“…As a consequence, the normalized emittance of the beam may grow due to the betatron oscillation (BO) and finally saturate [10], with the saturation normalized emittance commonly ranging from 0.1 to 100 mm•mrad, depending on the injection mechanism, e.g. self-injection, density gradient injection, optical injection, ionization injection and so on [11][12][13][14][15][16][17][18][19][20].…”

A classical model of radiation reaction for the betatron oscillation of an electron in a plasma wakefield accelerator is presented. The maximum energy of the electron due to the longitudinal radiation reaction is found, and the betatron oscillation damping due to both the longitudinal and transverse radiation reaction effects is analyzed. Both theoretical and numerical solutions are shown with good agreements. The regime that the quantum radiation takes effect is also discussed. This model is important for designing future plasma based super accelerators or colliders.

“…The electron emission time was observed to have a dependence on the plasma density. Relatively controllable injection mechanisms such as ionization injection, down-ramp injection with a steep profile, or colliding pulse injection [62][63][64] should be applied to get electron bunches with minimum jitter for various applications. This investigation could be helpful for the application of the EO sampling method as a real-time timing monitor for LWFA experiments and related ultrafast pump-probe studies.…”

As an advanced accelerator concept, laser wakefield acceleration, with its attractive acceleration gradient, has invoked great interest worldwide. The electron beams from laser wakefield acceleration were assumed to have the advantage of "jitterfree" or relatively small jitter, since the emergence of quasimonoenergetic bunch structures were considered to result from the trapping of electrons into the first bucket of the plasma wave. However, the emission times of the electron bunches from laser wakefield acceleration have not been real time monitored in experiments up to now. To examine this, we introduced the electro-optic spatial decoding method. The relative emission times of the electrons were observed to have variations with different plasma densities when using a laser with moderate intensity. The study shows that timing issues should not be ignored in some occasions of laser wakefield acceleration. The method used in this paper could be a candidate serving as a single-shot nondestructive electron bunch timing monitor for laser wakefield experiment and potential ultrafast pump-probe studies.

“…In this work, we present a novel all-optical approach to the generation of ultrashort electron bunch trains in a laser-driven wakefield via the recently-demonstrated injection mechanisms of ponderomotive drift, wake-wake interference, and laser field pre-ionization 26 . We launch two high-intensity laser pulses, drive and injector pulses, and overlap them in plasma at a steep angle.…”

We demonstrate a novel approach to the generation of femtosecond electron bunch trains via laserdriven wakefield acceleration. We use two independent high-intensity laser pulses, a drive, and injector, each creating their own plasma wakes. The interaction of the laser pulses and their wakes results in a periodic injection of free electrons in the drive plasma wake via several mechanisms, including ponderomotive drift, wake-wake interference, and pre-acceleration of electrons directly by strong laser fields. Electron trains were generated with up to 4 quasi-monoenergetic bunches, each separated in time by a plasma period. The time profile of the generated trains is deduced from an analysis of beam loading and confirmed using 2D Particle-in-Cell simulations.
