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…
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…
Bright muon source driven by GeV electron beams from a compact laser wakefield accelerator
Bobbili Sanyasi Rao, Jong Ho Jeon, Hyung Taek Kim +1
We report here a systematic quantitative study on generation and characteristics of an active muon source driven by the interaction of an electron beam within the energy range of 1…
