摘要:

欧洲核子研究中心正在进行实验和理论活动,目的是研究甚高通量中微子源的可行性。在本方案中,高功率质子束(约4兆瓦)轰击产生π介子的靶。在受控的光学条件下收集π介子并衰变为μ介子。μ子被冷却并加速到50 GeV的最终能量,然后被注入衰变环,在那里它们在明确定义的能量和发射度条件下衰变。我们提出了整个方案中最具挑战性的部分,μ子捕获,电离冷却和μ子加速的第一阶段。不同的方案,他们的性能和技术挑战进行了比较。

英文摘要:

Experimental and theoretical activities are underway at CERN with the aim of examining the feasibility of a very-high-flux neutrino source. In the present scheme, a high-power proton beam (some 4 MW) bombards a target where pions are produced. The pions are collected and decay to muons under controlled optical condition. The muons are cooled and accelerated to a final energy of 50 GeV before being injected into a decay ring where they decay under well-defined conditions of energy and emittance. We present the most challenging parts of the whole scenario, the muon capture, the ionisation-cooling and the first stage of the muon acceleration. Different schemes, their performance and the technical challenges are compared.
