Mariya Arsentyeva (Synchrotron Radiation Facility — Siberian Circular Photon Source «SKIF» Boreskov Institute of Catalysis)18/08/2026, 15:00MC1.A01: Beam Dynamics, beam simulations, beam transportPoster Presentation
Linear accelerator of the SKIF Synchrotron Radation Facility (SRF SKIF) was sucessfully commissioned in 2025. It provides the electron beams with the energy of 200 MeV for the subsequent injection to the booster synchrotron. Being an initial part of the SRF SKIF, the linear accelerator includes not only the key components, such as the electron gun, accelerating structures and magnet elements,...

Mr Yutaro Kubo (Kyoto University)18/08/2026, 15:05MC1.A02 Electron and ion sources, guns, photo injectors, charge breedersPoster Presentation
Cs-Te photocathodes are widely used in photoinjectors for free electron lasers owing to their high quantum efficiency (QE). At KU-FEL, an infrared oscillator-type FEL in Kyoto University, a 1.6-cell RF gun with CsBr-coated Cs-Te photocathode* has been developed for high-bunch-charge (~1 nC) multi-bunch operation. However, the QE and lifetime of the cathode in our RF gun are insufficient for...

455. Bayesian Optimization for Constrained Beam Transport Line Design in the RAON Injector (TUOP003)Chanmi Kim (Institute for Basic Science)18/08/2026, 15:10MC1.A01: Beam Dynamics, beam simulations, beam transportPoster Presentation
The design of low-energy beam transport (LEBT) lines involves high-dimensional optimization under multiple physical constraints, including beam size, transmission efficiency, and limited beamline geometry. In the RAON injector system, the integration of a new 14.5 GHz ECR ion source requires re-optimization of the beam transport line while maintaining compatibility with the existing injector...

Last preparations for operation for users are ongoing at the new basic facility of the Laboratory of Nuclear Problems of the Joint Institute for Nuclear Research — the LINAC (formerly LINAC-200) accelerator. The facility can provide electron beam with a wide range of energies (5 to 200 MeV), pulse durations (0.25 to 3 us) and charges (240 nC to single electrons per pulse). The maximum pulse...

Paula Desire Valdor (European Organization for Nuclear Research)18/08/2026, 15:20MC2.A04: FELsPoster Presentation
Intrabeam Scattering (IBS) has recently been recognized as a limiting factor for free electron laser (FEL) performance, making it a critical concern for the linear accelerator community. There is a growing need for accurate numerical tools to compute IBS and integrate it with other collective effects, as most previous studies assumed Gaussian beams, which are not representative of FEL...

The ongoing multi-user upgrade of the superconducting ion linac, ATLAS at Argonne, will enable simultaneous acceleration and delivery of two different ion beams to different experimental areas. One nearly continuous stable beam from the ECR ion source and one pulsed radioactive beam from the EBIS charge breeder of nuCARIBU will be interleaved in time via an electrostatic deflector at injection...

Prof. Holger Podlech (Goethe University Frankfurt, HFHF - Helmholtz Research Academy Hesse for FAIR, Campus Frankfurt)18/08/2026, 15:30MC3.A04: Proton linac projectsPoster Presentation
Neutrons are an essential tool for studying the structure and dynamics of matter. The High Brilliance Neutron Source (HBS) project aims to develop a scalable Compact Accelerator-driven Neutron Source that will enable neutron fluxes at the corresponding instruments comparable to existing fission-based or spallation neutron sources. After positive project evaluation in 2025, the German Science...

Zhiping Li (Institute of High Energy Physics)18/08/2026, 15:35MC3.A04: Proton linac projectsPoster Presentation
The CSNS linac delivers a primary H⁻ beam to the RCS while also providing stripped proton beams generated through two mechanisms: foil stripping and intra-beam stripping. Carbon foil collimators selectively strip halo particles from the beam periphery, reducing the transverse emittance of the H⁻ beam, which allows a larger painting range during RCS injection and reduces beam loss. Intra-beam...

Compared with subtractive manufacturing methods such as CNC machining, additive manufacturing (AM) enables the fabrication of highly complex monolithic geometries. As a result, AM can improve functionality and reduce manufacturing costs. For linear accelerator (linac) components, this potential has been demonstrated in a growing number of studies and prototype developments. At the same time,...

The development of a muon-dedicated traveling-wave disk-loaded structure (DLS) is in progress at the Japan Proton Accelerator Research Complex (J-PARC). Accelerating ultraslow muons to relativistic energies preserves low beam emittance and improves penetration capability, enabling new opportunities in precision particle physics experiments and muon imaging. However, unlike electrons, muons...

Jiyoung Choi (Pohang University of Science and Technology)18/08/2026, 15:50MC4.A01: Beam diagnosticsPoster Presentation
Precise 4-dimensional (4D) transverse phase space characterization is essential for fully understanding and controlling coupled beam dynamics and beam quality. The Virtual Pepper-Pot (VPP) method has been proposed to reconstruct the 4D transverse phase space, including transverse coupling information, from slit-based measurements. However, the finite slit width imposes intrinsic limitations on...
