Journal ArticleDOI
Laser acceleration of quasi-monoenergetic MeV ion beams
Bjorn Hegelich,Brian J. Albright,J. A. Cobble,Kirk Flippo,Samuel A. Letzring,M. Paffett,H. Ruhl,H. Ruhl,Jörg Schreiber,Roland Schulze,Juan C. Fernández +10 more
TL;DR: Quasi-monoenergetic laser-driven C5+ ions with a vastly reduced energy spread are reported, which may enable significant advances in the development of compact MeV ion accelerators, new diagnostics, medical physics, inertial confinement fusion and fast ignition.
Journal ArticleDOI
Radiation-pressure acceleration of ion beams driven by circularly polarized laser pulses.
A. Henig,Sven Steinke,Matthias Schnürer,Thomas Sokollik,Rainer Hörlein,Daniel Kiefer,Daniel Jung,Jörg Schreiber,Bjorn Hegelich,X. Q. Yan,Jürgen Meyer-ter-Vehn,Toshiki Tajima,Peter V. Nickles,W. Sandner,D. Habs +14 more
TL;DR: Two-dimensional particle-in-cell simulations reveal that those C6+ ions are for the first time dominantly accelerated in a phase-stable way by the laser radiation pressure.
Journal ArticleDOI
Monoenergetic and GeV ion acceleration from the laser breakout afterburner using ultrathin targets
Lin Yin,Brian J. Albright,Bjorn Hegelich,Kevin J. Bowers,Kirk Flippo,Thomas J. T. Kwan,Juan C. Fernández +6 more
TL;DR: In this article, a new laser-driven ion acceleration mechanism using ultrathin targets has been identified from particle-in-cell simulations, which accelerates ions to much higher energies using laser intensities comparable to earlier target normal sheath acceleration (TNSA).
Journal ArticleDOI
Bright laser-driven neutron source based on the relativistic transparency of solids
Markus Roth,Markus Roth,Daniel Jung,Katerina Falk,N. Guler,O. Deppert,M. Devlin,Andrea Favalli,Juan C. Fernández,Donald C. Gautier,M. Geissel,R. C. Haight,Christopher E. Hamilton,Bjorn Hegelich,Randall P. Johnson,Frank E. Merrill,Gabriel Schaumann,Kurt F. Schoenberg,Marius Schollmeier,T. Shimada,Terry N. Taddeucci,J. L. Tybo,F. Wagner,Stephen A. Wender,Carl Wilde,G. A. Wurden +25 more
TL;DR: This work demonstrated an ion acceleration mechanism based on the concept of relativistic transparency and produced an intense beam of high energy deuterons directed into a Be converter to produce a forward peaked neutron flux with a record yield.
Journal ArticleDOI
GeV laser ion acceleration from ultrathin targets: The laser break-out afterburner
TL;DR: A new laser-driven ion acceleration mechanism has been identified using particle-in-cell (PIC) simulations as discussed by the authors, which enables the acceleration of carbon ions to greater than 2 GeV energy at a laser intensity of only 1021 W/cm2.
