PBPL Publications: 2007-00008 PUBLICATIONS OBSERVATIONS OF UNDERDENSE PLASMA LENS FOCUSING OF RELATIVISTIC ELECTRON BEAMS
Focusing of a 15 MeV, 19 nC electron bunch by an underdense plasma lens operated just beyond the threshold of the underdense condition has been demonstrated in experiments at the Fermilab NICADD Photoinjector Laboratory (FNPL). The strong 1.9 cm focal-length plasmalens focused both transverse directions simultaneously and reduced the minimum area of the beam spot by a factor of 23. Analysis of ...

متن کاملNumerical simulation of short laser pulse relativistic self-focusing in underdense plasma
Existing experimental results on relativistic self-focusing are interpreted by means of the particle code WAKE using the ponderomotive approximation to describe the laser–plasma interaction @P. Mora and T. M. Antonsen, Jr., Phys. Plasmas 4, 217 ~1997!#. Novel features of the code, such as gas medium ionization and an enhanced paraxial approximation, allow more confidence in data interpretation....
متن کاملTransverse dynamics of a relativistic electron beam in an underdense plasma channel
The transverse dynamics of a relativistic electron beam in a plasma less dense than the beam is analyzed, with particular attention to the electron-hose instability as it appears in a plasma channel of finite radius. A comparison is made between analytic asymptotic forms, linearized ‘‘beam break-up’’ simulations, and particle-in-cell simulations. The analysis provides a framework for the interp...
متن کاملFrequency Upshifting and Pulse Compression via Underdense Relativistic Ionization Fronts
When pulse of electromagnetic radiation impinges upon a moving plasmalneutral gas boundary, i.e., an ionization front, its frequency and duration are altered. The largest frequency upshifts and pulse compressions are obtained when radiation is incident on an ionization front moving at close to the speed of light. Such an ionization front is created when a short laser pulse photo-ionizes a gas t...
