Transition between Instability and Seeded Self-Modulation of a Relativistic Particle Bunch in Plasma
F. Batsch, P. Muggli, R. Agnello +94
We use a relativistic ionization front to provide various initial transverse wakefield amplitudes for the self-modulation of a long proton bunch in plasma. We show experimentally t…
Proton Bunch Self-Modulation in Plasma with Density Gradient
F. Braunmüller, T. Nechaeva, AWAKE Collboration
We study experimentally the effect of linear plasma density gradients on the self-modulation of a 400\,GeV proton bunch. Results show that a positive/negative gradient in/decreases…
Volumetric heating of nanowire arrays to keV temperatures using kilojoule-scale petawatt laser interactions
M. P. Hill, O. Humphries, R. Royle +19
We present picosecond-resolution streaked K-shell spectra from 400 nm-diameter nickel nanowire arrays, demonstrating the ability to generate large volumes of high energy density pl…
Polarized Proton Beams from Laser-induced Plasmas
Anna Hützen, Johannes Thomas, Jürgen Böker +7
We report on the concept of an innovative source to produce polarized proton/deuteron beams of a kinetic energy up to several GeV from a laser-driven plasma accelerator. Spin effec…
AWAKE readiness for the study of the seeded self-modulation of a 400\,GeV proton bunch
P. Muggli, E. Adli, R. Apsimon +104
AWAKE is a proton-driven plasma wakefield acceleration experiment. % We show that the experimental setup briefly described here is ready for systematic study of the seeded self-mod…
Nano-scale ultra-dense Z-pinches formation from laser-irradiated nanowire arrays
Vural Kaymak, Alexander Pukhov, Vyacheslav N. Shlyaptsev +1
We show that ulta-dense Z-pinches with nanoscale dimensions can be generated by irradiating aligned nanowires with femtosecond laser pulses of relativistic intensity. Using fully t…
Self-modulation instability of a long proton bunch in plasmas
Naveen Kumar, Alexander Pukhov, Konstantin Lotov
An analytical model for the self-modulation instability of a long relativistic proton bunch propagating in uniform plasmas is developed. The self-modulated proton bunch resonantly…
Stable laser-driven proton beam acceleration from a two-specie ultra-thin foil
T. P. Yu, A. Pukhov, G. Shvets +1
By using multi-dimensional particle-in-cell simulation, we present a new regime of stable proton beam acceleration which takes place when a two-specie shaped foil is illuminated by…
Radiation reaction effects on ion acceleration in laser foil interaction
Min Chen, Alexander Pukhov, Tong-Pu Yu +1
Radiation reaction effects on ion acceleration in laser foil interaction are investigated via analytical modeling and multi-dimensional particle-in-cell simulations. We find the ra…
Target shape effects on monoenergetic GeV proton acceleration
Min Chen, Tong-Pu Yu, Alexander Pukhov +1
When a circularly polarized laser pulse interacts with a foil target, there are three stages: pre-hole-boring, hole-boring and the light sail acceleration. We study the electron an…
