Physics data taking of OPERA, a long baseline neutrino oscillation experiment, has been successfully in progress since 2008 and a first tau neutrino candidate event has been found. Based on the techniques used in OPERA, we have studied a possible emulsion detector of next generation neutrino oscillation experiments to observe all the 6 types of neutrino/anti-neutrino charged current interactions. We have made a prototype of such a detector placed in a magnetic field and tested it with electron and hadron beams. As a result, we have found that it has sufficient accuracy for the electric charge sign measurement.

自2008年以来，长基线中微子振荡实验OPERA的物理数据采集工作取得了成功，首次发现了τ中微子候选事件，基于OPERA的技术，我们研究了下一代中微子振荡实验可能的乳胶探测器，以观测所有6种类型的中微子/反中微子带电电流相互作用。我们已经制作了一个放置在磁场中的这种探测器的原型，并用电子和强子束对其进行了测试。结果表明，它对电荷符号的测量具有足够的精度。
