Third-Generation CERN n_TOF Spallation Target: Final Design and Examinations of Irradiated Prototype
/ Esposito, Raffaele (CERN ; Ecole Polytechnique, Lausanne) ; Aberle, Oliver (CERN) ; Calviani, Marco (CERN) ; Coiffet, Thibaut (CERN) ; Crouvizier, Mickaël (CERN) ; Franqueira Ximenes, Rui (CERN) ; Maire, Vincent (CERN) ; Pérez Fontenla, Ana Teresa (CERN) ; Timmins, Marc (CERN)
The new neutron spallation target for the CERN neutron Time-Of-Flight (n_TOF) facility is based on a nitrogen-cooled Pb core impacted by short high-intensity proton beam pulses. An extensive material characterization campaign has been carried out to define the constitutive behavior of lead and assess its response under pulsed proton beam irradiation. [...]

CERN Linac4 Chopper Dump: Operational Experience and Future Upgrades
/ Sharp, Calum (CERN) ; Andreu Muñoz, Pablo (CERN) ; Calviani, Marco (CERN) ; Costa, Gabriele (CERN) ; Esposito, Luigi Salvatore (CERN) ; Franqueira Ximenes, Rui (CERN) ; Grenier, Damien (CERN) ; Grenier-Boley, Edouard (CERN) ; Hunt, James (CERN) ; Krainer, Alexander (CERN) et al.
The Chopper Dump in the Linac4 accelerator at CERN is a beam-intercepting device responsible for the absorption of the 3 MeV H⁻ ion beam produced by the Linac4 source and deflected upstream by an electromagnetic chopper. It allows a portion of the beam, which would otherwise fall into the unstable region of the radiofrequency buckets in the Proton Synchrotron Booster, to be dumped at low energy with minimal induced radiation.

Conceptual Design of a Target and Capture Channel for a Muon Collider
/ Accettura, C (CERN) ; Bottura, L (CERN) ; Calviani, M (CERN) ; Calzolari, D (CERN) ; Ximenes, R Franqueira (CERN) ; Kolehmainen, A (CERN) ; Lechner, A (CERN) ; Gomez, J Lorenzo (Fusion for Energy, Barcelona) ; Portone, A (Fusion for Energy, Barcelona) ; Esteban, F J Saura (CERN) et al.
The “target and capture channel” is one of the crucial systems in a Muon Collider, whose function is to create an intense muon beam from the decay of the pions generated by a multi-MW proton beam impinging on a particle-producing target. To guarantee the capture of the pions and resulting muons, the channel consists of a sequence of solenoids, providing a well-defined profile on axis, with 20 T peak at the target location and an adiabatic decrease along the channel length. [...]

Transverse Coherent Instability Studies for the High-Energy Part of the Muon Collider Complex

The International Muon Collider Collaboration (IMCC) is studying a 3 TeV center-of-mass muon collider ring, as well as a possible next stage at 10 TeV. Muons being 200 times heavier than electrons, limitations from synchrotron radiation are mostly suppressed, but the muon decay drives the accelerator chain design. [...]
