Opaque detectors are a recently proposed novel detector concept where an opaque scintillator aligned with wavelength-shifting fibers is used to enable the discrimination of electron neutrinos and antineutrinos with a rather low energy threshold. In this work, we investigate the potential effects of the enhanced detection capabilities of the opaque detectors in accelerator neutrino experiments. Focusing on the energy threshold, energy resolution, detection efficiency and background suppression in the analysis of electron-like events, we determine whether using opaque detectors could lead to improvements in the CP violation and light sterile neutrino searches in the future accelerator neutrino experiments. We also identify the minimum requirements for the opaque detectors to reach the designated physics goals in the simulated experiments. We find that a 75.6% fraction of ${\delta }_{\mathrm{\text{CP}}}$ values could be reached for CP violation discovery by 3$\sigma$ confidence level or better when opaque detectors of 120 kton and 130 kton fiducial masses are used together with neutrino beams from J-PARC and MOMENT, respectively, whereas near detectors placed about 250 m from sources are sufficient to exclude the gallium anomaly at 2$\sigma$ confidence level.

加速器中微子实验中不透明探测器的前景和要求

不透明检测器是最近提出的一种新颖的检测器概念，其中将不透明的闪烁体与波长转换纤维对准，用于以较低的能量阈值来区分电子中微子和反中微子。在这项工作中，我们调查了加速器中微子实验中不透明检测器增强检测能力的潜在影响。重点关注类电子事件分析中的能量阈值，能量分辨率，检测效率和背景抑制，我们确定在未来的加速器中微子实验中，使用不透明检测器是否可以改善CP违规和轻度无菌中微子搜索。我们还确定了不透明探测器在模拟实验中达到指定物理目标的最低要求。${\delta }_{\mathrm{\text{CP}}}$ CP违规发现可以达到3的值$\sigma$ 当分别使用120 kton和130 kton基准质量的不透明探测器与来自J-PARC和MOMENT的中微子束一起使用时，置信水平或更高，而距源约250 m的近探测器足以排除2处的镓异常$\sigma$ 置信度。
