ILC accelerator status

The international linear collider (ILC) is a Higgs Factory, where electron-positrons are accelerated by the linear accelerators using Superconducting RF (SRF) cavities to 125 GeV. In 2013, the GDE, an international organization of researchers, already compiled the TDR. It is currently being studied under the International Development Team (IDT). Especially, from 2023, the ILC Technology Network (ITN), specifically under the IDT, will work on the development through international cooperation. This presentation will show an overview of the ILC and the recent developments under the ITN. First, an overview about the latest proposed Higgs factories of more than 250 GeV energy will be given. Second, we introduce the ILC accelerator, including the design, key technologies, accelerator systems. Finally, an detailed ongoing key technology developments, such as SRF cavities, nanobeam, and sources, for ILC project over the next few years will also be presented. We believe that these accelerator developments are not only crucial for ILC development but also for the improvements of future accelerators and various industrial and medical applications.
