“…More recently, the concept of Xray driven wakefield acceleration in solids has been studied by Zhang et al, 5 with 2D Particle-In-Cell (PIC) simulations of wakefields driven by X-rays of k ¼ 1 nm and moderate relativistic amplitudes a 0 $ 1-10. In this regime, they concluded good scalability of the accelerating structures, but with more prominent radiation reaction due to the enhancement of the quantum parameter v ¼ cE ?…”

“…On the other hand, inferring from scaling relations, for wavelengths in the X-ray regime, solid materials provide an avenue toward a new generation of even more compact wakefield accelerators-with TeV/cm gradients and ultrashort electron and photon beams, with reduced beam size and emittance. 5 As we will show, the short wavelength enhances the quantum parameter v. This could lead to a highly efficient radiation source of high energy photons even at moderate relativistic amplitudes a 0 ¼ eE=m e cx, where c is the speed of light and E is the electromagnetic field strength.…”

Advances in the generation of relativistic intensity pulses with wavelengths in the X-ray regime, through high harmonic generation from near-critical plasmas, open up the possibility of X-ray driven wakefield acceleration. The similarity scaling laws for laser plasma interaction suggest that X-rays can drive wakefields in solid materials providing TeV/cm gradients, resulting in electron and photon beams of extremely short duration. However, the wavelength reduction enhances the quantum parameter χ, hence opening the question of the role of non-scalable physics, e.g., the effects of radiation reaction. Using three dimensional Particle-In-Cell simulations incorporating QED effects, we show that for the wavelength λ=5 nm and relativistic amplitudes a0=10–100, similarity scaling holds to a high degree, combined with χ∼1 operation already at moderate a0∼50, leading to photon emissions with energies comparable to the electron energies. Contrasting to the generation of photons with high energies, the reduced frequency of photon emission at X-ray wavelengths (compared with that at optical wavelengths) leads to a reduction in the amount of energy that is removed from the electron population through radiation reaction. Furthermore, as the emission frequency approaches the laser frequency, the importance of radiation reaction trapping as a depletion mechanism is reduced, compared with that at optical wavelengths for a0 leading to similar χ.

“…Two-dimensional particle-in-cell simulations show that an acceleration gradient of TeV/cm is attainable, which is about three orders of magnitude higher than that of the normal plasma-based wakefield accelerations in lowdensity plasma. In addition to particle acceleration, the scheme can also produce high energy photons at tens of MeV (Zhang et al 2016b).…”

The presentations on laser plasma physics at the first AAPPS-DPP conference covered topics of inertial confined fusion physics and technologies, laboratory astrophysics and high-energy density physics, laser plasma-based particle acceleration (electrons and ions) and radiation, fundamental laser plasma physics, and related high-power laser system development. This report summarizes the major advances in these topics presented at the plenary and oral sessions.

“…Instead, wakefields driven by optical lasers conventionally use gaseous targets of lower density. On the other hand, inferring from scaling relations, for wavelengths in the X-ray regime, solid materials provide an avenue towards a new generation of even more compact wakefield accelerators -with TeV/cm gradients and ultra short electron and photon beams, with reduced beam size and emittance 5 .

“…Early work utilizing X-rays to drive slowwave accelerating structures in metallic crystal channels was conducted by Tajima et al 12 in the 1980s. More recently the concept of X-ray driven wakefield acceleration in solids has been revived by Zhang et al 5 , with 2D Particle-In-Cell simulations of wakefields driven by X-rays of λ = 1 nm and moderate relativistic amplitudes a 0 ∼ 1-10. In this regime, they concluded good scalability of the accelerating structures, but with more prominent radiation reaction due to the enhancement of the quantum parameter χ = γE ⊥ /E c , which governs the probability distribution and rate for photon emission.…”

Abstract: In Table I on page 3 and Table II on page 5 in the paper, the unit of plasma density n tube should be =cm 3 instead of W=cm 3 , and the tube radius σ tube should be 2.5 nm ðμmÞ instead of 2.5 nm ðμmÞ=0 nm ðμmÞ. Conclusions are not effected by this change.
