Beam current from downramp injection in electron-driven plasma wakefields
Céline Hue, Anton Golovanov, Sheroy Tata +2
We study the stability of plasma wake wave and the properties of density-downramp injection in an electron-driven plasma accelerator. In this accelerator type, a short high-current…
Positron acceleration via laser-augmented blowouts in two-column plasma structures
Lars Reichwein, Anton Golovanov, Igor Yu. Kostyukov +1
We propose a setup for positron acceleration consisting of an electron driver and a laser pulse creating a two-fold plasma column structure. The resulting wakefield is capable of a…
Radiation reaction-dominated regime of wakefield acceleration
A. A. Golovanov, E. N. Nerush, I. Yu. Kostyukov
We study electron acceleration in a plasma wakefield under the influence of the radiation-reaction force caused by the transverse betatron oscillations of the electron in the wakef…
Efficient narrowband teraherz radiation from electrostatic wakefields in non-uniform plasmas
Alexander Pukhov, Anton Golovanov, Igor Kostyukov
Abstract It is shown that electrostatic plasma wakefields can efficiently radiate at harmonics of the plasma frequency when the plasma has a positive density gradient along the pro…
Excitation of strongly nonlinear plasma wakefield by electron bunches
A. A. Golovanov, I. Yu. Kostyukov, L. Reichwein +2
We propose a new method for analytical self-consistent description of the excitation of a strongly nonlinear wakefield (a bubble) excited by an electron bunch. This method makes it…
Field ionization rate for PIC codes
I. Yu. Kostyukov, A. A. Golovanov
An improved formula is proposed for field ionization rate covering tunnel and barrier suppression regime. In contrast to the previous formula obtained recently in [I. Yu. Kostyukov…
Field ionization in short and extremely intense laser pulses
I. Yu. Kostyukov, A. A. Golovanov
Modern laser systems are able to generate short and intense laser pulses ionizing matter in the poorly explored barrier-suppression regime. Field ionization in this regime is studi…
Bubble regime of plasma wakefield in 2D and 3D geometries
A. A. Golovanov, I. Yu. Kostyukov
Considering the popularity of two-dimensional particle-in-cell simulations, a 2D model of plasma wakefield in the strongly nonlinear (bubble) regime in transversely non-uniform pla…
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…
