Bubble-beam accelerators: breaking the paradigm
/ Malyzhenkov, Alexander (CERN) ; Latina, Andrea (CERN) ; Dyks, Luke (CERN) ; Corsini, Roberto (CERN) ; Farabolini, Wilfrid (CERN) ; Aksoy, Avni (CERN ; Ankara U.) ; Korysko, Pierre (JAI, UK ; CERN) ; Burrows, Philip (JAI, UK) ; Tranchedone, Lorenzo (JAI, UK ; CERN)
Most particle accelerators utilize beams with a charge density concentrated in the center of the bunch in real 3-dimensional space and the 6-dimensional phase space. In this work, by enhancing the space-charge forces in the photo-cathode injector of the Compact Linear Electron Accelerator for Research (CLEAR) at CERN, we produce electron bunches with a “bubble-like” shape, with a charge density mostly concentrated on the outside shell.

Electron beam studies on a beam position monitor based on Cherenkov diffraction radiation
/ Pakuza, Collette (JAI, UK) ; Malyzhenkov, Alexander (CERN) ; Schloegelhofer, Andreas (CERN) ; Aksoy, Avni (CERN) ; Spear, Bethany (JAI, UK) ; Senes, Eugenio (CERN) ; Lasocha, Kacper (CERN) ; Wendt, Manfred (CERN) ; Krupa, Michal (CERN) ; Chritin, Nicolas (CERN) et al.
A beam position monitor based on Cherenkov diffraction radiation (ChDR BPM) is currently under investigation to disentangle the electromagnetic field of an electron bunch from that of a proton bunch travelling together in time and space in the beam-line of the AWAKE plasma acceleration experiment at CERN. The signals from a horizontal pair of ChDR BPM radiators have been studied under a variety of beam conditions at the CLEAR electron beam test facility. [...]

The CERN Linear Electron Accelerator for Research (CLEAR) has been operating since 2017 as a user facility providing beams for various experiments. We created a start-to-end model of the CLEAR setup in RF-Track, aiming to optimise the CLEAR accelerator as a driver for an X-ray source based on inverse-Compton scattering. [...]

Updates, Status and Experiments of CLEAR, the CERN Linear Electron Accelerator for Research
/ Korysko, Pierre (Oxford U.) ; Bateman, Joseph (JAI, UK) ; Corsini, Roberto (CERN) ; Dosanjh, Manjit (CERN) ; Dyks, Luke (CERN) ; Farabolini, Wilfrid (IRFU, Saclay) ; Gilardi, Antonio (CERN) ; Rieker, Vilde (CERN) ; Robertson, Cameron (JAI, UK) ; Sjobak, Kyrre (Oslo U.)
The CERN Linear Accelerator for Research (CLEAR) at CERN is a test facility using a 200 MeV electron beam. In 2020 and 2021, a few hardware upgrades were done: comparators for position measurements were added on components, the in-air experimental area was re-arranged in order to provide more space, a robotic system was built to enable remote samples manipulations for irradiation studies, the BPM reading system was optimized and the laser double-bunch system implemented to allow for a doubling of the electron bunch frequency from 1.5 GHz to 3 GHz.

The Advanced Proton Driven Plasma Wakefield Experiment (AWAKE) at CERN uses 6 cm long proton bunches extracted from the Super Proton Synchrotron (SPS) at 400 GeV beam energy to drive high gradient plasma wakefields for the acceleration of electron bunches to 2 GeV within a 10 m length. Knowledge and control of the position of both copropagating beams is crucial for the operation of the experiment. [...]
