PEBSI - A Monte Carlo simulator for bremsstrahlung arising from electrons colliding with thin solid-state targets
Monte Carlo simulation polarized electrons bremsstrahlung polarization target-thickness effects hard x-ray
2012/5/31
We present a Monte Carlo code dedicated to the simulation of bremsstrahlung arising in collisions of polarized electrons with thin target foils. The program consists of an electron transport algorithm...

The features of Betatron X-ray emission produced in a laser-plasma accelerator are closely linked to the properties of the relativistic electrons which are at the origin of the radiation. While in int...
Criteria to define a pair-ion plasma and the role of electrons in nonlinear dynamics
Criteria, pair-ion plasma, ion acoustic wave
2011/8/31
A criterion to define a pure pair-ion (PI) plasma is presented. It is suggested that the lighter elements (like H and He) are more suitable to produce PI plasmas. The observation of ion acoustic wave ...
