MERIT 实验旨在对基于 15-T 螺线管内的自由汞射流的目标系统进行原理验证测试，该系统能够维持高达 4 MW 的质子束功率。该实验于 2007 年秋季在 CERN 进行。我们描述了测试结果及其影响。正在讨论未来可能的机器的计划，这些机器可以提供多兆瓦束功率的质子束。这些强大光束的一个突出应用是产生适合研究重要物理问题的强次级光束。例子包括对罕见衰变过程和中微子振荡的研究。中微子工厂和 μ 子对撞机合作组织 [1] 提出了一个目标系统 [2, 3]，它将能够支持 4 MW 的质子束功率，目的是产生和收集强 μ 子束，最终用于存储环。该目标系统的核心由高Z、自由流动的液态汞射流组成，该射流在高场（15-20 T）螺线管的范围内拦截质子束。该系统的一个重要属性是液体射流靶可以替换为后续的质子脉冲。本文描述的实验旨在提供这一概念的原理验证演示。先前已报道过该实验的准备工作[4]。
The MERIT experiment was designed as a proof-of-principle test of a target system based on a free mercury jet inside a 15-T solenoid that is capable of sustaining proton beam powers of up to 4 MW. The experiment was run at CERN in the fall of 2007. We describe the results of the tests and their implications. Plans are being discussed for possible future machines which can deliver proton beams with multi-MW beam powers. A prominent application for these powerful beams will be to produce intense secondary beams suitable for investigating important physics issues. Examples include investigations of rare decay processes and neutrino oscillations. The Neutrino Factory and Muon Collider Collaboration [1] has proposed a target system [2, 3] which will be capable of supporting proton beam powers of 4 MW with the purpose of producing and collecting intense muon beams for eventual use in storage rings. The core of this proposed target system consists of a high-Z, free-flowing liquid mercury jet which intercepts the proton beam within the confines of a high-field (15-20 T) solenoid. An important attribute of this system is that the liquid jet target can be replaced for subsequent proton pulses. The experiment described in this paper was designed to provide a proof-of-principle demonstration of this concept. Preparations for this experiment have been previously reported [4].
