“…Alignment between proton and laser beams (and thus plasma) is obtained and maintained using beam position monitors and a virtual laser line. The SSM process develops along the plasma with saturation expected before its end [24]. At saturation the microbunches are fully formed and propagate towards the plasma end and diagnostics.…”

We give direct experimental evidence for the observation of the full transverse self-modulation of a long, relativistic proton bunch propagating through a dense plasma. The bunch exits the plasma with a periodic density modulation resulting from radial wakefield effects. We show that the modulation is seeded by a relativistic ionization front created using an intense laser pulse copropagating with the proton

“…Extensive recent studies and computer simulations have indicated that a high energy proton bunch is capable of exciting strong electromagnetic wakefields in a plasma which can accelerate a bunch of electrons to the energy frontier of up to a TeV in energy in a single stage of acceleration [8], [9]. If proton beams from existing high energy proton colliders e.g.…”

“…It will be implemented in the SPS beam extraction cave area originally used for generating neutrinos via a high power target for the Gran Sasso experiment. A pan-European collaboration has been formed for a few years now [9] and commissioning is just beginning. The current AWAKE time line involves initial running in 2016 for 4 weeks equivalent of continuous running with proton-beam commissioning, a Phase 1 of initial data-taking and a Phase 2 of further fabrication and installation of the plasma column and electron injector during calendar years 2017 and 2018, followed by a Long Shutdown for 24 months during calendar years 2019 and 2020, followed by serious systematic wakefield Acceleration studies.…”

An overview is provided of the currently envisaged landscape of charged particle accelerators at the energy and intensity frontiers to explore particle physics beyond the standard model via 1-100 TeV-scale lepton and hadron colliders and multi-Megawatt proton accelerators for short-and longbaseline neutrino experiments. The particle beam physics, associated technological challenges and progress to date for these accelerator facilities (LHC, HL-LHC, future 100 TeV p-p colliders, Tev-scale linear and circular electron-positron colliders, high intensity proton accelerator complex PIP-II for DUNE and future upgrade to PIP-III) are outlined. Potential and prospects for advanced "nonlinear dynamic techniques" at the multi-MW level intensity frontier and advanced "plasmawakefield-based techniques" at the TeV-scale energy frontier and are also described.

“…A very similar problem arose recently in the context of the Advanced Proton Driven Plasma Wakefield Acceleration Experiment (AWAKE) experiment at CERN. AWAKE is a proton-driven plasma wakefield acceleration experiment, the first of its kind, which uses high-energy proton bunches to drive wakefields in a plasma for electron acceleration [6][7][8]. Central to the device is a 10 m long rubidium vapor cell where the proton bunch interacts with the plasma serving as an energy exchange medium between the protons and the injected electrons.…”

Propagation of ultrashort resonant ionizing laser pulses in rubidium vapor

We investigate the propagation of ultra-short laser pulses in atomic rubidium vapor. The pulses are intensive enough to ionize the atoms and are directly resonant with the 780 nm D2 line. We derive a relatively simple theory for computing the nonlinear optical response of atoms and investigate the competing effects of strong resonant nonlinearity and ionization in the medium using computer simulations. A nonlinear self-channeling of pulse energy is found to produce a continuous plasma channel with complete ionization. We evaluate the length, width and homogeneity of the resulting plasma channel for various values of pulse energy and initial focusing to identify regimes optimal for applications in plasma-wave accelerator devices such as that being built by the AWAKE collaboration at CERN. Similarities and differences with laser pulse filamentation in atmospheric gases are discussed.
