as the ion detection meth ...

On the use of electron capture rate constants to describe electron capture dissociation mass spectrometry of peptides

Yury Tsybin, Konstantin Zhurov, Aleksey Vorobyev, Unige Anna Laskay

Electron capture dissociation (ECD) tandem mass spectrometry (MS/MS) is a powerful analytical tool for peptide and protein structure analysis. The product ion abundance (PIA) distribution in ECD MS/MS is known to vary as a function of electron irradiation ...

Soft-landing electrospray ion beam deposition of sensitive oligoynes on surfaces in vacuum

Klaus Kern, Stephan Rauschenbach, Holger Frauenrath, Stephen Schrettl, Tobias Hoheisel, Gordon Rinke

Characterizing the complex structure of such molecules with highly resolving, vacuum-based methods like scanning probe microscopy requires their transfer into the gas phase and further onto an atomically clean surface in ultrahigh vacuum without causing ad ...

Guiding-centre transformation of the radiation-reaction force in a non-uniform magnetic field

Joan Decker

In this paper, we present the guiding-centre transformation of the radiation reaction force of a classical point charge travelling in a non-uniform magnetic field. The transformation is valid as long as the gyroradius of the charged particles is much small ...
