/ Barbera Ramos, Moises (Valencia U.) ; Bonatto, Alexandre (Rio Grande do Sul U.) ; Bontoiu, Cristian (Cockcroft Inst. Accel. Sci. Tech. ; Liverpool U.) ; Xia, Guoxing (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..

Application of Nanostructures and Metamaterials in Accelerator Physics
/ Resta-López, Javier (GACE-ICMUV) ; Apsimon, Oznur (Liverpool U.) ; Bonatto, Alexandre (Rio Grande do Sul U.) ; Bonțoiu, Cristian (Liverpool U.) ; Galante, Bruno (CERN) ; Welsch, Carsten (Liverpool U. ; Cockcroft Inst. Accel. Sci. Tech.) ; Xia, Guoxing (U. Manchester (main))
Carbon-based nanostructures and metamaterials offer extraordinary mechanical and opto-electrical properties, which make them suitable for applications in diverse fields, including, for example, bioscience, energy technology and quantum computing. In the latest years, important R&D; efforts have been made to investigate the potential use of graphene and carbon-nanotube (CNT) based structures to manipulate and accelerate particle beams. [...]

Carbon Nanotubes as Cold Electron Field Emitters for Electron Cooling in the CERN Extra Low Energy Antiproton (ELENA) Ring
/ Galante, Bruno (CERN ; Cockcroft Inst. Accel. Sci. Tech. ; Liverpool U.) ; Apsimon, Oznur (Liverpool U. ; Cockcroft Inst. Accel. Sci. Tech.) ; Resta-López, Javier (GACE-ICMUV) ; Tranquille, Gerard A (CERN) ; Welsch, Carsten P (Liverpool U. ; Cockcroft Inst. Accel. Sci. Tech.)
In ELENA electron cooling reduces the emittance of the antiproton beam allowing to deliver a high-quality beam to the experiments at the unprecedented low energy of 100 keV. To cool the antiproton beam at this low energy, the electron gun must emit electrons with as monoenergetic a distribution as possible. [...]

Design and Beam Dynamics Studies of a Novel Compact Recoil Separator Ring for Nuclear Research with Radioactive Beams
/ Resta-López, Javier (GACE-ICMUV) ; Foussat, Arnaud (CERN) ; Kirby, Glyn (CERN) ; Martel, Ismael (Huelva U.) ; Rodin, Volodymyr (Liverpool U. ; Cockcroft Inst. Accel. Sci. Tech.)
The recent development of radioactive beam facilities has significantly expanded the capabilities for investigating the structure of the atomic nucleus and the nuclear interaction. For instance, the HIE-ISOLDE facility at CERN delivers presently the largest range of low-energy radioactive beam available worldwide. [...]

Nanoplasmonic Accelerators Towards Tens of TeraVolts per Meter Gradients Using Nanomaterials
/ Sahai, Aakash A (Colorado U., Denver) ; Golkowski, Mark (Colorado U., Denver) ; Harid, Vijay (Colorado U., Denver) ; Joshi, Chan (UCLA) ; Katsouleas, Tom (Connecticut U.) ; Latina, Andrea (CERN) ; Resta-López, Javier (Valencia U.) ; Taborek, Peter (UC, Irvine) ; Thomas, Alexander (Michigan U.) ; Zimmermann, Frank (CERN)
Ultra-high gradients which are critical for future advances in high-energy physics, have so far relied on plasma and dielectric accelerating structures. While bulk crystals were predicted to offer unparalleled TV/m gradients that are at least two orders of magnitude higher than gaseous plasmas, crystal-based acceleration has not been realized in practice.
