The accelerating gradient from such a plasma wakefield is much higher than can be achieved in conventional radio-frequency-based technology. 2015 May 8;114(18):184801. doi: 10.1103/PhysRevLett.114.184801.
The resulting microbunches can accelerate electrons injected into the stream.Wakefield acceleration can use different drivers.
In the laser-driven case (top), a strong laser pulse is fired into a preformed plasma.

/Resources <> There are basically two ways out of this so-called dephasing issue: either one stages several laser-driven plasma accelerator units in succession, or one selects a different driver—a high-energy proton bunch that moves through the plasma at near the speed of light. /Filter /FlateDecode
<< The pulse induces charge separation in the plasma, and the electric field from this charge configuration can accelerate trapped electrons.

/ProcSet [/PDF/Text/ImageB/ImageC/ImageI] One way to accelerate particles is to fire an intense laser pulse into a plasma, creating a density wake whose electric field pushes charged particles like electrons to high speeds [ 1 ].

It is still not clear when the “moon landing” will happen in the form of a wakefield-accelerator user facility. The alternative approach is to use a single high-energy proton bunch as a driver. stream J. Gonsalves, K. Nakamura, J. Daniels, C. Benedetti, C. Pieronek, T. C. H. de Raadt, S. Steinke, J. H. Bin, S. S. Bulanov, J. van Tilborg, C. G. R. Geddes, C. B. Schroeder, Cs. A method for accelerating particles, called wakefield acceleration, has notched up its output energy, bringing it closer to its goal of shrinking the size of accelerator facilities. endstream %PDF-1.6

The first-generation laser-plasma experiments operated with just one laser, which both created the plasma (through gas ionization) and generated the wakefield. Abstract This review article highlights the recent evolution of research on laser wakefield accelerators, which has, in record time, led to the production of high quality electron beams beyond the GeV level, using compact laser systems. �q��9�����Mܗ8%����CMq.�5�S�hr����A���I���皎��\S���ȩ����]8�`Y�7ь1O�ye���zl��,dmYĸ�S�SJf�-�1i�:C&e c4�R�������$D&�� Usually achieved in matter, superluminal propagation has also been demonstrated in vacuum with quasi-Bessel beams6,7 or spatio-temporal couplings8,9.
