Nonlinear Evolution of a Wave Packet in Electron-Beam-Plasma

Plasma Wave Acceleration of Electron in Bubble Regime in Presence of a Planar Wiggler

The plasma wave acceleration of electron in the bubble regime is investigated in a new configuration containing a planar wiggler. The space-charge field of the laser-created ion channel can focuse and stabilize the electron trajectory to guide it toward the acceleration region. The high-gradient plasma wave field can resonantly accelerate the trapped electron to higher energies in the presence ...

Growth and nonlinear evolution of the modified Simon-Hoh instability in an electron beam-produced plasma*

The growth and nonlinear evolution of the modified Simon–Hoh instability ~MSHI! is observed in a weak electron beam-produced collisionless cylindrical plasma, in which electrons are strongly magnetized and the ions are essentially unmagnetized. The evolution of this instability occurs through a sequence of sideband instabilities, thought to be induced by trapped ions, and a period doubling sequ...

Nonlinear Wave Dynamics In Two-Temperature Electron-Positron-Ion Plasma

The hot electron-positron unmagnetized plasma with small fraction of cold electron-ion plasma is investigated. The modulational interactions of the electromagnetic waves and the electron-sound waves are studied. The possibility of soliton formation is investigated.

Plasma Wave Observations During Electron Beam Experiments at High Altitudes

Electron beam experiments on the nearly geosynchronous P78—2 satellite conducted in 1979 resulted in observations of intense radiation near the local electron gyrofrequency. These signals resembled naturally occuring fCe waves during the same period. The amplitude of the stimulated waves depended upon beam parameters. During 50 eV beam operations, current levels of 10 pA produced strong emissio...
