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…
Instantaneous ionization rate as a functional derivative
I. A. Ivanov, C. Hofmann, L. Ortmann +3
We describe an approach defining instantaneous ionization rate (IIR) as a functional derivative of the total ionization probability. The definition is based on physical quantities…
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…
Laser acceleration of highly energetic carbon ions using a double-layer target composed of slightly underdense plasma and ultrathin foil
W. J. Ma, I Jong Kim, J. Q. Yu +18
We report the experimental generation of highly energetic carbon ions up to 48 MeV per nucleon by shooting double-layer targets composed of well-controlled slightly underdense plas…
