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…
Novel gas target for Laser Wakefield Accelerators
Constantin Aniculaesei, Hyung Taek Kim, Byeong Ju Yoo +2
A novel gas target for interactions between high power lasers and gaseous medium, especially for laser wakefield accelerators, has been designed, manufactured and characterized. Th…
New frontier of laser particle acceleration: driving protons to 93 MeV by radiation pressure
I Jong Kim, Ki Hong Pae, Chul Min Kim +10
The radiation pressure acceleration (RPA) of charged particles has been considered a challenging task in laser particle acceleration. Laser-driven proton/ion acceleration has attra…
Enhancement of electron energy to multi-GeV regime by a dual-stage laser-wakefield accelerator pumped by petawatt laser pulses
Hyung Taek Kim, Ki Hong Pae, Hyuk Jin Cha +6
Laser wakefield acceleration offers the promise of a compact electron accelerator for generating a multi-GeV electron beam using the huge field gradient induced by an intense laser…
Towards radiation pressure acceleration of protons using linearly polarized ultrashort petawatt laser pulses
I Jong Kim, Ki Hong Pae, Chul Min Kim +10
Particle acceleration using ultraintense, ultrashort laser pulses is one of the most attractive topics in relativistic laser-plasma research. We report proton/ion acceleration in t…
