Mitigation of intensity limitation in the CERN SPS using a double RF system

The Super Proton Synchrotron (SPS) at CERN is the injector of the Large Hadron Collider (LHC). Multi-bunch instabilities limit the intensity of the beam that can be accelerated to 450 GeV in the SPS and transferred to the LHC. Without mitigation measures, ...

Insights into Reaction Intermediates to Predict Synthetic Pathways for Shape-Controlled Metal Nanocrystals

Anne-Clémence Corminboeuf, Raffaella Buonsanti, Anna Loiudice, Valeria Mantella, Pranit Srinivas Iyengar, Michal Stanislaw Strach, James Richard Pankhurst, Shubhajit Das

Understanding nucleation phenomena is crucial across all branches of physical and natural sciences. Colloidal nanocrystals are among the most versatile and tunable synthetic nanomaterials. While huge steps have been made in their synthetic development, syn ...

High-gradient and high-efficiency linear accelerators for hadron therapy

Stefano Benedetti

Hadron beams - approximately 200 MeV protons and 400 MeV/u fully stripped carbon ions - are better suited to treat deep-seated tumours than X ray beams - produced by electrons accelerated by linear accelerators (linacs) to 5-25 MeV - because they leave the ...

Synchrotron light: A success story over six decades

Giorgio Margaritondo

Synchrotron radiation research continues to be a major factor in the progress of science and technology, as it has been for more than half a century. We present different aspects of its history, starting with an unconventional approach: a fictional version ...

The relativistic foundations of synchrotron radiation

Giorgio Margaritondo

Special relativity (SR) determines the properties of synchrotron radiation, but the corresponding mechanisms are frequently misunderstood. Time dilation is often invoked among the causes, whereas its role would violate the principles of SR. Here it is show ...

Axisymmetric oscillations at L-H transitions in JET: M-mode

Nicola Vianello, Antonio José Pereira de Figueiredo, Bernhard Sieglin

L to H transition studies at JET have revealed an n = 0, m = 1 magnetic oscillation starting immediately at the L to H transition (called M-mode for brevity). While the magnetic oscillation is present a weak ELM-less H-mode regime is obtained, with a clear ...

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 ...

Monte Carlo simulations of ultra high vacuum and synchrotron radiation for particle accelerators

Márton Ady

With preparation of Hi-Lumi LHC fully underway, and the FCC machines under study, accelerators will reach unprecedented energies and along with it very large amount of synchrotron radiation (SR). This will desorb photoelectrons and molecules from accelerat ...

Modeling and characterization of grain structures and defects in solidification

Michel Rappaz

The paper by Karma and Tourret (this volume) in this special issue focuses on multiscale modeling approaches ranging from atoms to microstructure. In the present one, the most recent and significant modeling contributions dealing with the scale of solidifi ...
