    The Korean 4GSR project is currently under construction in Ochang, South Korea, with the aim of achieving first beam commissioning in 2027.
    Designed to achieve an emittance approximately 100 times smaller than that of third-generation synchrotron radiation storage rings, the project requires the development of several high-precision beam diagnostic devices. In particular, the beam position...

    Oral

    A photon beam generated by the Insertion Device (ID) of a synchrotron light source can be contaminated by radiation from upstream and downstream bending magnets, leading to position measurement errors in blade-type monitors. The operation of the Korea-4GSR, which has extremely low emittance, is particularly sensitive to photon beam position variations, necessitating more accurate position...

    The small vacuum apertures in the 4th generation storage ring contribute significantly to beam instabilities, primarily caused by impedance. These instabilities are directly influenced by the bunch charge, which imposes a constraint on the maximum achievable beam current. The Korea-4th Generation Storage Ring (Korea-4GSR), currently under construction, aims to achieve a beam current of 400 mA....

    The RF cavities in the storage ring to compensate for the energy loss through synchrotron radiation have inevitable jitter as a technical limitation of the LLRF system. This jitter in phase and amplitude causes longitudinal oscillations of the electron beam stored in the storage ring, making it difficult to provide the synchrotron radiation reliably. With modern technology, phase and amplitude...

    Simulator for Free Electron Laser (FEL) realizes exploring non-linear phenomena between electron beams and undulators. There are some FEL codes for different purposes, but most popular code is GENESIS1.3 pursuing the averaged-frequency scheme which has fast calculation speed and can show time profiles of FEL as well as spectral features. To simulate real FEL, users have to consider various...

    ICABU WG2. Beam Physics, Diagnostics & Novel Techniques
    Oral

    Resonance islands are phenomena utilized in various storage rings to split or separate charged particle bunches. A new Hamiltonian model has recently been proposed to describe these phenomena [K. M. Nam et al., Revised Hamiltonian near third-integer resonance and implications for an electron storage ring, Phys. Rev. Accel. Beams (2024)]. However, the dynamics of these phenomena, particularly...

    The Rare-isotope Accelerator complex for ON-line experiment (RAON) is a heavy ion accelerator with a maximum beam power of 400 kW. The ion beam generated from the injector is accelerated in the SCL3 and then transmitted through the P2DT section to the KoBRA or NDPS laboratory. It is important to measure various beam parameters accurately not only for beam transmission without loss, but also as...

    Oral

    Laser wakefield acceleration (LWFA) is a method for accelerating electrons injected into a cavity created by the ponderomotive force resulting from the interaction between a femtosecond laser and low-density plasma. Significant research has been conducted on plasma generation for this purpose, and LWFA using metal ablation targets stands out for achieving high vacuum and high repetition rates...
