花生实验旨在研究费米实验室的努米中微子束。探测器使用了一种混合技术，由核乳剂和闪烁体跟踪器组成。乳胶膜用作微量跟踪装置，并与用作被动材料的铅板交错。该探测器被设计成精确地重建中微子相互作用的拓扑结构，从而测量对截面的不同贡献。我们给出了147个中微子相互作用的完整重建和分析，并测量了在Numi中微子束能量下准弹性、共振和深非弹性对总带电电流截面的贡献。这项技术可以应用于未来中微子装置的束流监测，本文给出了它的原理证明。
The PEANUT experiment was designed to study the NuMi neutrino beam at Fermilab. The detector uses a hybrid technique, being made of nuclear emulsions and scintillator trackers. Emulsion films act as a micrometric tracking device and are interleaved with lead plates used as passive material. The detector is designed to precisely reconstruct the topology of neutrino interactions and hence to measure the different contributions to the cross section. We present here the full reconstruction and analysis of 147 neutrino interactions and the measurement of the quasi-elastic, resonance and deep-inelastic contributions to the total charged current cross section at the energies of the NuMi neutrino beam. This technique could be applied for beam monitoring in future neutrino facilities, and this paper shows its proof-of-principle.
