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)...

We measured $\frac{d\ensuremath{\sigma}}{\mathrm{dt}}$ for ${p}_{\ensuremath{\uparrow}}+{p}_{\ensuremath{\uparrow}}\ensuremath{\rightarrow}p+p$ from ${{P}_{\ensuremath{\perp}}}^{2}=4.50 \mathrm{to} 5.09$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$ at 11.75 GeV/c. used a 59%-polarized proton beam and 71%-polarized target with both spins oriented perpendicular to the scattering plane. In these large-${{P}_{\ensuremath{\perp}}}^{2}$ hard-scattering events, spin effects are very large...

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