Vlasov simulations of electron-ion collision effects on damping of electron plasma waves

Linear and Nonlinear Dust Acoustic Waves in Quantum Dusty Electron-Positron-Ion Plasma

The behavior of linear and nonlinear dust acoustic waves (DAWs) in an unmagnetized plasma including inertialess electrons and positrons, ions, and mobile positive/negative dust grains are studied. Reductive perturbation method is employed for small and finite amplitude DAWs. To investigate the solitary waves, the Korteweg–de Vries (KdV) equation is derived and the solution is presented. B...

Numerical simulation of ECRIPAC plasma behaviour with Vlasov equations including electron and ion collective effects

ECKIPAC is a new ion-electron accelerator concept using IXX, GYRAC and IUS4I~E effects, which is being studied in a collaboration betweeii (‘EA/l~KI;M~ (Grenoble), INS (Saclay) and GANII* ((‘am). A 611 Vlasov code using the “particle method” was dcvelopped to simulate the electron heating process, the plasma compression and the energy transfer from electrons to ions. Two versions are available ...

Damping of ion-acoustic waves in the presence of electron-ion collisions.

Implication of Quantum Effects on Non-Linear Propagation of Electron Plasma Solitons

We have studied the electron exchange-correlation effect on thecharacteristics of the two-component unmagnetized dense quantum plasma withstreaming motion. For this purpose, we have used the quantum hydrodynamic model(including the effects of a quantum statistical Fermi electron temperature) for studyingthe propagation of an electrostatic electron plasma waves in such th...

Ion Effects in the Slc Electron Damping Ring

We report on the ion-related beam behavior in the electron damping ring during unusually poor vacuum conditions in the weeks that followed a catastrophic kicker chamber failure that contaminated the ring vacuum system. The vacuum gradually improved over several months of beam operation, during which time the vertical emittance remained blown up by a factor of 2. The emittance blowup was accompa...
