197. Sustainability Studies for ILC and CLIC

Benno List (DESY Hamburg)

16/05/2023, 15:30

Sustainability has become a prioritized goal in planning and implementation of future large accelerators, where ILC and CLIC have been collaborating to study novel design and technology solutions to address power efficiency and reduce the environmental impact of the facilities. Recent activities include studies on high efficiency components and life cycle assessments of civil engineering and...

198. High Efficiency Klystrons project at CERN: Status and u

Igor Syratchev (CERN)

16/05/2023, 15:50

Klystron is a key element of almost all particle accelerators. The High Efficiency Klystron Project at CERN is targeted to develop, fabricate and commission the new devices with improved efficiency for various particle accelerators and other applications. This activity is conducted in a close collaboration with industrial partners and scientific Labs. We will review the status and ongoing...

71. Linear Collider Carbon Assessments: A Life Cycle Assessment of the CLIC and ILC Linear Collider Feasibility Studies

Sustainability

Oral

Linear colliders are a promising technology for exploring the frontiers of particle physics. However, the construction and operation of these large-scale scientific instruments have significant environmental impacts, particularly in terms of carbon emissions. In this talk, we present a comprehensive life cycle assessment (LCA) of both the Compact Linear Collider (CLIC) and International Linear...

199. Green ILC Concept

Masakazu Yoshioka (Iwate University, Iwate Prefectural University), Masakazu Yoshioka (Iwate University, Iwate Prefectural University)

16/05/2023, 16:30

The Kitakami Highlands of Iwate Prefecture, where the ILC candidate site is located, is served by Tohoku Electric Power Co. The company's CO2 emission coefficient for FY2021 is 0.483 kg- CO2/kWh. This is about twice the figure for Europe. The Japanese government has set a goal of achieving carbon neutrality by 2050. This report presents a scenario in line with that policy.

200. Permanent magnet technology for sustainable accelerators

Ben Shepherd (STFC Daresbury Laboratory)

16/05/2023, 16:50

Permanent magnet technology is a path to reducing energy usage and carbon emissions for accelerator facilities. This talk presents some examples of where PM technology has been adopted in place of electromagnets, and highlights the advantages and disadvantages of this technology.

201. IHEP high efficiency, high power klystron development

Zysheng Zhou (IHEP, China)

16/05/2023, 17:10

After the discovery of the Higgs boson at LHC, Chinese scientists have planned to build a “Great Collider,” which is a next-generation multinational particle accelerator research facility proposed as a circular electron-positron collider (CEPC) and a super proton–proton collider (SPPC). The CEPC synchrotron radiation power is supposed to be more than 60MW. Institute of High Energy Physics...

202. Basic research using synchrotron radiation and commercialization of waste heat recovery technology from ILC

Goh Mitoya (Higashi Nihon Kidenkaihatsu Co., Ltd., Japan)

16/05/2023, 17:30

We are conducting research to recover and utilize the energy discharged from the ILC facility under the concept of Green ILC. As the candidate site for construction, Iwate Prefecture, which has the Kitakami site, is 80% mountainous, and an effective model for heat energy circulation and utilization that suits the regional characteristics is required. Therefore, we aim to commercialize an...

203. Town planning in the vicinity of ILC candidate site as a regional company

Masahiko Kondo (Kondo Equipment Corporation, Japan)

16/05/2023, 17:40

: In cooperation with Iwate University, Iwate Prefectural University, and several private companies, we are constructing a 20-hectare facility within a 40-minute drive time and 30-40 km from the ILC candidate site to provide residential facilities and outdoor activities to promote health and familiarity with nature. This facility can serve as a model for town planning where ILC-related people...
