Features of long particle beam self-modulated in plasma
Vlada Yarygova, Konstantin Lotov
Under certain conditions, a long particle beam self-modulates in a dense plasma, that is, it breaks down into a train of short, stable microbunches under the influence of its own w…
Oscillation damper for misaligned witness in plasma wakefield accelerator
K. V. Lotov, I. Yu. Kargapolov, P. V. Tuev
If a laser- or particle beam-driven plasma wakefield accelerator operates in the linear or moderately nonlinear regime, injecting an externally produced particle bunch (witness) to…
Advanced quasistatic approximation
P. V. Tuev, R. I. Spitsyn, K. V. Lotov
The quasistatic approximation (QSA) is an efficient method of simulating laser- and beam-driven plasma wakefield acceleration, but it becomes imprecise if some plasma particles mak…
Attenuation of waveguide modes in narrow metal capillaries
P. V. Tuev, K. V. Lotov
The channeling of laser pulses in waveguides filled with a rare plasma is one of promising techniques of laser wakefield acceleration. A solid-state capillary can precisely guide t…
Accelerating field enhancement due to ion motion in plasma wakefield accelerators
V. A. Minakov, A. P. Sosedkin, K. V. Lotov
Ion motion in plasma wakefield accelerators can cause temporal increase of the longitudinal electric field shortly before the wave breaks. The increase is caused by re-distribution…
Amplitude enhancement of the self-modulated plasma wakefields
Y. Li, G. Xia, K. V. Lotov +3
Seeded Self-modulation (SSM) has been demonstrated to transform a long proton bunch into many equidistant micro-bunches (e.g., the AWAKE case), which then resonantly excite strong…
AWAKE, The Advanced Proton Driven Plasma Wakefield Acceleration Experiment at CERN
E. Gschwendtner, E. Adli, L. Amorim +88
The Advanced Proton Driven Plasma Wakefield Acceleration Experiment (AWAKE) aims at studying plasma wakefield generation and electron acceleration driven by proton bunches. It is a…
Path to AWAKE: Evolution of the concept
A. Caldwell, E. Adli, L. Amorim +118
This report describes the conceptual steps in reaching the design of the AWAKE experiment currently under construction at CERN. We start with an introduction to plasma wakefield ac…
Guiding femtosecond high-intensity high-contrast laser pulses by copper capillaries
V. E. Leshchenko, K. V. Gubin, V. I. Trunov +2
Propagation of high-intensity, high-contrast (), 50\,fs laser pulses through triangilar copper capillaries is experimentally studied. The relative transmission through 20…
Parameter sensitivity of plasma wakefields driven by self-modulating proton beams
K. V. Lotov, V. A. Minakov, A. P. Sosedkin
The dependence of wakefield amplitude and phase on beam and plasma parameters is studied in the parameter area of interest for self-modulating proton beam-driven plasma wakefield a…
Long-term evolution of broken wakefields in finite radius plasmas
Konstantin Lotov, Alexander Sosedkin, Alexey Petrenko
A novel effect of fast heating and charging a finite-radius plasma is discovered in the context of plasma wakefield acceleration. As the plasma wave breaks, the most of its energy…
Proton-driven plasma wakefield acceleration: a path to the future of high-energy particle physics
AWAKE Collaboration, R. Assmann, R. Bingham +47
New acceleration technology is mandatory for the future elucidation of fundamental particles and their interactions. A promising approach is to exploit the properties of plasmas. P…
Natural noise and external wake field seeding in a proton-driven plasma accelerator
K. V. Lotov, G. Z. Lotova, V. I. Lotov +4
We discuss the level of natural shot noise in a proton bunch-driven plasma accelerator. The required seeding for the plasma wake field must be larger than the cumulative shot noise…
