Innovate for Sustainable Accelerating Systems

粒子加速器已经成为改善我们的健康、环境、安全和高科技能力的重要工具，以及揭示物理、化学、生物学的新的基本见解，并总体上使科学突破改善我们的生活。将粒子加速到更高的能量总是需要大量的能量。在一个能源可持续性至关重要的社会中，将能源消耗保持在尽可能低的合理水平对研究基础设施(RIS)和工业来说都是一个不可避免的挑战，这两个机构总共运营着40,000多个加速器。基于最先进的技术，欧洲目前和未来的加速器驱动的RI组合可能会发展到消耗德国年电力需求的1%。为了保持欧洲RIS的吸引力和竞争力，并促进欧洲的绿色交易，我们建议通过在该领域建立更好的合作来创新可持续加速系统(ISA)，以扩大、加快和扩大新型节能技术的开发和影响，以加速粒子的加速。对于许多前沿加速器来说，超导射频(SRF)系统是使能技术。ISAS将创新那些已被确定为SRF加速系统的共同核心并具有最大节能杠杆作用的技术，以最大限度地减少运营所有阶段的内在能源消耗。在加速器驱动的RIS领域，正在开发解决方案，以重新利用产生的余热，开发节能磁体，并在能源可用时按机会主义计划运营设施。ISAS项目的补充重点是SRF加速技术的能效。这将有助于在绿色和节能的21世纪保持20世纪加速器技术的巨大应用。

Particle accelerators have become essential instruments to improve our health, the environment, our safety, and our high-tech abilities, as well as to unlock new fundamental insights in physics, chemistry, biology, and generally enable scientific breakthroughs that improve our lives. Accelerating particles to higher energies will always require a large amount of energy. In a society where energy sustainability is critical, keeping energy consumption as low as reasonable possible is an unavoidable challenge for both research infrastructures (RIs) and industry, which collectively operate over 40,000 accelerators. Based on state-of-the-art technology, the portfolio of current and future accelerator-driven RIs in Europe could develop to consume up to 1% of Germany's annual electricity demand. With the ambition to maintain the attractiveness and competitiveness of European RIs and to enable Europe’s Green Deal, we propose to Innovate for Sustainable Accelerating Systems (iSAS) by establishing enhanced collaboration in the field to broaden, expedite and amplify the development and impact of novel energy-saving technologies to accelerate particles. For many frontier accelerators superconducting RF (SRF) systems are the enabling technology. iSAS will innovate those technologies that have been identified as being a common core of SRF accelerating systems and that have the largest leverage for energy savings to minimize the intrinsic energy consumption in all phases of operation. In the landscape of accelerator-driven RIs, solutions are being developed to reuse the waste heat produced, to develop energy-efficient magnets and to operate facilities on opportunistic schedules when energy is available. The iSAS project has a complementary focus on the energy efficiency of the SRF accelerating technologies. This will contribute to the vital transition to sustain the tremendous 20th century applications of the accelerator technology in a green and energy conscious 21st century.
