A decomposition algorithm for streak camera data / Oguzhan, Kaan (Munich, Max Planck Inst.) ; Ranc, Lucas (Munich, Max Planck Inst.) ; Verra, Livio (CERN) ; Caldwell, Allen (Munich, Max Planck Inst.)
We describe a novel reconstruction algorithm for time-resolved images obtained using a streak camera. This algorithm operates by decomposing a recorded image into a set of individual photoelectron-induced signals, thereby providing a powerful method for streak camera image reconstruction. [...]

Techniques to seed the self-modulation instability of a long proton bunch in plasma / Verra, Livio (CERN) ; Bergamaschi, Michele (Munich, Max Planck Inst.) ; Zevi Della Porta, Giovanni (CERN ; Munich, Max Planck Inst.) ; Gschwendtner, Edda (CERN) ; Muggli, Patric (Munich, Max Planck Inst.)
The Advanced Wakefield Experiment (AWAKE) at CERN relies on the seeded Self-Modulation (SM) of a long relativistic proton bunch in plasma to accelerate an externally injected MeV witness electron bunch to GeV energies. During AWAKE Run 1 (2016-2018) and Run 2a (2021-2022), two seeding methods were investigated experimentally: relativistic ionization front seeding and electron bunch seeding. [...]

Focusing of a Long Relativistic Proton Bunch in Underdense Plasma / Verra, Livio (CERN) ; Gschwendtner, Edda (CERN) ; Muggli, Patric (Munich, Max Planck Inst.)
We discuss the focusing effect experienced by a long relativistic proton bunch, when propagating in underdense plasma. [...]

A Method for Obtaining 3D Charge Density Distribution of a Self-Modulated Proton Bunch / Nechaeva, Tatiana (Munich, Max Planck Inst. HLL) ; Muggli, Patric (Munich, Max Planck Inst. HLL) ; Verra, Livio (CERN ; Munich, Tech. U. ; Munich, Max Planck Inst. HLL) ; Zevi Della Porta, Giovanni (CERN) /AWAKE Collaboration
The Advanced Wakefield Experiment (AWAKE) at CERN is the first plasma wakefield accelerator experiment to use a proton bunch as driver. The long bunch undergoes seeded self-modulation (SSM) in a 10 m-long plasma. [...]

The AWAKE Experiment in 2021: Performance and Preliminary Results on Electron-Seeding of Self-Modulation / Gschwendtner, Edda (CERN) ; Muggli, Patric (Munich, Max Planck Inst.) ; Verra, Livio (CERN) ; Zevi Della Porta, Giovanni (CERN) /AWAKE Collaboration
The future programme of the Advanced Wakefield (AWAKE) experiment at CERN relies on the seeded self-modulation of an entire proton bunch, resulting in phase-reproducible micro-bunches. This important milestone was achieved during the 2021 proton run by injecting a short electron bunch ahead of the proton bunch, demonstrating for the first time the electron-seeding of proton bunch self-modulation [...]

Mapping charge capture and acceleration in a plasma wakefield of a proton bunch using variable emittance electron beam injection / AWAKE Collaboration
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 plasma column. In this work, we analyze the overall charge capture and shot-to-shot reproducibility of the proton-driven plasma wakefield accelerator with various electron bunch injection parameters. [...]

The AWAKE Run 2 programme and beyond / AWAKE Collaboration
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 during Run 1 of the AWAKE programme at CERN. [...]

Preparation for Electron-Seeding of Proton Bunch Self-Modulation in AWAKE / Zevi Della Porta, Giovanni (CERN) ; Gschwendtner, Edda (CERN) ; Moon, Kookjin (UNIST, Ulsan) ; Muggli, Patric (Munich, Max Planck Inst.) ; Verra, Livio (CERN ; Munich, Max Planck Inst.)
The next milestone of the Advanced Wakefield Experiment (AWAKE) at CERN will be to demonstrate that the self-modulation of a long proton bunch can be seeded by a short electron bunch preceding it. This seeding method will lead to phase-reproducible self-modulation of the entire proton bunch, as required for the future AWAKE program. [...]

Design of the Proton and Electron Transfer Lines for AWAKE Run 2c / Ramjiawan, Rebecca (JAI, UK ; CERN) ; Döbert, Steffen (CERN) ; Farmer, John (Munich, Max Planck Inst. ; CERN) ; Gschwendtner, Edda (CERN) ; Muggli, Patric (Munich, Max Planck Inst. ; CERN) ; Velotti, Francesco (CERN) ; Verra, Livio (CERN)
The AWAKE Run 1 experiment achieved electron acceleration to 2 GeV using plasma wakefield acceleration driven by 400 GeV, self-modulated proton bunches from the CERN SPS. The Run 2c phase of the experiment aims to build on these results by demonstrating acceleration to ~10 GeV while preserving the quality of the accelerated electron beam. [...]
