The proposed sub-tunnels are considered necessary for the construction, installation and operation of the BDS and beam dump. It would also provide access to facilities such as a laser room for polarimetry, a preparation room for beam dump experiments and magnet power supply rooms.
A constantly updated 3D CAD model will also be presented.
The development schedule of the ILC Central Area affects the assembly and installation schedule of the detectors, which in turn significantly impacts the overall ILC construction schedule. We conducted a detailed study of the process required for constructing the ILC at the Kitakami site in Japan, from the start of construction until the assembly of detectors can be started. The results of...

The design of the next generation of linear colliders demands a renewed, high-performance, integrated set of simulation codes. We present the Beam, pLasma & Accelerator Simulation Toolkit (BLAST), which includes legacy accelerator codes such as Impact-T, Impact-Z, Warp and Posinst, as well as a renewed generation of accelerator codes such as ImpactX, WarpX and HiPACE++. The new codes, born out...
The International Linear Collider (ILC) is among the most mature designs for a next-generation linear electron-positron collider. Plasma-based accelerators have also been proposed to reach the 10 TeV COM level further in the future. A key challenge in these types of machines is preserving the luminosity at the target value, mitigating the potentially detrimental effects of disruption,...
I will report on a comparison of beam-strahlung backgrounds at the ILC and FCCee, with an emphasis on the TPC and Vertex detector. The different MDI designs and beam timing structures at the two colliders have some dramatic effects on detector backgrounds.
Beam-beam interactions constitute an important source of background at any electron-positron ($e^{+}e^{-}$) collider, generating the so-called beam-induced background (BIB), with important implications for the design and optimization of detectors at these machines and, ultimately, their physics reach. In this talk, we will present the latest results on the evaluation of the BIB at the Cool...
The Hybrid Asymmetric Linear Higgs Factory (HALHF) proposes a shorter and cheaper alternative for a future Higgs factory. The design includes a 500 GeV electron beam accelerated by an electron-driven plasma wake-field, and a conventionally-accelerated 31 GeV positron beam. Assuming plasma acceleration R&D challenges are solved in a timely manner, the asymmetry of the collisions brings...
Following the mid-term review in 2023, the Future Circular Collider (FCC) feasibility study at CERN continues towards the European Strategy for Particle Physics 2025. This talk will cover the main updates, current progress of the civil engineering design and the status of the geotechnical site investigations.
The machine-detector interface (MDI) issues are one of the most complicate and challenging topics at the Circular Electron Positron Collider (CEPC). Comprehensive understandings of the MDI issues are decisive for achieving the optimal overall performance of the accelerator and detector. The machine will operate at different beam energies, therefore, a flexible interaction region design will be...
