Building and maintaining control systems for high-energy physics is becoming an increasingly complex and costly activity. The quickly evolving technology and the tight budget conditions require today a better management of our engineering activities. This situation led us to organize these activities as "projects" and to use modern project management practices already widely spread in industry....

We derive compact analytical formulae of the Bonneau-Martin type for the reaction e + e − → ¯ f f γ with cuts on minimal energy and acollinearity of the fermions, where the photons may be emitted both from the initial or final states. Soft photon exponentiation is also taken into account. One of the cleanest scattering processes at elementary particle accelerators is fermion-pair production in ...

− The paper deals with a fast measurement technique of electromagnetic transients due to eddy currents in fast-cycled magnets for linear particle accelerators. First the context of the problem, related to the need for accurate control of the magnetic field quality in order to ensure the stability and performance of the particle beam in dynamic conditions (field ramps up to about 700 T/s) is out...

The understanding of laser beam propagation through underdense plasmas is of vital importance to laser-plasma interaction experiments, as well as being a fundamental physics issue. Formation of plasma channels has numerous applications including table-top xray lasers and laser-plasma-produced particle accelerators. The fast ignitor concept, for example, requires the formation of an evacuated ch...

A brief introduction to electron and ion sources for particle accelerators is given. Concentrating on the basic processes for the production of these particles, thermionic and photocathode production of electrons and the processes in Penning and electron cyclotron resonance ion sources are covered. Finally, negative ions are discussed.

This author's recent proposal of interferometric tests of Planck-scale-related properties of space-time is here revisited from a strictly phenomenological viewpoint. The results announced previously are rederived using elementary dimensional considerations. The dimensional analysis is then extended to the other two classes of experiments (observations of neutral kaons at particle accelerators a...

034402-1 Low-energy, background electrons are ubiquitous in high-energy particle accelerators. Under certain conditions, interactions between this electron cloud and the high-energy beam can give rise to numerous effects that can seriously degrade the accelerator performance. These effects range from vacuum degradation to collective beam instabilities and emittance blowup. Although electron-clo...
