High energy particle accelerators have been crucial in providing a deeper understanding of fundamental particles and the forces that govern their interactions. In order to increase or reduce size accelerator, new acceleration schemes need be developed. Plasma wakefield acceleration, which electrons plasma are excited, leading strong electric fields, is one such promising novel technique. Pioneering experiments shown an intense laser pulse electron bunch traversing plasma, drives fields 10s...
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 proof-of-principle R&D experiment CERN the world׳s first experiment. AWAKE will be installed in former CNGS facility uses 400 GeV/c beam bunches from SPS. experiments focus on self-modulation instability of long (rms ~12 cm) bunch plasma. These are planned for end 2016. Later, 2017/2018, low energy (~15 MeV)...
New acceleration technology is mandatory for the future elucidation of fundamental particles and their interactions. A promising approach to exploit properties plasmas. Past research has focused on creating large-amplitude plasma waves by injecting an intense laser pulse or electron bunch into plasma. However, maximum energy gain electrons accelerated in a single stage limited driver. Proton bunches are most drivers wakefields accelerate TeV scale stage. An experimental program at CERN—the...

By varying one order magnitude, we frequency scales expected dependence on density, i.e., it equal to...
The seeded self-modulation of a relativistic, charged particle bunch in plasma is shown to grow both along the and plasma, resulting transverse wakefield amplitudes that far exceed initial seed values.
Abstract The Gamma Factory (GF) is an ambitious proposal, currently explored within the CERN Physics Beyond Colliders program, for a source of photons with energies up to ≈400 MeV and photon fluxes (up ≈10 17 s −1 ) exceeding those available gamma sources by orders magnitude. high‐energy (secondary) are produced via resonant scattering primary laser highly relativistic partially‐stripped ions circulating in accelerator. secondary emitted narrow cone energy beam can be monochromatized, down...

Abstract The Gamma Factory initiative proposes to develop novel research tools at CERN by producing, accelerating, and storing highly relativistic, partially stripped ion beams in the SPS LHC storage rings. By exciting electronic degrees of freedom stored ions with lasers, high‐energy narrow‐band photon will be produced properly collimating secondary radiation that is peaked direction ions' propagation. Their intensities, up 10 17 photons per second, several orders magnitude higher than...
We present the scheme for a rubidium vapor source that is used as plasma in AWAKE wakefield acceleration experiment. The process requires number of stringent parameters plasma: electron density adjustable (1-10)$\times$10$^{14}$cm$^{-3}$ range, 0.25% relative uniformity, sharp ($<$10cm) ramps at each end, gradient from -3 to +10% over 10m, and %-level step near beginning column. show with analytical direct Simulation Monte Carlo results proposed should meet these requirements.

It is shown that co-linear injection of electrons or positrons into the wakefield self-modulating particle beam possible and ensures high energy gain. The witness must co-propagate with tail part driver, since plasma wave phase velocity there can exceed light velocity, which necessary for efficient acceleration. If many periods long, then trapped charge limited by loading effects. initial trapping better positrons, but at acceleration stage a considerable fraction lost from wave. For...

A novel effect of fast heating and charging a finite-radius plasma is discovered in the context wakefield acceleration. As wave breaks, most its energy transferred to electrons. The electrons gain substantial transverse momentum escape radially, which gives rise strong charge-separation electric field azimuthal magnetic around plasma. slowly varying structure preserved for hundreds periods contains (together with hot electrons) up 80% initial energy.

The AWAKE experiment installed CNGS facility profiting existing infrastructure where only minor modifications need foreseen....
The AWAKE experiment had a very successful Run 1 (2016-8), demonstrating proton-driven plasma wakefield acceleration for the first time, through observation of modulation long proton bunch into micro-bunches and electrons up to 2 GeV in 10 m plasma. aims (2021-4) are have high-charge bunches accelerated high energy, about GeV, maintaining beam quality showing that process is scalable. scheme therefore promising method accelerate energy over short distances so develop useable technology...
Presently available high-energy proton beams in circular accelerators carry enough momentum to accelerate high-intensity electron and positron the TeV energy scale over several hundred meters of plasma with a density about 1e15 1/cm^3. However, wavelength at this is 100-1000 times shorter than typical longitudinal size beam. Therefore self-modulation instability (SMI) long (~10 cm) beam should be used create train micro-bunches which would then drive wake resonantly. Changing profile offers...
We discuss the possibility of creating novel research tools by producing and storing highly relativistic beams ionised atoms in CERN accelerator complex, exciting their atomic degrees freedom with lasers to produce high-energy photon beams.Intensity such would be several orders magnitude higher than offered presently operating light sources, particularly interesting γ-ray energy domain 0.1-400 MeV.In this range, high-intensity can used secondary polarised electrons, positrons, muons,...

The AWAKE Collaboration has been formed in order to demonstrate proton-driven plasma wakefield acceleration for the first time. This technique could lead future colliders of high energy but a much reduced length when compared proposed linear accelerators. CERN SPS proton beam CNGS facility will be injected into 10 m cell where long bunches modulated significantly shorter micro-bunches. These micro-bunches then initiate strong with peak fields above 1 GV/m that harnessed accelerate bunch...
