Searching for the best initial beam parameters for efficient muon ionization cooling
/ Stechauner, Bernd (CERN ; TU Vienna) ; Fol, Elena (CERN) ; Rogers, Chris (Rutherford) ; Schieck, Jochen (Vienna, OAW ; TU Vienna) ; Schulte, Daniel (CERN)
Ionization cooling stands as the only cooling technique capable of efficiently reducing the phase space of a muon beam within a short time frame. The optimal cooling parameters of a muon collider aim to minimize transverse emittance while simultaneously limiting longitudinal emittance growth, resulting in optimal luminosities within the collider ring.

Comparison of tracking codes for beam-matter interaction
/ Stechauner, B (CERN ; TU Vienna) ; Fol, E (CERN) ; Latina, A (CERN) ; Schulte, D (CERN) ; Rogers, C (Rutherford) ; Schieck, J (TU Vienna ; Vienna, OAW)
The interaction of particle beams with materials is important for muon colliders, as it causes particle scattering, energy loss and energy-straggling processes. Such interactions are also relevant in high-precision applications such as radiation oncology treatment planning, where the beam travels through air before reaching the patient, and are also the crucial mechanism for ionization cooling processes, such as those required for generating high-brightness beams for muon colliders.

Thermodynamic characteristics of hydrogen in an ionization cooling channel for muon colliders
/ Stechauner, B (CERN ; Vienna, Tech. U.) ; Ferreira Somoza, J A (CERN) ; Fol, E (CERN) ; Schulte, D (CERN) ; Rogers, C (Rutherford) ; Schieck, J (Vienna, OAW)
Ionization cooling is the only suitable approach to reduce the phase space volume occupied by a muon beam on a timescale compatible with the muon lifetime. Small normalized transversal emittances can be achieved by using hydrogen (H) as an absorber and high solenoid fields at low beam energy. [...]

Update of the PLACET2 code for the low-energy acceleration stages of the muon collider
/ Desire Valdor, Paula (CERN ; U. Groningen (main)) ; Latina, Andrea (CERN) ; Stechauner, Bernd (CERN ; TU Vienna) ; Costa, Raul (Uppsala U. (main))
This work describes improvements made to the tracking code PLACET2 to make it possible to simulate the acceleration from 250 MeV to 63 GeV in a future muon collider. This software was selected because of its unique ability to optimally simulate recirculating linacs, which are part of the proposed layout for this initial muon acceleration stage. [...]

HE-LHC optics design options
/ Keintzel, Jacqueline (CERN ; TU Vienna) ; Crouch, Matthew (CERN) ; Hofer, Michael (CERN ; TU Vienna) ; Risselada, Thys (CERN) ; Tomás, Rogelio (CERN) ; Zimmermann, Frank (CERN) ; van Riesen-Haupt, Léon (Oxford U. ; JAI, UK)
The High Energy Large Hadron Collider (HE-LHC), a possible successor of the High Luminosity Large Hadron Collider (HL-LHC) aims at reaching a centre-of-mass energy of about 27 TeV using basically the same 16 T dipoles as for the hadron-hadron Future Circular Collider FCC-hh. Designing the HE-LHC results in a trade off between energy reach, beam stay clear as well as geometry offset with respect to the LHC. [...]

New Longitudinal Beam Production Methods in the CERN Proton Synchrotron Booster
/ Albright, Simon (CERN) ; Antoniou, Fanouria (CERN) ; Asvesta, Foteini (CERN) ; Bartosik, Hannes (CERN) ; Bracco, Chiara (CERN) ; Renner, Elisabeth (CERN ; TU Vienna)
As part of the LHC Injectors Upgrade (LIU) project, significant improvements were made to the CERN Proton Synchrotron Booster (PSB) during the 2019/2020 long shutdown, including a new Finemet-based wideband RF system, renovated longitudinal beam control, and a new magnetic cycle. To meet the requirements of the diverse experimental program, the PSB provides beams with intensities spanning three orders of magnitude and a large range of longitudinal emittances. [...]
