Tech. ; Manchester U.) ; Xia, G (Cockcroft Inst. Accel. Sci. Tech. ; Manchester U.) ; Apsimon, O (Cockcroft Inst. Accel. Sci. Tech. ; Manchester U.) ; McGunigal, J (Cockcroft Inst. Accel. Sci.

This paper presents the design and experimental commissioning of a noninvasive electron bunch length monitor based on the detection of coherent Cherenkov diffraction radiation (ChDR). The measurement technique effectively eliminates the influence of bunch-by-bunch charge fluctuations, as each detector measures the signal from the same bunch while mitigating the impact of bunch position jitter on the measurements, providing a potential real-time diagnostic tool with significant operational advantages.

Experimental observation of the 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. The effect appears within a single wakefield event and manifests itself as a bunch tail, occurring only when sufficient motion of ions suppresses wakefields. [...]

Elevating electron energy gain and betatron X-ray emission in proton-driven wakefield acceleration / Saberi, Hossein (Manchester U. ; Daresbury) ; Xia, Guoxing (Manchester U. ; Daresbury) ; Liang, Linbo (Manchester U. ; Daresbury) ; Farmer, John Patrick (CERN ; Munich, Max Planck Inst.) ; Pukhov, Alexander (Heinrich Heine U., Dusseldorf)
The long proton beams present at CERN have the potential to evolve into a train of microbunches through the self-modulation instability process. The resonant wakefield generated by a periodic train of proton microbunches can establish a high acceleration field within the plasma, facilitating electron acceleration. [...]

Driver-witness configuration in CNT array-based acceleration / Barbera Ramos, Moises (Valencia U.) ; Bonatto, Alexandre (Rio Grande do Sul U.) ; Bontoiu, Cristian (Cockcroft Inst. Accel. Sci.

Solid-state plasma wakefield acceleration might be an alternative to accelerate particles with ultra-high accelerating gradients, in the order of TV/m.In addition, due to their thermodynamic properties, 2D carbon-based materials, such as graphene layers and/or carbon nanotubes (CNT) are good candidates to be used as the media to sustain such ultra-high gradients. In particular, due to their cylindrical symmetry, multi-nm-aperture targets, made of CNT bundles or arrays may facilitate particle channelling through the crystalline structure.In this work, a two-bunch, driver-and-witness configuration is proposed to demonstrate the potential to achieve particle acceleration as the bunches propagate along a CNT-array structure.Particle-in-cell simulations have been performed using the VSIM code in a 2D Cartesian geometry to study the acceleration of the second (witness) bunch caused by the wakefield driven by the first (driver) bunch.The effective plasma-density approach was adopted to estimate the wakefield wavelength, which was used to identify the ideal separation between the two bunches, aiming to optimize the witness-bunch acceleration and focusing.Simulation results show the high acceleration gradient obtained, and the energy transfer from the driver to the witness bunch..

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. [...]

Characteristics of betatron radiation in AWAKE Run 2 experiment / Liang, Linbo (Manchester U. ; SLAC, SSRL) ; Saberi, Hossein (Manchester U. ; SLAC, SSRL) ; Xia, Guoxing (Manchester U. ; SLAC, SSRL) ; Farmer, John Patrick (CERN ; Munich, Max Planck Inst.) ; Pukhov, Alexander (Heinrich Heine U., Dusseldorf)
The oscillating relativistic electrons in the accelerating/focusing wakefields of plasma accelerators emit electromagnetic radiation known as betatron radiation (BR). The proton-driven plasma wakefield acceleration has been demonstrated in the Advanced Wakefield Experiment (AWAKE) at CERN; however, its accompanying radiation emission is less explored compared with those in the laser- and electron beam-driven plasma accelerators.

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. [...]
