Many of today’s most advanced research infrastructures rely on the use of particle accelerators. This includes for example synchrotron-based light sources and FELs, high energy accelerators for particle physics experiments, high intensity hadron accelerators for the generation of exotic beams and spallation sources, as well as much smaller accelerator facilities where cooled beams of specific...

The Large Hadron Collider (LHC) at CERN has been operated for three years for physics leading to the discovery of a Higgs boson. The operational experience will be reviewed together with the main challenges encountered and the solutions applied. The performance outlook after the long shut-down and the future upgrade plans will be discussed with particular emphasis on the beam dynamics aspects.

In 2012 two LHC experiments have discovered a new particle with a mass around 125 GeV, which appears to be the scalar Higgs boson of the Standard Model. To further examine this remarkable particle it could be produced in large numbers for precision studies by an e+e− collider operating near the ZH threshold at beam energies of 120 GeV, or, in the s-channel by a gamma-gamma collider with...

Third generation synchrotron light sources under operation have reached very low emittances (1-5 nm.rad) at energies of a few GeV. Linear and nonlinear beam dynamics optimizations of their storage ring lattices are complex but well mastered. An overview of the procedures used for the optimization will be shown in this talk together with the performance of the latest generation of operating...

The MAD in its F77 incarnation of version 8 has been very successful in the 90's and is used around the world even today. The LHC design tool was supposed to be MAD9 written from scratch in C++. Since this failed, despite a major 5 years effort, the MAD-X project was started. In early 2000 Hans Grote and a team of module keepers had to construct a C & F77 hybrid code within 6 months to provide...

The high intensity frontier in accelerator science drives development in fields as varying as neutrino physics, material science and life sciences with neutrons, rare decays searches and transmutation. The accelerators used can broadly be divided into high average intensity hadron machines, high instantaneous intensity hadron machines and high intensity electron/positron machines. I will give...

Beam instrumentation encompasses all instruments that observe beam behaviour, providing “eyes” for machine operators. Good beam instrumentation is a must for safe and efficient accelerator optimisation. Today's main challenges lie in the request for unprecedented precision with positioning down to well below the micron level; dealing with high beam powers requiring non-invasive measurement...

In this talk a wide overview of the current state of the art of facilities that produce low energy/low intensity beams will be presented. Performances and R&D activities will be described, also putting in evidence the future plans for the improvements. The main facilities producing radioactive ion beams will be also presented, with an accurate description of the related beam diagnostics.

At the Large Hadron Collider (LHC), proton beam losses must be controlled to unprecedented levels of accuracy as there are about 9 orders of magnitudes between the beam stored energy ad the quench limits of superconducting magnets. This poses critical challenges for the simulations of collimation performance that must provide accurate estimates with appropriate statistics of beam losses at...

The main principles of particle detectors will be reviewed together with some key parameters that determine their design and specifications, namely vertex measurement, particle momentum and energy measurement as well as particle identification. Present LHC detectors are used for illustration of these topics. The challenges for future particle detectors are then discussed by using the plans for...

With peak brightness ten orders of magnitude higher than any other X-ray source and pulses as short as a few femtoseconds, Free Electron Lasers (FELs) have opened new regimes in photon science. This talk will begin by describing the basic principles behind X-ray FELs and the accelerator performance requirements that make them possible, using SLAC's Linac Coherent Light Source (LCLS) as an...

A review of tools for electromagnetic field simulations used at CERN will be given. A number of examples of its usage will be presented covering several areas of accelerator component design and optimization both RF and non-RF equipment: accelerating cavities, collimation devices, etc. Furthermore, brief review of CLIC main linac RF frequency and accelerating gradient optimization will be...

Traditionally magnets for particle accelerators have been based on electromagnetic generation of the magnetic field. A new Green Magnet® technology based on permanent magnets requires close to zero electrical power, no cooling water, and it saves cost, space and natural resources. The technology has been developed as a collaborative R&D project between industry and academia. The performance of...

A focused electromagnetic field represents an extreme electromagnetic field. Maybe the highest electric field we can get under controlled conditions? One electric charge inside that field is subject to a tremendous force and it is thus accelerated to relativistic speeds on a few femtoseconds (lab frame time). The relativistic motion of a charged field inside an extreme laser is going to be...

During the 2010-2012 LHC run I, the accelerator delivered a wealth of data to the four large and several smaller experiments at the four collision points, allowing significant advances in our knowledge of high-energy physics and culminating in the discovery of a Higgs boson in 2012. This talk will give an overview of the LHC experiments and physics program, with a particular emphasis on...
