F-divergence can be used to precisely quantify the differences between beam distributions in high-dimensional phase space, as it comprehensively captures the total contribution of discrepancies from all points in phase space. Current applications of f-divergence are primarily confined to the static comparison of distributions. This paper aims to investigate its evolution during beam transport....

Second beam line has recently been installed and commissioned at CLEAR (CERN Linear Accelerator for Research). The line begins with a switchyard consisting of two dipole bending magnets that offset the beam from its original path, along with quadrupoles and sextupoles placed between the bends to close the first- and second-order dispersion, respectively. In this work, based on analytical...

The KEK-ATF is an R&D facility for the final focus system to develop nanometer beam technology for the International Linear Collider. The vertical beam size growth as a function of bunch intensity has been observed at the focal point (IP), mainly caused by wakefield effects. ATF provides an excellent environment for studying wakefield impacts on nanometer-scale beams. Mitigation and...

The dielectric assist accelerating (DAA) structure is a power-efficient RF accelerating cavity. A room-temperature C-band DAA structure has demonstrated a high shunt impedance of approximately 600 MΩ/m. Nevertheless, the attainable accelerating field in DAA structures has so far been limited to approximately 10–12 MV/m, mainly because of RF breakdown-related phenomena, including...

The Soreq Applied Research Accelerator Facility (SARAF) is advancing to Phase II to deliver continuous wave proton and deuteron beams (5-40 MeV, ~5 mA). Handling the resulting ~200 kW beam power requires a robust dump capable of dissipating high power densities. To meet this challenge, a windowless liquid Gallium-Indium (Ga-In) jet target, GaLiT,* was designed. It generates a stable ~5 m/s...

CERN's Linear Accelerator 4 (Linac4) is an H⁻ accelerator that has been in operation since 2020. After acceleration, the ions are converted to protons via electron stripping and sent downstream to various experiments on the CERN site. Its first accelerating structure is a 3 m long Radio-Frequency Quadrupole (RFQ), operating at 78 kV inter-vane voltage and a peak surface field of 34 MV/m. In...

The CAFE2 accelerator, upgraded from CAFe at IMP, supports superheavy element research. Based on the RAMI framework, this paper decomposes CAFE2 using PBS and applies fault tree analysis at system, subsystem, and equipment levels to identify beam trip events. Historical data show that the superconducting section and control system are the main causes of beam losses. Although CAFE2 has high...

The proposed energy upgrade of the Continuous Electron Beam Accelerator Facility (CEBAF) incorporates Fixed-Field Alternating-gradient (FFA) arcs utilizing permanent magnet technology. Given the radiation environment within the CEBAF tunnel enclosure, validating the long-term magnetic stability of these materials is a critical step for the project's technical feasibility. This contribution...

Machine learning (ML) is increasingly recognized as a fundamental tool in modern accelerator physics, offering new capabilities to complement and extend traditional analytical approaches. A structured programme of ML studies has been initiated at CLEAR (CERN Linear Electron Accelerator for Research), covering three principal directions: beam diagnostics, charge forecasting, and automated...

The J-PARC Muon Linac is being developed for precision measurements of the muon anomalous magnetic moment and the search for the muon electric dipole moment using a reaccelerated thermal muon beam. The Medium Energy Beam Transport (MEBT) line, planned for commissioning in 2027, will transport and match the muon beam to the Inter-digital H-mode drift tube linac (IH-DTL). Because the expected...
