If the average magnetic field inside the orbit is always twice as strong as the magnetic field on the orbit, the radius of the orbit remains constant, so that the acceleration chamber can be made in the shape of a torus, or doughnut. The poles of the magnet are tapered to cause the ...
c1 and c2 are the acceleration constants, which are used to adjust the search step of the particle29. r1 and r2 are two random uniform values distributed in the range [0,1], which are used to improve the randomness of the particle search. ω inertia weight parameter, which is used to ...

20. Earlier studies on laser driven charged particle acceleration as discussed in the previous paragraph had neglected radiation reaction effects. It turns out that in the presence of radiation reaction effects both the constants of motion i.e. [Math Processing Error]P→⊥ and [Math Processing ...
A significant range in the Kolmogorov, turbulent, and acceleration Stokes numbers was covered. The times-of-flight were used to analyze the dispersion measurements in terms of Lagrangian statistics. Dispersion data at long times of flight for a range of nozzle diameters, particle diameters and exit...
Under a Creative Commons license open accessAbstract A new two-phase incompressible–compressible Smoothed Particle Hydrodynamics (SPH) method has been developed where the interface is discontinuous in density. This is applied to water–air problems with a large density difference. The incompressible phas...
These two different scaling schemes generate self-similar systems of the acceleration channel including the process of secondary electron emission from the dielectric walls. Instead of using the common approach of a smaller neutral and ion mass or a larger vacuum permittivity the channel dimensions are...

(ref.5), as often observed10. For a turbulent field in the plasma crossing a shock front, particle acceleration should be most efficient in cells for which the magnetic field is nearly parallel to the shock normal; this bias leads to a higher value ofΠand more pronounced variability at X...
Indeed, each bounce of the droplet imprints a standing long-lasting axisymmetric wave centered at the point of impact, which lifetime is controlled by the vertical acceleration magnitude of the bath. In this system, because the droplet slides down the gradient of the local liquid surface, the ...
