Damping ring and transfer lines of FCC-𝑒+𝑒− injector complex / Spampinati, Simone (Frascati) ; De Santis, Antonio (Frascati) ; Dutheil, Yann (CERN) ; Etisken, Ozgur (Kirikkale U. ; Frascati) ; Ramjiawan, Rebecca (CERN) ; Milardi, Catia (Frascati)
The Future Circular Collider project is built around two main pillars: the construction of 100 km lepton collider running at increasing energies from the Z-pole to the t-tbar threshold (FCC-ee) followed by a hadron collider in the same tunnel (FCC-hh) to explore unprecedented energy frontier.The realization of FCC-ee relies on a very challenging injector complex that should provide the highest ever realized source of positrons, which will serve the first phase of the collider operations (Z-pole). In this contribution the relevant aspects related to the damping of the high-emittance beam coming from the positron source and the transport of the damped beam within the different LINAC of the injector complex are presented and discussed..

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. [...]

FCC-ee $e^+e^-$ Injection and Booster rRng / Ramjiawan, Rebecca (CERN) ; Barnes, Michael (CERN) ; Bartmann, Wolfgang (CERN) ; Borburgh, Jan (CERN) ; Chancé, Antoine (Saclay) ; Dalena, Barbara (IRFU, Saclay) ; Dutheil, Yann (CERN) ; Hofer, Michael (CERN) ; Howling, Emily (Royal Holloway, U. of London) ; Hunchak, Patrick (Saskatchewan U.)
The Future Circular electron-positron Collider (FCC-ee) is a proposal for a 91.17 km collider, which would operate in four modes with energies ranging from 45.6 GeV (Z-pole) to 182.5 GeV (ttbar-production). At high energies the beam lifetime could be as low as 6 minutes, requiring the beam to be continuously topped up to reach a high integrated luminosity. [...]

Investigating the feasibility of delivering higher intensity proton beams to ECN3 at the CERN SPS North Area / Fraser, M A (CERN) ; Brugger, M (CERN) ; Ahdida, C (CERN) ; Arduini, G (CERN) ; Arrutia Sota, P A (CERN) ; Bartosik, H (CERN) ; Bernhard, J (CERN) ; Calviani, M (CERN) ; Colinet, A (CERN) ; Esposito, L S (CERN) et al.
Initiated through the Physics Beyond Colliders (PBC) Study Group there is a strong interest from the scientific community to exploit the full intensity potential of the Super Proton Synchrotron (SPS) at CERN for Fixed Target physics experiments before the end of this decade. With the ECN3 cavern in the North Area (NA) identified as a suitable candidate location for a future high-intensity experimental facility compatible with a large variety of experiments, the new PBC ECN3 Beam Delivery Task Force was mandated to assess the feasibility of delivering a slow extracted beam of up to 4x10^19 protons per year at 400 GeV.

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. [...]

Target systems design for a high intensity facility in the CERN's ECN3 area / Ximenes, R F (CERN) ; Grenard, J-L (CERN) ; Ruiz, J M Martin (CERN) ; Ahdida, C (CERN) ; Bernhard, J (CERN) ; Brugger, M (CERN) ; Calviani, M (CERN) ; Esposito, L (CERN) ; Fraser, M (CERN) ; Jacobsson, R (CERN) et al.
A new high intensity fixed target facility could be accommodated at CERN by fully exploiting the Super Proton Synchrotron. Multiple physics experiment proposals such as BDF/SHiP, NA62-BD, HIKE and SHADOWS are being considered. [...]

Assessment of beam-intercepting device robustness for intensity increase in CERN’s North Area / Sharp, C J (CERN) ; Francia, A Romero (CERN) ; Ximenes, R Franqueira (CERN) ; Calviani, M (CERN) ; Grenard, J -L (CERN) ; Mazzola, G (CERN) ; Esposito, L S (CERN) ; Bernhard, J (CERN) ; Mazuecos, A Lafuente (CERN) ; Galan, F Sanchez (CERN) et al.
CERN's North Area comprises several target and experimental systems and is a zone of interest for future development. Provision of beam to this area relies upon several beam-intercepting devices located in various branched transfer lines from the Super Proton Synchrotron. [...]

TT20 unsplit beam optics for dedicated ECN3 operation / Ramjiawan, Rebecca Louise (CERN) ; Velotti, Francesco Maria (CERN) ; Fraser, Matthew Alexander (CERN)
The Transfer Tunnel 20 (TT20) in the CERN North Area (NA) contains transfer lines TT21-25 to transport beam extracted from the Super Proton Synchrotron (SPS). The beam is shared between three primary production targets simultaneously using two sets of Lamberston septa magnets [...]

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. [...]
