For instance, in Europe the large network of research centers "European Plasma Research Accelerator with eXcellence In Applications" (EUPRAXIA) has been created to develop the associated technologies and has just issued its expected Conceptual Design Report of reliable accelerators of this kind [6,7,8]. Among the present and future applications of accelerators we mention:…”

Light-front approach to relativistic electrodynamics

We illustrate how our recent light-front approach simplifies relativistic electrodynamics with an electromagnetic (EM) field F µν that is the sum of a (even very intense) plane travelling wave F µν t (ct−z) and a static part F µν s (x, y, z); it adopts the light-like coordinate ξ = ct−z instead of time t as an independent variable. This can be applied to several cases of extreme acceleration, both in vacuum and in a cold diluted plasma hit by a very short and intense laser pulse (slingshot effect, plasma wave-breaking and laser wake-field acceleration, etc.)1. E, B are constant or vary "slowly" in space/time; 2. the motion of the particle keeps non-relativistic;3. E, B are so small that nonlinear effects in E, B are negligible;4. E, B are monochromatic waves, or very slow modulations thereof.

We determine conditions allowing to simplify the description of the impact of a short and arbitrarily intense laser pulse onto a cold plasma at rest. If both the initial plasma density and pulse profile have plane simmetry, then suitable matched upper bounds on the maximum and the relative variations of the initial density, as well as the intensity and duration of the pulse, ensure a strictly hydrodynamic evolution of the electron fluid (without wave-breaking or vacuum-heating) during its whole interaction with the pulse, while ions can be regarded as immobile. We use a recently developed fully relativistic plane model whereby the system of the (Lorentz-Maxwell and continuity) PDEs is reduced into a family of highly nonlinear but decoupled systems of non-autonomous Hamilton equations with one degree of freedom, with the light-like coordinate ξ = ct−z instead of time t as an independent variable, and new apriori estimates (eased by use of a Liapunov function) of the solutions in terms of the input data (initial density and pulse profile). If the laser spot radius R is finite but not too small the same conclusions hold for the part of the plasma close to the axis z of cylindrical symmetry. These results may help in drastically simplifying the study of extreme acceleration mechanisms of electrons.

“…The huge accelerating fields (three orders of magnitude larger than conventional RF field used in accelerators) require a high degree of control of the beam parameters to reach the same stability and reliability of conventional accelerators. At the moment, several solutions are being investigated [33], ranging from laser-to particle-driven accelerators. The two case studies reported in this section are representative of two typical cases.…”

A Measurement Method Based on RF Deflector for Particle Bunch Longitudinal Parameters in Linear Accelerators

In high-brightness electron linear accelerators (LINACs), the particle bunch length is measured by a radio frequency deflector (RFD). The electron bunch is deflected vertically toward a screen and its length can be obtained using vertical spot size measurements after a proper calibration, e.g., measuring the vertical bunch centroid while varying the deflecting voltage phase. The energy parameters of the bunch (the energy chirp and the energy spread) and the correlation between particle positions, divergences, and energies contribute to the bunch vertical dimension at the screen position after the RFD and so far were considered as a source of systematic errors in a bunch length measurement. The measurement theory and production model for bunch length, energy spread and chirp, as well as correlations are described. As usual in particle accelerators physics, the method is validated using numerical simulations of state-of-the-art LINACs with a reference simulation code showing a typical accuracy in the few percent levels.
