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. [...]

Beam lifetime monitoring using beam loss monitors during LHC Run 3 / Morales Vigo, S (CERN ; Cockcroft Inst. Accel. Sci. Tech.) ; Salvachua, B (CERN) ; Welsch, C P (Cockcroft Inst. Accel. Sci. Tech.) ; Zamantzas, C (CERN) ; Wolfenden, J (Cockcroft Inst. Accel. Sci. Tech.) ; Hermes, P (CERN) ; Redaelli, S (CERN)
The Beam Loss Monitoring (BLM) system of the Large Hadron Collider (LHC) at CERN is essential for the protection of machine elements against energy deposition from beam losses. Employing around 4000 detectors placed around the 27-km LHC ring, the BLM system measures secondary particles continuously and can trigger beam extraction in less than 3 turns, in case the signals exceed certain predetermined thresholds. [...]

Calibration of the LHC Diamond beam loss monitors for LHC Run 3 / Morales Vigo, Sara (CERN ; Cockcroft Inst. Accel. Sci. Tech.) ; Salvachua, Belen (CERN) ; Welsch, Carsten (Cockcroft Inst. Accel. Sci. Tech.) ; Zamantzas, Christos (CERN) ; Calvo Giraldo, Eva (CERN) ; Martinez Samblas, Javier (CERN) ; Wolfenden, Joseph (Cockcroft Inst. Accel. Sci. Tech.) ; Gonzalez-Berges, Manuel (CERN)
A set of twelve Polycrystalline Chemical Vapour Deposition (pCVD) diamond detectors are installed in the beam injection, extraction and betatron collimation areas of the Large Hadron Collider (LHC) as fast beam loss monitoring detectors. Their high-radiation tolerance and time resolution in the order of a few ns makes them an ideal candidate to monitor bunch-by-bunch losses in the LHC beams, which have a nominal bunch separation of 25 ns. [...]

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. [...]

Linearity and Response Time of the LHC Diamond Beam Loss Monitors in the CLEAR Beam Test Facility at CERN / Morales Vigo, Sara (CERN ; Cockcroft Inst. Accel. Sci. Tech.) ; Calvo Giraldo, Eva (CERN) ; Dyks, Luke (CERN) ; Effinger, Ewald (CERN) ; Farabolini, Wilfrid (CERN) ; Korysko, Pierre (CERN) ; Lernevall, Anders (CERN) ; Salvachúa, Belen (CERN) ; Welsch, Carsten (Cockcroft Inst. Accel. Sci. Tech.) ; Wolfenden, Joseph (Cockcroft Inst. Accel. Sci. Tech.) et al.
Chemical Vapour Deposition (CVD) diamond detectors have been tested during the Run 2 operation period (2015-2018) as fast beam loss monitors for the Beam Loss Monitoring (BLM) system of the Large Hadron Collider (LHC) at CERN. However, the lack of raw data recorded during this operation period restrains our ability to perform a deep analysis of their signals. [...]

EuPRAXIA – a compact, cost-efficient particle and radiation source / Weikum, M K (DESY) ; Akhter, T (INFN, Naples) ; Alesini, P D (LNF, Dafne Light) ; Alexandrova, A S (Cockcroft Inst. Accel. Sci.

Plasma accelerators present one of the most suitable candidates for the development of more compact particle acceleration technologies, yet they still lag behind radiofrequency (RF)-based devices when it comes to beam quality, control, stability and power efficiency. The Horizon 2020-funded project EuPRAXIA (“European Plasma Research Accelerator with eXcellence In Applications”) aims to overcome the first three of these hurdles by developing a conceptual design for a first international user facility based on plasma acceleration.
