Stimulated Brillouin back-scattering in mixed carbon and hydrogen plasmas is studied using one-dimensional Vlasov-Maxwell simulation. It is found that both the fast and slow ion acoustic waves can scatter the incident light. Carbon ions can be trapped in the slow ion acoustic wave, and the hydrogen ions can be trapped in both the fast and slow waves. The trapped ions tend to reduce the Landau damping of the ion acoustic waves, and both the fast and slow ion acoustic waves can be excited. From the time-integrated scattering spectra, the scattering peaks of the fast and slow ion acoustic waves can be clearly distinguished.

    All the Front End Test Stand (FETS) beam requirements have been achieved, but not simultaneously [1]. At 50 Hz repetition rates beam current droop becomes unacceptable for pulse lengths longer than 1 ms. This is fundamental limitation of the present source design. Previous researchers [2] have...

    To understand the plasma characteristics in the extraction region of hydrogen negative ion sources is very important for the optimization of H- extraction from the sources. The profile of plasma density in the extraction region is analyzed with a 2D PIC modeling of the NIFS-R&D H- sources. The...

    The application of fluid models in studies of transport and macroscopic stability of magnetized, nearly collisionless plasmas requires closure relations that are inherently nonlocal. Such closures address the fact that particles are capable of carrying information over macroscopic parallel scale...
