Plasma-based accelerators that impart energy gain as high as several GeV to electrons or
positrons within a few centimeters have engendered a new class of diagnostic techniques …

Compact, tunable, radially symmetric focusing of electrons is critical to laser-plasma
accelerator (LPA) applications. Experiments are presented demonstrating the use of a …

This article first gives the authors' perspectives on how the field of plasma-based
acceleration (PBA) developed and how the current experiments, theory, and simulations are …

Using quadrupole scan measurements we show laser-wakefield accelerated electrons to
have a normalized transverse emittance of 0.21-0.02+ 0.01 π mm mrad at 245 MeV. We …

Laser-based electron sources are attracting strong interest from the conventional accelerator
community due to their unique characteristics in terms of high initial energy, low emittance …

Narrow bandwidth, high energy photon sources can be generated by Thomson scattering of
laser light from energetic electrons, and detailed control of the interaction is needed to …

Active plasma lenses have attracted interest in novel accelerator applications due to their
ability to provide large-field-gradient (short focal length), tunable, and radially symmetric …

Recent experiments with 100 terawatt-class, sub-50 femtosecond laser pulses show that
electrons self-injected into a laser-driven electron density bubble can be accelerated above …

Few-fs electron bunches from laser wakefield acceleration (LWFA) can efficiently drive
plasma wakefields (PWFs), as shown by their propagation through underdense plasma in …

Underdense plasma produced in gas jets by low intensity laser prepulses in the presence of
a static magnetic field, B∼ 0.3 T, is shown experimentally to become an optical element …
