Propagation of gamma rays and production of free electrons in air
Propagation of gamma rays production of free electrons Plasma Physics
2012/4/20
A new concept of remote detection of concealed radioactive materials has been recently proposed \cite{Gr.Nusin.2010}-\cite{NusinSprangle}. It is based on the breakdown in air at the focal point of a h...
Controlled Betatron X-ray radiation from tunable optically injected electrons
Betatron X-ray radiation tunable optically injected electrons
2011/9/5
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 ...
