Quantifying the Heat Load to Conductors Due to Strain Energy Release in CTD-101 K Magnet Impregnant / van Steenlandt, Jan (Twente U., Enschede) ; Kario, Anna (Twente U., Enschede) ; Otten, Simon (Twente U., Enschede) ; Warnet, Laurent (Twente U., Enschede) ; Wessel, Sander (Twente U., Enschede) ; ten Kate, Herman (Twente U., Enschede) ; van Oort, Hans (Twente U., Enschede)
State-of-the-art Nb3Sn superconducting accelerator magnets are still prone to lengthy training. This study investigates whether direct heat from fractures in commonly used magnet impregnant is sufficient to cause the instabilities during training. [...]

Design of a multipurpose test facility (MTF) for HTS cables / Ballarino, Amalia (CERN) ; Barth, Christian (CERN) ; Masci, Marco (CERN) ; Perini, Diego (CERN)
The High Field Magnet (HFM) program foresees, among others, the systematic measurement and assessment of mechanical, thermal, and electrical properties of high temperature superconductors (HTS) cables. These measurements are a key factor to characterize the conductor, verify its performance and control the production quality. [...]

Experimental validation of a versatile test bench for thermal contraction measurements down to 1.8 K / Höll, Stefan (CERN) ; Guinchard, Michael (CERN) ; De Frutos, Óscar Sacristán (CERN)
The use of cryogenics plays a major role in the operation of modern high-energy accelerators and ensures, for instance, the superconducting state of beam-guiding and focusing magnets. A profound understanding of the thermo-mechanical behavior of the structures and components is therefore crucial, particularly for the strain-sensitive Nb$_{3}$Sn-based superconducting coils. [...]

High Luminosity LHC Optics Feasibility Studies for: ATLAS, ALICE, and LHCb / Patel, Pragati (Cracow, INP) ; Trzebiński, Maciej (Cracow, INP)
Properties of proton trajectories along the High Luminosity LHC beam-line in the vicinity of ATLAS, ALICE, and LHCb interaction points are discussed. Based on this, possible locations of forward proton detectors in the vicinity of these experiments were identified. [...]

Space Charge in Circular Machines / Ferrario, Massimo (U. Rome La Sapienza (main) ; Frascati) ; Migliorati, Mauro (Frascati ; U. Rome La Sapienza (main)) ; Palumbo, Luigi (U. Rome La Sapienza (main) ; Frascati)
Space charge forces, which arise directly from the beam's charge distribution and include the influence of image charges and currents induced by interactions with a perfectly conducting, smooth pipe, are very important in high-intensity, low-energy accelerators. [...]

Numerical application of the mode matching technique to the longitudinal impedance computation in particle accelerators / Biancacci, N (CERN) ; Passarelli, A (INFN, Naples)
The accurate knowledge of the beam coupling impedance in particle accelerators is important in order to address potential impedance-driven instabilities and for planning machine upgrades. While simple models exist for various components (e.g., beam pipes, step transitions, and collimators), they are often insufficient to correctly describe the overall machine impedance with the necessary precision.
