Measurement of the emittance of accelerated electron bunches at the AWAKE experiment / AWAKE Collaboration
The vertical plane transverse emittance of accelerated electron bunches at the AWAKE experiment at CERN has been determined, using three different methods of data analysis. [...]

Experimental Observation of Motion of Ions in a Resonantly Driven Plasma Wakefield Accelerator / AWAKE Collaboration
We show experimentally that an effect of motion of ions, observed in a plasma-based accelerator, depends inversely on the plasma ion mass. [...]

A Generic Real-Time Software in C++ for Digital Camera-Based Acquisition Systems at CERN / Topaloudis, Athanasios (CERN) ; Bravin, Enrico (CERN) ; Burger, Stephane (CERN) ; Jackson, Stephen (CERN) ; Mazzoni, Stefano (CERN) ; Poimenidou, Eirini (CERN) ; Senes, Eugenio (CERN)
Until recently, most of CERN’s beam visualisation systems have been based on increasingly obsolescent analogue cameras. Hence, there is an on-going campaign to replace old or install new digital equivalents. [...]

Review of CERN beam instrumentation for fixed target experiments / Roncarolo, Federico (CERN) ; Burger, Stephane (CERN) ; Guerrero, Ana (CERN) ; Lefevre, Thibaut (CERN) ; Levens, Thomas (CERN) ; Topaloudis, Athanasios (CERN) ; Trad, Georges (CERN) ; Velotti, Francesco (CERN)
Measuring beam parameters in the vicinity of fixed target experiments or interceptive devices like beam dumps is essential to ensure efficient fixed target physics and safe beam operation. At the same time the beam diagnostic reach is very often challenging in terms of robustness and performance. [...]

Hosing of a long relativistic particle bunch in plasma / AWAKE Collaboration
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 misalignment, self-modulation in the perpendicular plane, at frequencies close to the plasma electron frequency, and are reproducible. [...]

Filamentation of a Relativistic Proton Bunch in Plasma / AWAKE Collaboration
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 threshold value for the ratio between the bunch transverse size and plasma skin depth for the instability to occur. [...]

Development of the Self-Modulation Instability of a Relativistic Proton Bunch in Plasma / AWAKE Collaboration
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 showing that, when increasing the ratio between the initial transverse size of the bunch and the plasma skin depth, the instability occurs later along the bunch, or not at all, over a fixed plasma length, because the amplitude of the initial wakefields decreases. [...]

The Advanced Wakefield Experiment (AWAKE) at CERN investigates the Plasma-Wakefield acceleration of electrons driven by a relativistic proton bunch. After successfully demonstrating the acceleration process in the AWAKE Run 1, the experiment has now started the Run 2. [...]

New CERN SPS Beam Dump Imaging System / Burger, Stephane (CERN) ; Bravin, Enrico (CERN) ; Roncarolo, Federico (CERN) ; Topaloudis, Athanasios (CERN) ; Velotti, Francesco (CERN) ; Veyrunes, Eric (CERN)
As part of the LHC injector Upgrade (LIU), the CERN SPS is now equipped with a new Beam Dumping System (SBDS) designed to cope with the high power beams foreseen for the High Luminosity LHC (HL-LHC) era. Before reaching the dump, the proton beam (from 26 to 450 GeV) is vertically kicked and then diluted passing through a series of horizontal and vertical bumps. [...]

Commissioning of ALPS, the New Beam Position Monitor System of CERN’s Super Proton Synchrotron / Boccardi, Andrea (CERN) ; Albertone, Joel (CERN) ; Barros Marin, Manoel (CERN) ; Bogey, Thierry (CERN) ; Kain, Verena (CERN) ; Li, Kevin S B (CERN) ; Malinowska, Patrycja A (CERN ; AGH-UST, Cracow) ; Topaloudis, Athanasios (CERN) ; Wendt, Manfred (CERN)
The Super Proton Synchrotron (SPS) is both, the final machine in the pre-accelerator chain of the Large Hadron Collider (LHC) at CERN, and a machine providing several experiments with proton and ion beams. In the framework of CERN’s LHC Injectors Upgrade (LIU) project, aimed at improving the performances of the pre-accelerators in view of the high-luminosity upgrade of the LHC, the Beam Position Monitor (BPM) system of the SPS was redesigned during Run 2 of the LHC and deployed during the subsequent Long Shutdown 2 (LS2).
