Spatial profile of accelerated electrons from ponderomotive scattering in hydrogen cluster targets
B. Aurand, L. Reichwein, K. M. Schwind +10
We study the laser-driven acceleration of electrons from overdense hydrogen clusters to energies of up to 13 MeV in laser forward direction and several hundreds of keV in an outer…
Fixing E-field divergence in strongly nonlinear wakefields in homogeneous plasma
Lars Reichwein, Johannes Thomas, Anton Golovanov +2
Available analytical wakefield models for the bubble and the blow-out regime of electron-plasma acceleration perfectly describe important features like shape, fields, trapping rati…
A spin-filter for polarized electron acceleration in plasma wakefields
Yitong Wu, Liangliang Ji, Xuesong Geng +7
We propose a filter method to generate electron beams of high polarization from bubble and blow-out wakefield accelerators. The mechanism is based on the idea to identify all elect…
Finite-emittance Wigner crystals in the bubble regime
Lars Reichwein, Johannes Thomas, Alexander Pukhov
We study the influence of finite emittance electron bunches in the bubble regime of laser-driven wakefield acceleration onto the microscopic structure of the bunch itself. Using re…
Scaling laws for the (de-)polarization time of relativistic particle beams in strong fields
Johannes Thomas, Anna Hützen, Andreas Lehrach +5
The acceleration of polarized electrons and protons in strong laser and plasma fields is a very attractive option to obtain polarized beams in the GeV range. We investigate the fea…
Spin polarized proton beam generation from gas-jet targets by intense laser pulses
Luling Jin, Meng Wen, Xiaomei Zhang +4
A method of generating spin polarized proton beams from a gas jet by using a multi-petawatt laser is put forward. With currently available techniques of producing pre-polarized mon…
Polarized electron-beam acceleration driven by vortex laser pulses
Yitong Wu, Liangliang Ji, Xuesong Geng +15
We propose a new approach based on an all-optical set-up for generating relativistic polarized electron beams via vortex Laguerre-Gaussian (LG) laser-driven wakefield acceleration.…
The filamented electron bunch of the bubble regime
Lars Reichwein, Johannes Thomas, Alexander Pukhov
We present a theory for describing the inner structure of the electron bunch in the bubble regime starting from a random distribution of electrons inside the bubble and subsequentl…
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…
Study of external electron injection and trapping in the blow-out regime
Jari Pronold, Johannes Thomas, Alexander Pukhov
In this work we study electron side-injection and trapping in the blow-out regime in deep plasma channels. We analyze the maximum angle of injection, for which at least 90\% of the…
2D structures of electron bunches in relativistic plasma cavities
Lars Reichwein, Johannes Thomas, Alexander Pukhov
The spatial structure of an ultra-low emittance electron bunch in a plasma wakefield blowout regime is studied. The full Liénard-Wiechert potentials are considered for mutual inter…
Analytic model for electromagnetic fields in the bubble regime of plasma wakefield in non-uniform plasmas
A. A. Golovanov, I. Yu. Kostyukov, J. Thomas +1
Based on a model of plasma wakefield in the strongly nonlinear (bubble) regime, we develop a lowest-order perturbation theory for the components of electromagnetic fields inside an…
Beam loading in the bubble regime in plasmas with hollow channels
A. A. Golovanov, I. Yu. Kostyukov, J. Thomas +1
Based on the already existing analytical theory of the strongly-nonlinear wakefield (which is called "bubble") in transversely inhomogeneous plasmas, we study particular behavior o…
A non-linear theory for the bubble regime of plasma wake fields in tailored plasma channels
Johannes Thomas, Igor Yu. Kostyukov, Jari Pronold +2
We introduce a first full analytical bubble and blow-out model for a radially inhomogeneous plasma in a quasi-static approximation. For both cases we calculate the accelerating and…
Field-reversed bubble in deep plasma channels for high quality electron acceleration
A. Pukhov, O. Jansen, T. Tueckmantel +2
We study hollow plasma channels with smooth boundaries for laser-driven electron acceleration in the bubble regime. Contrary to the uniform plasma case, the laser forms no optical…
Relativistic electron Wigner crystal formation in a cavity for electron acceleration
Johannes Thomas, Marc M. Günther, Alexander Pukhov
It is known that a gas of electrons in a uniform neutralizing background can crystallize and form a lattice if the electron density is less than a critical value. This crystallizat…
Temporal and spatial expansion of a multidimensional model for electron acceleration in the bubble regime
Johannes Thomas, Alexander Pukhov
An extended analytical model for particle dynamics in fields of a highly-nonlinear plasma wake field (the bubble or blow out regime) is derived. A recently proposed piecewise model…
