摘要
T2K(东海至神冈)是日本的一个长基线中微子实验,旨在研究中微子振荡的各种参数。一个近探测器复合体(ND280)位于产生靶下游 280 米处,用于在任何振荡发生前测量中微子束参数。ND280 的测量结果被用来预测距离 295 公里处的超级神冈探测器中微子的数量和能谱。远探测器(水)与近探测器(闪烁体、碳氢化合物)之间靶材料的差异,导致了振荡分析中主要的非抵消性系统误差。为减少这一误差,开发了一种新型的水-网格-闪烁体探测器(WAGASCI)。一个磁化铁中微子探测器(Baby MIND)将用于测量带电电流相互作用产生的出射 μ 子的动量和电荷鉴别。Baby MIND 模块由磁化铁板和长塑料闪烁体条组成,这些闪烁体条两端通过波长位移光纤和硅光电倍增管读出。已开发出前端电子学板,用于执行闪烁体条信号的读出和数字化。探测器元件已利用宇宙射线和在 CERN 的 PS 束流中进行了测试。本文展示了所获得的结果。
