Filled Thermoplastic Based Coating for Tailored Contact Resistance in HTS Coils / Crescenti, Matteo (PSI, Villigen ; U. Geneva (main)) ; Auchmann, Bernhard (CERN ; PSI, Villigen) ; Brem, André (PSI, Villigen) ; Duda, Michał (PSI, Villigen) ; Kosse, Jaap (PSI, Villigen) ; Müller, Colin (PSI, Villigen) ; Puthran, Kirtana (PSI, Villigen) ; Rodrigues, Henrique (PSI, Villigen) ; Schmidt, Jürgen (PSI, Villigen) ; Senatore, Carmine (U. Geneva (main))
We present a systematic method to tune the turn-to- turn contact resistance Rct in high-temperature superconducting (HTS) solenoids by applying a polyvinyl butyral (PVB) thermoplas- tic coating filled with silver-coated copper flakes (SCCF). The filler type and its volume fraction determines the accessible resistance range in the final coil. [...]

Particle accelerators, such as the Large Hadron Collider (LHC) at CERN, are planning to increase the intensity of circulating particle beams. However, this upgrade faces challenges due to beam-induced heating that can lead to operational issues and component damage. [...]

Post long shutdown 2 CERN proton synchrotron transverse impedance model: Description and beam-based validation / Joly, Sébastien (U. Rome La Sapienza (main)) ; Migliorati, Mauro (INFN, Rome) ; Mounet, Nicolas (CERN) ; Salvant, Benoît (CERN)
In the framework of the LHC Injectors Upgrade project, the CERN Proton Synchrotron underwent hardware changes during the Long Shutdown 2. These changes required an update of the CERN Proton Synchrotron impedance model and an assessment of their impact on beam quality. [...]

Environmental Measurements in the Sedrun Access Shaft to the Gotthard Base Tunnel - a Promising Site for a Long-Baseline Atom Interferometer / Guinchard, M. ; Buchmüller, O. ; Calatroni, S. ; Ellis, J. ; Hoell, S. ; Jaussi, M. ; Lombriser, L. ; Pentella, M. ; Thuliez, D. ; Valuch, D.
Atom interferometer (AI) experiments offer interesting prospects for searches for the interactions of ultralight bosonic dark matter with Standard Model particles as well as detection of gravitational waves in a frequency band inaccessible to experiments that are operating or under construction. Ideal locations for the next generation of such experiments are provided by long vertical shafts, such as that providing access to the Gotthard base railway tunnel from the Sedrun locality in the Canton Grisons of Switzerland.
