作为T2K和Hyper-Kamiokande实验的离轴近探测器的WAGASCI探测器

The WAGASCI detector as an off-axis near detector of the T2K and Hyper-Kamiokande experiments

Benjamin Quilain

摘要:

在T2 K和未来的Hyper-Kamiokande实验中寻找CP破坏时,减少目前的系统不确定性是至关重要的。目前的T2 K近场探测器ND 280在$ν_{e}$出现通道中将中微子束和截面模型的不确定性从$11.9\%$降低到$5.4\%$。这些剩余不确定度主要来自于ND 280本身的局限性,这是由于ND 280在目标材料和与远探测器的角度接收方面的差异造成的。为了显示T2 K第二阶段和Hyper-Kamiokande实验中的CP破坏的证据(随后的观测),本文提出了ND 280探测器的升级。它使用由时间投影室包围的3D网格闪烁体结构,以重建具有$\sim 4π$接受度的粒子。

英文摘要:

In the search for CP violation at the T2K and future Hyper-Kamiokande experiments, it is crucial to reduce the present systematic uncertainties. The current T2K near detector, ND280, reduces the uncertainties coming from the neutrino beam and cross-section models from $11.9\%$ to $5.4\%$ in the $ν_{e}$ appearance channel. These residual uncertainties mostly come from intrinsic limitations of ND280 due to its difference in target material and angular acceptance with the far detector.\\ In order to show evidence (subsequently observation) of the CP violation in the T2K phase-II and Hyper-Kamiokande experiments, this paper proposes an upgrade of the ND280 detector. It uses a 3D grid scintillator structure surrounded by Time Projecting Chambers in order to reconstruct particles with $\sim 4π$ acceptance.
