Green ILC

Abstract

The design of International Linear Collider (ILC) is based on the Superconducting RF (SRF) technology, which is more efficient than the normal conducting technology in terms of the energy consumption. However, still the total energy consumption of ILC (500 GeV) is 164 MW, which is much larger than those of existing accelerators in the world. In such a situation, the reduction of energy consumption in ILC, thus the efficient and sustainable design of ILC, is the crucial issue to realize it in the near future in a Japanese site. In order to challenge the issue, we organized a working group, so called “Green-ILC WG” in the Advanced Accelerator Association (AAA) in Japan, which involves 112 companies from industry and 42 organizations from academia. The Green-ILC WG is also collaborating with the international team of ILC. The activities are covering the studies on the efficient design of components, accelerator sub-systems, ILC-system, and even ILC-city. This presentation will report the current status of these studies.
