The 16 T Dipole Development Program for FCC and HE-LHC

Pierluigi Bruzzone, Stephan Russenschuck, Peng Gao, Luca Bottura, Mariusz Juchno, Bernhard Auchmann, Giuseppe Montenero

A future circular collider (FCC) with a center-of-mass energy of 100 TeV and a circumference of around 100 km, or an energy upgrade of the LHC (HE-LHC) to 27 TeV require bending magnets providing 16 Tin a SO-mm aperture. Several development programs for th ...

IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2019

The Large Hadron Collider (LHC) at CERN is being prepared for its full energy exploitation during Run III, i.e. an increase of the beam energy beyond the present 6.5 TeV, targeting the maximum discovery potential attainable. This requires an increase of th ...

The ACHIP experimental chambers at the Paul Scherrer Institut

Leonid Rivkin, Rasmus Ischebeck, Eugenio Ferrari, Sven Reiche, Christian David

The Accelerator on a Chip International Program (ACHIP) is an international collaboration, funded by the Gordon and Betty Moore Foundation, with the goal of demonstrating that laser-driven accelerator can be integrated on a chip to fully build an accelerat ...

Rare Earth and Bimetallic Transition Metal Islands at Surfaces

Dimitrios Mousadakos

This thesis reports on the growth and on the magnetic characterization of nanostructures made of 3d-4d transition metals and rare earths. In all the experiments the nanostructures have been grown by atomic beam epitaxy (ABE) in ultra high vacuum conditions ...

High-Current Low-Voltage Power Supplies for Superconducting Magnets

Drazen Dujic, Émilien Luc Henri Coulinge

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 ...

Robust metastable skyrmions and their triangular-square lattice structural transition in a high-temperature chiral magnet

Henrik Moodysson Rønnow, Jonathan White

Skyrmions, topologically protected nanometric spin vortices, are being investigated extensively in various magnets(1-11). Among them, many structurally chiral cubic magnets host the triangular-lattice skyrmion crystal (SkX) as the thermodynamic equilibrium ...

Merged neutral beams

Andreas Osterwalder

A detailed description of a merged beam apparatus for the study of low energy molecular scattering is given. This review is intended to guide any scientist who plans to construct a similar experiment, and to provide some inspiration in describing the appro ...

Investigations of Quench Limits of the LHC Superconducting Magnets

Minh Quang Tran, Bernd Dehning, Agnieszka Priebe

NbTi-based Rutherford cables are used in the coils of the Large Hadron Collider (LHC) magnets. These cables are designed to operate with currents up to 13 kA at temperatures of 1.9 K. Beam losses can locally heat the superconducting cables above the critic ...

Growth and Magnetism of Nanostructures Investigated by STM, MOKE, and XMCD

Alberto Cavallin

This thesis presents our studies on nanostructures growth and magnetism, mainly based on scanning tunneling microscopy (STM), magneto-optical Kerr effect (MOKE), and x-ray magnetic circular dichroism (XMCD) measurements. In most of these experiments, nanos ...

Magnetic Model of the CERN Proton Synchrotron

Mariusz Juchno

In this thesis, we present development of the first magnetic model of the main Proton Synchrotron magnets. The operation of the machine and conducting research on increasing its performance require a significant amount of the magnetic field data for the op ...
