The Low Energy Ion Ring (LEIR) is a central piece for LHC ion operation at CERN, transforming long Linac3 pulses into high density bunches needed for LHC. The first phase of LEIR commissioning successfully attained its goal of providing the so-called “early ion beam” (one bunch of 2.25 10 Lead ions) needed for the first LHC ion runs with reduced luminosity. Studies in view of generating the bea...
Linear colliders, such as the SLC, are among those accelerators for which a high-yield positron source operating at the repetition rate of the accelerator is desired. The SLC, having electron energies up to 50 GeV, presents the possibility of generating positron bunches with useful charge even exceeding that of the initial electron bunch. The exact positron yield to be obtained depends on the p...
Emission of light by a single electron moving on a curved trajectory (synchrotron radiation) is one of the most well-known fundamental radiation phenomena. However experimental situations are more complex as they involve many electrons, each being exposed to the radiation of its neighbors. This interaction has dramatic consequences, one of the most spectacular being the spontaneous formation of...

Le Pimpec Paul Scherrer Institute, 5232 Villigen PSI, Schweiz Abstract Beam instability caused by the electron cloud has been observed in positron and proton storage rings and it is expected to be a limiting factor in the performance of ...
Side-coupled standing wave tubes in mode are widely used in the low-energy electron linear accelerator, due to high accelerating gradient and low sensitivity to construction tolerances. The use of various simulation software for designing these kinds of tubes is very common nowadays. In this paper, SUPERFISH code and COMSOL are used for designing the accelerating and coupling cavities for a 6 ...
Storage rings are extensively used for particle colliders, damping rings and light sources. To further increase the luminosity at the colliders or brightness of a synchrotron light sources, the emittance of accelerator beam is being continually pushed downward in storage rings. In this paper, we investigate the lattice design for the storage ring of Iranian Light Source Facility (ILSF) with an ...
