High-energy betatron source driven by a 4-PW laser with applications to non-destructive imaging
Calin Ioan Hojbota, Mohammad Mirzaie, Do Yeon Kim +10
Petawatt-class lasers can produce multi-GeV electron beams through laser wakefield electron acceleration. As a by-product, the accelerated electron beams can generate broad synchro…
Optical Shaping of Plasma Cavity for Controlled Laser Wakefield Acceleration
Bobbili Sanyasi Rao, Myung Hoon Cho, Hyung Taek Kim +7
Laser wakefield accelerators rely on relativistically moving micron-sized plasma cavities that provide extremely high electric field >100GV/m. Here, we demonstrate transverse shapi…
Accurate single-shot measurement technique for the spectral distribution of GeV electron beams from a laser wakefield accelerator
Calin Ioan Hojbota, Hyung Taek Kim, Jung Hun Shin +3
We present a technique, based on a dipole magnet spectrometer containing multiple scintillation screens, to accurately characterize the spectral distribution of a GeV electron beam…
Proof-of-principle experiment for nanoparticle-assisted laser wakefield acceleration
Constantin Aniculaesei, Vishwa Bandhu Pathak, Kyung Hwan Oh +9
In the present work, we demonstrate for the first time a proof-of-principle experiment for nanoparticle-assisted laser wakefield acceleration. The nanoparticles, generated through…
Entropy-based view of the strong field ionization process
I. A. Ivanov, Chang Hee Nam, Kyung Taec Kim
We apply information theoretic entropies of coordinate and velocity distributions in quantum mechanics for the description of the strong field ionization process. The approach is b…
Electron energy increase in a laser wakefield accelerator using longitudinally shaped plasma density profiles
Constantin Aniculaesei, Vishwa Bandhu Pathak, Hyung Taek Kim +13
The phase velocity of the wakefield of a laser wakefield accelerator can, theoretically, be manipulated by shaping the longitudinal plasma density profile, thus controlling the par…
