摘要:

能源前沿加速器提供了强大的工具,可以进行高精度测量,确认物理学的基础知识,并拓宽新的研究视野。这种机器由环形加速器或直线加速器驱动。具有达到200 GeV(对于轻子)和更高的中心质量(CM)能量值的圆形机器例如由于同步辐射而经历射束能量损失和质量稀释,从而限制了可实现的总CM能量并且需要恒定的能量补充以补偿损失和射束质量稀释。线性对撞机克服了这些限制,而产生高平均电流束的有限能力限制了亮度。这部分地由碰撞光束的质量补偿。在这项工作中,我们提出了一种新的设计的圆直线加速器的基础上合并的“非发射”,低能量存储环和能量回收直线加速器。我们建议使用最近考虑的双轴非对称腔,使这样一个系统的操作,特别是能量回收用过的,高强度的光束。在SNOWMASS-2021计划的范围内,这台机器可能被用于达到高能物理学的终极能源前沿,以及驱动下一代光源。圆形和线性系统的合并,以及双轴腔的应用,应该允许保持高光束质量,高亮度和高能量效率-“两全其美”。它还提供了灵活的能源管理,为降低运行成本提供了明确的机会。我们注意到,文件中显示的数字是为了说明目的,可以进一步改进。

英文摘要:

Energy-frontier accelerators provide powerful tools performing high precision measurements confirming the fundamental of the physics and broadening new research horizons. Such machines are either driven by circular or linear accelerators. The circular machines, having the center-mass (CM) energy values reaching 200 GeV (for leptons) and above, experience beam energy loss and quality dilution, for example, due to synchrotron radiation, limiting the overall CM energy achievable and requiring a constant energy top-up to compensate the loss and the beam quality dilution. Linear colliders overcome these limitations, while the finite capabilities of generating high average current beams limits the luminosity. This is partially compensated by the quality of the colliding beams. In this work, we suggest a novel design of circular-linear accelerator based on the merging of the "non-emitting", low-energy storage rings and energy recovery linear accelerators. We suggest using the recently considered dual-axis asymmetric cavities to enable the operation of such a system, and in particular the energy recovery from spent, high-intensity beams. The machine considered, under the scope of the SNOWMASS-2021 initiative, can be potentially used to reach ultimate energy frontiers in high-energy physics as well as to drive next generation light sources. The merging of circular and linear systems, and applications of dual axes cavities, should allow the maintaining of high beam quality, high luminosity, and high energy efficiency - "The Best of Both Words". It also offers a flexible energy management, opening clear opportunity for reducing the running cost. We note that the numbers shown in the paper are for illustration purpose and can be improved further.
