Cryogenic options for future accelerators: case study for the Muon Collider ring
/ Borges De Sousa, P (CERN) ; Naydenov, B (CERN) ; Delprat, L (CERN) ; Koettig, T (CERN) ; Van Weelderen, R (CERN)
Future, multi-km particle accelerator projects will be under heavy scrutiny to be energetically sustainable. Compared to previous accelerators, these machines must sustain increasingly high beam-induced, static, and dynamic heat loads per meter length. [...]

Design Margin Comparison of a Sextupole-in-Solenoid and a Closed-Loop-Coil Type Nb-Ti Superconducting ECR Magnets
/ Yang, Ye (LBNL, Berkeley) ; Ferracin, Paolo (LBNL, Berkeley) ; Troitiño, Jose Ferradás (CERN) ; Juchno, Mariusz (LBNL, Berkeley) ; Benitez, Janilee (LBNL, Berkeley) ; Todd, Damon (LBNL, Berkeley) ; Xu, Lianrong (LBNL, Berkeley) ; Duran, Jaime Cruz (LBNL, Berkeley) ; Arbelaez, Diego (LBNL, Berkeley) ; Shen, Tengming (LBNL, Berkeley) et al.
Third-generation electron cyclotron resonance ion sources (ECRISs) have relied on a combination of sextupole and solenoid fields from Nb-Ti superconductors to produce the magnetic fields required for 28 GHz operation. The VENUS ion source at Lawrence Berkeley National Laboratory (LBNL) was the first third-generation ion source optimized for 28 GHz operation, and since that time a similar design has been adopted at other heavy-ion facilities such as RIKEN, GANIL and FRIB. [...]

Assessing the origin of the LHC beam halo
/ Rakic, Milica (CERN ; Ecole Polytechnique, Lausanne) ; Hermes, Pascal (CERN) ; Redaelli, Stefano (CERN) ; Butti, Daniele (CERN) ; Mirarchi, Daniele (CERN) ; Roncarolo, Federico (CERN) ; Bartosik, Hannes (CERN) ; Hostettler, Michi (CERN) ; Kostoglou, Sofia (CERN) ; Seidel, Mike (PSI, Villigen)
Measurements of the transverse beam-halo population at large amplitudes in the Large Hadron Collider (LHC) provide crucial insights into the stored beam energy near the LHC collimators. These particles do not contribute significantly to the luminosity but their loss could impose limitations on accelerator performance through sudden loss spikes or even collimator damage in case of fast beam failures. [...]
