The neutrino activity would permit a comprehensive neutrino science program over a decade or more that would include the precision measurement of neutrino mass differences and oscillation parameters, plus very possibly the measurement of matter-antimatter asymmetries (CP violation) that could connect the neutrino sector to leptogenesis as a source of the matter-antimatter asymmetry of the universe.

有奖励

中微子活动将允许超过10年或更多，其中将包括大量的中微子振荡的分歧和参数，加上很可能是物质的测量，反物质不对称（CP破坏），可以连接中微子部gate的精确测量中微子科学项目全面leptogenesis作为物质来源，反物质宇宙的不对称性。

The Neutrinos at the Main Injector (NuMI) beam is the most powerful neutrino beam that has ever operated, with up to 0.3 MW of proton beam power directed at the NuMI target. The Main Injector Neutrino Oscillation Search (MINOS) collaboration operates two detectors, one at a distance of 730 km in the Soudan mine which are necessary to disentangle the effects of neutrino interactions with matter from the possible effects of CP violation. The sensitivity of an experiment is proportional to (beam power) x (detector mass) x (detector efficiency). Fermilab is increasing the NuMI beam intensity through a series of steps to a total beam power of 0.4 MW on target by 2010. The primary modifications to the complex include conversion of the Recycler Ring from an antiproton storage ring to a proton accumulator ring, and the conversion of the Antiproton Accumulator ring to a proton momentum stacking ring. Such conversions would allow Fermilab to continue operations of the neutrino program at the forefront of the field through the middle-to-end of the next decade. In parallel we continue to pursue a modest R&D program aimed at developing highly efficient techniques for very high intensity proton acceleration based on superconducting rf technologies. Such technologies could provide a basis for further long term performance enhancements if called for.

谢谢啊  好心人啊 要是上面那段呢

好强大的一段

NuMI束是最强的中微子束，有高达0.3MW的质子束功率直接传到NuMI 靶上，还未被控制（operated）. MINOS加载2个探测器，一个在明尼苏达州铁矿井下730km，这是脱离CP破坏造成的质子互相影响必要的。这个实验的敏感度比例为质子束功率x 探测器质量x 探测器效率。在2010年的时候费米实验室将会增加NuMI粒子束的强度，通过一系列的步骤使靶上的功率为0.4MW.这项复杂工程最首要的修改包括将“回收环”从反质子存储环改成质子[屏蔽]环和将反质子[屏蔽]环改成质子动量垛堆环。这些修改可以使费米实验室在未来10年可以继续在这个领域的前沿研究中微子项目。我们将继续一个严谨的R&D 项目，采用超传导性的射频技术研发高效能的仪器，为高强度质子加速。这些技术可以为更长期的研究提供基础。

背景资料
一个中微子有多重？在明尼苏达州北部一个报废的铁矿井深处，安放着一个6000吨的探测器，等待揭开宇宙的最大奥秘之一。该探测器是将为Minos（Main　Injector
　　Neutrino　　Oscillation　Search）————美国费米实验室的物理学家们对中微子所进行的最新研究————建造的两个当中的一个。
　　中微子是宇宙中最普通的粒子当中的一种————每秒钟就有数以十亿计的中微子穿过每平方英寸的空间。虽然据悉它们的质量极小，而且稍纵即逝，但是它们的数量本身就使一些科学家相信，中微子是占据宇宙质量大约95％的神秘的暗物质的来源。
　　明尼苏达州的Minos探测器将设法捕捉从450多英里以外向其发射的一束中微子。由于中微子很少与其周围环境相互作用，所以大约将只有其中的1500个中微子与探测器发生实际碰撞。这些中微子将为科学家们打开一扇独特的窗户，使之看到暗物质的真实本质。
