摘要:

长基线中微子实验(LBNE)将利用位于费米实验室的中微子束线设施。该设施的设计目的是将一束中微子瞄准位于南达科他州的探测器。中微子的产生有三个步骤。首先,来自主注入器的质子击中固体目标并产生介子。然后,带电介子被一组聚焦喇叭聚焦到衰变管中,朝向远处的探测器。最后,进入衰变管的介子衰变为中微子。该设施的参数是由物理目标的混合物,该设施的蒙特卡罗建模,并通过在费米实验室操作NuMI设施所获得的经验。初始射束功率预计为~700 kW,然而,选择了一些参数以能够处理2.3 MW的射束功率。LBNE中微子束通过考虑许多价值工程建议对初始设计进行了重大修改,并描述了当前的设计。

英文摘要:

The Long Baseline Neutrino Experiment (LBNE) will utilize a neutrino beamline facility located at Fermilab. The facility is designed to aim a beam of neutrinos toward a detector placed in South Dakota. The neutrinos are produced in a three-step process. First, protons from the Main Injector hit a solid target and produce mesons. Then, the charged mesons are focused by a set of focusing horns into the decay pipe, towards the far detector. Finally, the mesons that enter the decay pipe decay into neutrinos. The parameters of the facility were determined by an amalgam of the physics goals, the Monte Carlo modeling of the facility, and the experience gained by operating the NuMI facility at Fermilab. The initial beam power is expected to be ~700 kW, however some of the parameters were chosen to be able to deal with a beam power of 2.3 MW. The LBNE Neutrino Beam has made significant changes to the initial design through consideration of numerous Value Engineering proposals and the current design is described.
