Demonstration of a 10-metre-long discharge plasma source for plasma wakefield acceleration
C. Amoedo, N. Lopes, N. E. Torrado +13
The AWAKE experiment at CERN uses high-energy proton bunches to drive plasma wakefields capable of accelerating electron bunches up to hundreds of GeV in a single plasma. Realising…
Experimental Observation of Motion of Ions in a Resonantly Driven Plasma Wakefield Accelerator
M. Turner, E. Walter, C. Amoedo +15
We show experimentally that an effect of motion of ions, observed in a plasma-based accelerator, depends inversely on the plasma ion mass. The effect appears within a single wakefi…
Filamentation of a Relativistic Proton Bunch in Plasma
L. Verra, C. Amoedo, N. Torrado +12
We show in experiments that a long, underdense, relativistic proton bunch propagating in plasma undergoes the oblique instability, that we observe as filamentation. We determine a…
Hosing of a long relativistic particle bunch in plasma
T. Nechaeva, L. Verra, J. Pucek +4
Experimental results show that hosing of a long particle bunch in plasma can be induced by wakefields driven by a short, misaligned preceding bunch. Hosing develops in the plane of…
Development of the Self-Modulation Instability of a Relativistic Proton Bunch in Plasma
L. Verra, S. Wyler, T. Nechaeva +7
Self-modulation is a beam-plasma instability that is useful to drive large-amplitude wakefields with bunches much longer than the plasma skin depth. We present experimental results…

M. Turner, S. S. Bulanov, C. Benedetti +7
The Petawatt (PW) laser facility of the Berkeley Lab Laser Accelerator (BELLA) Center has recently commissioned its second laser pulse transport line. This new beamline can be oper…
Report of the Snowmass 2021 Collider Implementation Task Force
Thomas Roser, Reinhard Brinkmann, Sarah Cousineau +12
The Snowmass 2021 Implementation Task Force has been established to evaluate the proposed future accelerator projects for performance, technology readiness, schedule, cost, and env…
Mapping charge capture and acceleration in a plasma wakefield of a proton bunch using variable emittance electron beam injection
E. Granados, L. Verra, A. -M. Bachmann +10
In the Phase 2 of the AWAKE first experimental run (from May to November 2018), an electron beam was used to probe and test proton-driven wakefield acceleration in a rubidium plasm…
The AWAKE Run 2 programme and beyond
Edda Gschwendtner, Konstantin Lotov, Patric Muggli +99
Plasma wakefield acceleration is a promising technology to reduce the size of particle accelerators. Use of high energy protons to drive wakefields in plasma has been demonstrated…
Whitepaper submitted to Snowmass21: Advanced accelerator linear collider demonstration facility at intermediate energy
C. Benedetti, S. S. Bulanov, E. Esarey +30
It is widely accepted that the next lepton collider beyond a Higgs factory would require center-of-mass energy of the order of up to 15 TeV. Since, given reasonable space and cost…

Analysis of Proton Bunch Parameters in the AWAKE Experiment
V. Hafych, A. Caldwell, R. Agnello +85
A precise characterization of the incoming proton bunch parameters is required to accurately simulate the self-modulation process in the Advanced Wakefield Experiment (AWAKE). This…
