Collisionless shock acceleration of narrow energy spread ion beams from mixed species plasmas using 1 m lasers
A. Pak, S. Kerr, N. Lemos +15
Collisionless shock acceleration of protons and C ions has been achieved by the interaction of a 10 W/cm, 1 m laser with a near-critical density plasma. Ablat…
Laser-driven Collisionless Shock Acceleration of Ions from Near-critical plasmas
S. Tochitsky, A. Pak, F. Fiuza +5
This paper overviews experimental and numerical results on acceleration of narrow energy spread ion beams by an electrostatic collisionless shockwave driven by 1 um (Omega EP) and…
Two-loop QCD corrections to semileptonic b-quark decays near maximum recoil
A. Pak, I. Blokland, A. Czarnecki
Two-gluon radiative corrections to the decay width have been computed analytically as an expansion in terms of \frac{m_c}{m_b} << 1 in the kinematical limit of zero…
Monte-Carlo Simulation of Exclusive Channels in e+e- Annihilation at Low Energy
D. Anipko, S. Eidelman, A. Pak
Software package for Monte-Carlo simulation of e+e- exclusive annihilation channels written in the C++ language for Linux/Solaris platforms has been developed. It incorporates matr…
Experiments conducted in the burning plasma regime with inertial fusion implosions
J. S. Ross, J. E. Ralph, A. B. Zylstra +149
An experimental program is currently underway at the National Ignition Facility (NIF) to compress deuterium and tritium (DT) fuel to densities and temperatures sufficient to achiev…
Predominant Contribution of Direct Laser Acceleration to High-Energy Electron Spectra in a Low-Density Self-Modulated Laser Wakefield Accelerator
P. M. King, K. Miller, N. Lemos +12
The two-temperature relativistic electron spectrum from a low-density (~cm) self-modulated laser wakefield accelerator (SM-LWFA) is observed to transition be…
