Abstract A two-dimensional, full-wave, frequency domain, cold plasma model is used to study electromagnetic power propagation and absorption in a helicon thruster, including its far plume region surrounding space. Results show that fraction of absorbed the region, deposition source essentially unperturbed by simulation domain size, presence metallic obstacles, or density environment. An electro...
We present high resolution measurements of the ultrafast temporal dynamics of the critical surface in moderately overdense, hot plasma by using two-color, pump-probe Doppler spectrometry. Our measurements clearly capture the initial inward motion of the plasma inside the critical surface of the pump laser which is followed by outward expansion. The measured instantaneous velocity and accelerati...
An electromagnetic wave is expected to propagate through an overdense plasma, provided that its amplitude is large enough to bring the electron motion into the relativistic regime. We study this induced transparency by using 1D and 2D particle simulations. We find that large chaotic longitudinal electric fields are generated and strong plasma heating takes place during the propagation. This beh...
We use an Eulerian Vlasov code to study the problem of the amplification of seed pulses by Brillouin backscattering in the strong-coupling regime. In this process, there is an energy transfer, mediated by a resonant ion wave, from a long, high energy pump electromagnetic wave, to an initially counter-propagating ultra-short seed pulse. The code solves the onedimensional Vlasov-Maxwell set of eq...
