论文摘要
抗毒剂能量的MEV区域对于物理研究和监测核不增殖具有特殊意义。尽管液体闪烁探测器通常用于检测反β衰减（IBD），但最近已提出使用液体有机时间投影室检测到它，这可以允许对IBD最终状态的粒子轨迹进行全面重建。我们介绍了对预期签名的首次全面模拟研究。他们的明确签名可以使用有关所有最终状态颗粒的能量，位置和方向的信息来最小化对电子抗肿瘤的检测。我们表明，正电子轨道反映了抗神经侵的顶点。它也可以用于确定初始中微子能量。此外，我们研究了通过中子诱导的质子后坐力的能量沉积以逐个事件重建抗肿瘤方向的可能性。我们的模拟表明，这可能是一种有前途的方法，应该通过检测器原型实验进一步研究。
The MeV region of antineutrino energy is of special interest for physics research and for monitoring nuclear nonproliferation. Whereas liquid scintillation detectors are typically used to detect the Inverse Beta Decay (IBD), it has recently been proposed to detect it with a liquid-organic Time Projection Chamber, which could allow a full reconstruction of the particle tracks of the IBD final state. We present the first comprehensive simulation-based study of the expected signatures. Their unequivocal signature could enable a background-minimized detection of electron antineutrinos using information on energy, location and direction of all final state particles. We show that the positron track reflects the antineutrino's vertex. It can also be used to determine the initial neutrino energy. In addition, we investigate the possibility to reconstruct the antineutrino direction on an event-by-event basis by the energy deposition of the neutron-induced proton recoils. Our simulations indicate that this could be a promising approach which should be further studied through experiments with a detector prototype.
