我们总结了目前的状态，μ子加速的概念，旨在未来的中微子工厂。这些研究的主要目的是通过探索冷却系统的复杂性和加速器复合体的可接受性之间的相互作用来降低总体成本，同时保持性能。为了确保短寿命的μ子有足够的存活，加速必须在高平均梯度下发生。对大的横向和纵向接受度的需要将加速系统的设计驱动到初始低的RF频率，例如，325 MHz，然后随着横向尺寸随着能量的增加而缩小，其增加到650 MHz。在这些频率下的高梯度正常传导RF腔需要极高的峰值功率RF源。因此，超导RF（SRF）腔被选择。我们考虑了两种用于可分级中微子工厂的加速μ子束的具有成本效益的方案：探索所谓的“两用”直线加速器概念，其中相同的直线加速器结构用于加速H−和μ子，或者，基于多通（4.5）“狗骨”RLA的SRF高效设计，可扩展到多通FFAG-样弧。
We summarize the current state of a concept for muon acceleration aimed at a future Neutrino Factory. The main thrust of these studies was to reduce the overall cost while maintaining performance by exploring the interplay between the complexity of the cooling systems and the acceptance of the accelerator complex. To ensure adequate survival for the short-lived muons, acceleration must occur at high average gradient. The need for large transverse and longitudinal acceptances drives the design of the acceleration system to an initially low RF frequency, e.g., 325 MHz, which is then increased to 650 MHz as the transverse size shrinks with increasing energy. High-gradient normal conducting RF cavities at these frequencies require extremely high peak-power RF sources. Hence superconducting RF (SRF) cavities are chosen. We consider two cost effective schemes for accelerating muon beams for a stageable Neutrino Factory: exploration of the so-called “dual-use” linac concept, where the same linac structure is used for acceleration of both H− and muons and, alternatively, an SRF-efficient design based on a multi-pass (4.5) “dogbone” RLA, extendable to multi-pass FFAG-like arcs.
