Effect of transition layer on wakefield in plasma waveguide
Peter Markov, Kostyantyn Galaydych, Gennadiy Sotnikov
Using 2.5D particle-in-cell simulations, we investigate the parameters of a plasma wakefield accelerator (PWFA) for positrons and electrons in a layered plasma waveguide (LPW) in t…
Wakefield Acceleration in a Layered Plasma Waveguide
G. V. Sotnikov, K. V. Galaydych, P. I. Markov
Plasma wakefield accelerators (PWFA) represent one of the promising new accelerator concepts that are now being developed intensively for future applications in high-energy physics…
Theory of wakefield in a transversely inhomogeneous plasma waveguide
K. V. Galaydych, P. I. Markov, G. V. Sotnikov
Theoretical studies have been made into the relativistic drive bunch generation of a wakefield in a cylindrical waveguide filled with a transversely inhomogeneous plasma. According…
Acceleration and Focusing Electron/Positron Bunches in Plasma-Dielectric Wakefield Accelerator
Gennadiy V. Sotnikov, Kostyantyn V. Galaydych, Jay L. Hirshfield +2
To mitigate the BBU instability and improve characteristics of accelerated bunches in Dielectric Wakefield Accelerator one can be used the isotropic plasma filling of the transport…
Bunch-excited wakefield in dielectric waveguide with hollow plasma channel
K. V. Galaydych, P. I. Markov, G. V. Sotnikov
Wakefield excitation by a single relativistic electron bunch in a plasma-dielectric accelerating structure has been studied both analytically and numerically. The structure represe…
Theory of wakefields excited by an off-axis drive bunch in a plasma-dielectric waveguide
K. V. Galaydych, G. V. Sotnikov, I. N. Onishchenko
A linear theory of a wakefield excitation in a plasma-dielectric accelerating structure by a drive electron bunch in the case of an off-axis bunch injection has been constructed. T…
BBU instability in rectangular dielectric resonator
G. V. Sotnikov, K. V. Galaydych, R. R. Kniaziev +1
Studies were made into the arise and an evolution of the beam breakup (BBU) instability in a rectangular dielectric resonator under excitation by a sequence of relativistic electro…
Performance analysis of the prototype THz-driven electron gun for the AXSIS project
G. Vashchenko, R. Assmann, U. Dorda +9
The AXSIS project (Attosecond X-ray Science: Imaging and Spectroscopy) aims to develop a THz-driven compact X-ray source for applications e.g. in chemistry and biology by using ult…
Beam Dynamics and Tolerance Studies of the THz-driven Electron Linac for the AXSIS Experiment
K. Galaydych, R. Assmann, U. Dorda +3
A dielectric-loaded linac powered by THz-pulses is one of the key parts of the "Attosecond X-ray Science: Imaging and Spectroscopy" (AXSIS) project at DESY, Hamburg. As in conventi…
Status and Objectives of the Dedicated Accelerator R&D Facility "SINBAD" at DESY
U. Dorda, B. Marchetti, J. Zhu +12
We present a status update on the dedicated R\&D facility SINBAD which is currently under construction at DESY. The facility will host multiple independent experiments on the accel…
