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.…
