Intense lasers can accelerate electrons to very high energy over a short distance. Such compact accelerators have several potential applications including fast ignition, high energy physics, and radiography. Among the various schemes of laser-based electron acceleration, vacuum laser acceleration has the merits of super-high acceleration gradient and great simplicity. Yet its realization has been difficult because injecting free electrons into the fast-oscillating laser field is not trivial. Here we demonstrate free-electron injection and subsequent vacuum laser acceleration of electrons up to 20 MeV using the relativistic transparency effect. When a high-contrast intense laser drives a thin solid foil, electrons from the dense opaque plasma are first accelerated to near-light speed by the standing laser wave in front of the solid foil and subsequently injected into the transmitted laser field as the opaque plasma becomes relativistically transparent. It is possible to further optimize the electron injection/acceleration by manipulating the laser polarization, incident angle, and temporal pulse shaping. Our result also sheds light on the fundamental relativistic transparency process, crucial for producing secondary particle and light sources.

“…Here, f , N , σ x , σ y are the repetition rate of colliding bunches, single bunch population and rms beam sizes at the interaction point in x and y directions respectively. A collider that is built for the precision measurements of the Higgs boson will require center-of-mass e − /e + beam energy of about 250GeV and L ∼ 10 34 cm −2 s −1 , that can be achieved by 10 10 particles per bunch with a collision rate 1kHz and σ x σ y < 8000nm 2 [13]. To tightly final focus the beam usually requires high beam quality, such as the beam energy spread much less than 1%.…”

We propose a novel positron beam loading regime in a hollow plasma channel that can efficiently accelerate e + beam with high gradient and narrow energy spread. In this regime, the e + beam coincides with the drive e − beam in time and space and their net current distribution determines the plasma wakefields. By precisely shaping the beam current profile and loading phase according to explicit expressions, three-dimensional Particle-in-Cell (PIC) simulations show that the acceleration for e + beam of ∼nC charge with ∼GV/m gradient, 0.5% induced energy spread and ∼50% energy transfer efficiency can be achieved simultaneously. Besides, only tailoring the current profile of the more tunable e − beam instead of the e + beam is enough to obtain such favorable results. A theoretical analysis considering both linear and nonlinear plasma responses in hollow plasma channels is proposed to quantify the beam loading effects. This theory agrees very well with the simulation results and verifies the robustness of this beam loading regime over a wide range of parameters.

“…The development of LPAs has seen remarkable progress in recent years [9][10][11]. Micrometer-sized electron bunches with GeV-scale energies can be generated from LPA stages a few centimetres long [12][13][14][15][16], and hence LPAs have the potential to drive highly compact sources of high-energy, femtosecond-duration particles and radiation [17][18][19][20][21][22][23].…”

Gev-Scale Accelerators Driven by Plasma-Modulated Pulses from Kilohertz Lasers

We describe a new approach for driving GeV-scale plasma accelerators with long laser pulses. We show that the temporal phase of a long, high-energy driving laser pulse can be modulated periodically by co-propagating it with a low-amplitude plasma wave driven by a short, low-energy seed pulse. Compression of the modulated driver by a dispersive optic generates a train of short pulses suitable for resonantly driving a plasma accelerator. Modulation of the driver occurs via well-controlled linear processes, as confirmed by good agreement between particle-in-cell (PIC) simulations and an analytic model. PIC simulations demonstrate that a 1.7 J, 1 ps driver and a 140 mJ, 40 fs seed pulse can accelerate electrons to energies of 0.65 GeV in a plasma channel with an axial density of 2.5 × 10 17 cm −3 . This work opens a route to high-repetition-rate, GeV-scale plasma accelerators driven by thin-disk lasers, which can provide joule-scale, picosecond-duration laser pulses at multikilohertz repetition rates and high wall-plug efficiencies.
