DAEδALUS项目：原理和射束要求
The DAEδALUS Project: Rationale and Beam Requirements
摘要：
中微子物理学的重点是地下深处的巨大探测器。南达科他州的桑福德实验室将建造一个30万吨的水切伦科夫探测器，深度1500米，用于研究质量等级和CP破坏的μ子中微子振荡。这将被用于长基线实验（LBNE），从1300公里外的费米实验室检测几个GeV中微子。DAEδALUS合作组织还计划在距离300 kT探测器20公里的更近距离处建立几个中微子产生点，从停止的π介子中产生μ介子反中微子。与LBNE的互补性大大提高了结果，做这两个实验的热情正在上升。DAEδALUS需要0.8-1 GeV的加速器和mA质子束。距离300 kT探测器1.5、8和20 km的三个站点需要几个加速器。每台机器的成本必须低于现有兆瓦级质子机器的1/10。除了高功率和能量之外，束流参数是适度的。面临的挑战是可靠性，控制光束损失和最大限度地减少激活。正在研究的备选方案有：一个紧凑的超导回旋加速器;一个环形回旋加速器加速H2+（与剥离提取）;和一个堆叠回旋加速器与多达9个平面共享相同的磁轭和射频系统。
英文摘要：
Neutrino physics focuses on huge detectors deep underground. The Sanford Lab in South Dakota will build a 300 kiloton water-Cherenkov detector 1500 meters deep for muon neutrino oscillation studies of the mass hierarchy and CP violation. This will be used by the Long Baseline experiment (LBNE) detecting few GeV neutrinos from Fermilab, 1300 km away. The DAEδALUS Collaboration also plans several neutrino-production sites at closer distances up to 20 km from the 300 kT detector, producing muon antineutrinos from stopped pions. The complementarity with LBNE greatly enhances results, and enthusiasm is mounting to do both experiments. DAEδALUS needs 0.8-1 GeV accelerators with mA proton beams. Three sites at 1.5, 8 and 20 km from the 300 kT detector require several accelerators. The cost per machine must be below 1/10 of existing megawatt-class proton machines. Beyond high power and energy, beam parameters are modest. Challenges are reliability, control of beam loss and minimizing activation. Options being studied are: a compact superconducting cyclotron; a ring cyclotron accelerating H2+ (with stripping extraction); and a stacked cyclotron with up to 9 planes sharing the same magnet yoke and rf systems.
