Using the SDvision 3D visualization software developed within the framework of IDL Object Graphics at CEA/IRFU, we have visualized the travel of charged particles in the IFMIFEVEDA accelerator. Simulations visualized here were made for a beam composed of 1 million macroparticles. To ensure that beam losses do not exceed 1W/m in the high energy part, simulations with 4,000,000,000 particles were...

Synchrotron particle accelerators are mainly composed of magnets. Long dipole magnets are employed to bend and to contain the beam within a circular trajectory. Their field quality is usually tested by arrays of rotating coils. Typically the measurements must be affected by low uncertainty (+10) and the calibration of the sensing coils, in terms of surface and angle, is critical. In this paper,...

This is a summary of Session C of the ECLOUD’04 workshop. The session was dedicated to Surface Properties, Measurements and Treatments. Much progress has been achieved in particle accelerator laboratories in the understanding and finding possible treatments to reduce the secondary electron yield at the surface and cure the electron cloud effect.

The working group on beam quality, diagnostics, and control at the 12th Advanced Accelerator Concepts Workshop held a series of meetings during the Workshop. The generation of bright charged-particle beams (in particular electron and positron beams), along with state-ofthe-art beam diagnostics and synchronization were discussed.

Quarks are widely recognized today as being among the elementary particles of which matter is composed. The key evidence for their existence came from a series of inelastic electron-nucleon scattering experiments conducted between 1967 and 1973 at the Stanford Linear Accelerator Center. Other theoretical and experimental advances of the 1970s confirmed this discovery, leading to the present sta...

The strong electromagnetic fields associated with ultra-relativistic protons and nuclei correspond to an equivalent flux of photons. At the future Large Hadron Collider at CERN, the corresponding photon-nucleon center of mass energies will be higher than at any existing accelerator. The experimental and theoretical aspects of particle production in electromagnetic interactions at hadron collide...
