能源前沿加速器提供了执行高精度测量的强大工具，证实了物理学的基础知识并拓宽了新的研究视野。此类机器由圆形加速器或直线加速器驱动。圆形机器的质心 (CM) 能量值达到 200 GeV（对于轻子）及以上，会经历束流能量损失和质量稀释，例如，由于同步加速器辐射，限制了可实现的总体 CM 能量，并且需要恒定的能量补充来补偿损失和束质量稀释。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。这可以通过碰撞光束的质量来部分补偿。在这项工作中，我们提出了一种基于“非发射”、低能量存储环和能量回收直线加速器合并的圆形直线加速器的新颖设计。我们建议使用最近考虑的双轴不对称腔来实现此类系统的运行，特别是从废高强度光束中回收能量。在 SNOWMASS-2021 计划的范围内，该机器有望用于达到高能物理的终极能量前沿，并驱动下一代光源。圆形和线性系统的合并以及双轴腔的应用应该能够保持高光束质量、高亮度和高能源效率，同时提供灵活的能源管理并为降低运行成本提供明显的机会。我们注意到，论文中显示的数字仅供说明之用，可以进一步改进。
Energy-frontier accelerators provide powerful tools performing high precision measurements confirming the fundamentals of the physics and broadening new research horizons. Such machines are either driven by circular or linear accelerators. The circular machines, having the centre-of-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, while offering a flexible energy management and 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.
