Beam Injection Experiments using Space Charge Lenses
Space charge lenses for ion beam focussing are in theory, especially for singly charged heavy ion beams at low velocities, superior to other lens systems [1]. On the other hand previous experiments [2] have shown, in contrary to the theoretical forecast, a small degree of lens filling and serious emittance growth. Newer experiments [3] demonstrated a much better degree of lens filling and subst...
متن کاملElectron self-injection and trapping into an evolving plasma bubble.
The blowout (or bubble) regime of laser wakefield acceleration is promising for generating monochromatic high-energy electron beams out of low-density plasmas. It is shown analytically and by particle-in-cell simulations that self-injection of the background plasma electrons into the quasistatic plasma bubble can be caused by slow temporal expansion of the bubble. Sufficient criteria for the el...
متن کاملPlasma 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...
متن کاملLaser injection of ultrashort electron pulses into Wakefield plasma waves.
A novel laser-plasma-based source of relativistic electrons is described. It involves a combination of orthogonally directed laser beams, which are focused in a plasma. One beam excites a wakefield electron plasma wave. Another locally alters the trajectory of some of the electrons in such a way that they can be accelerated and trapped by the wave. With currently available table-top terawatt la...
متن کاملAn electron–positron beam–plasma instability
Using a new technique to generate cold electron beams, an electron-beam positron-plasma experiment was performed in a previously unexplored range of energies. An electron beam, formed from a thermalized room-temperature electron plasma, is transmitted through a positron plasma stored in a quadrupole Penning trap geometry. The transit-time instability, which is excited by the beam, was previousl...
