The project will comprise preparatory studies for the Deep Underground Neutrino Experiment DUNE, at the Long-Baseline Neutrino Facility LBNF, USA. Neutrinos are generated from a 1.2 MW proton beam at Fermilab, USA, and travel 800km to the Sanford Underground Research Facility. The beam is instrumented with two near and far detectors. The Far Detector is based around an active volume of 40k-tonne of liquid Argon, instrumented as a time projection chamber TPC. In order to reduce the data volume produced by the Far Detector over the 20 year lifespan of the experiment, the data acquisition system includes a data-selection system, or "trigger". This project will include development of trigger algorithms, and estimation of their performance with Monte-Carlo simulation. Trigger algorithms will also be deployed and characterised at the ProtoDUNE detector, an 800 tonne prototype of the future DUNE Far Detector, currently in operation at CERN. Finally, using data collected during Run 2 of ProtoDUNE in 2024, a measurement of pion-Argon cross-sections will be performed. This will focus on the charge-exchange process and will investigate use of machine learning algorithms to identify neutral pions in the liquid Argon TPC.

该项目将包括美国长基线中微子设施 LBNF 的深层地下中微子实验 DUNE 的准备研究。中微子由美国费米实验室的 1.2 MW 质子束产生，并传播 800 公里到达桑福德地下研究设施。光束配有两个近端和远端探测器。远距离探测器以 4 万吨活跃体积的液态氩为基础，配备时间投影室 TPC。为了减少远距离探测器在 20 年实验寿命期间产生的数据量，数据采集系统包括数据选择系统或“触发器”。该项目将包括触发算法的开发以及通过蒙特卡罗模拟评估其性能。触发算法也将在 ProtoDUNE 探测器上部署和表征，ProtoDUNE 探测器是未来 DUNE 远探测器的 800 吨原型，目前在 CERN 运行。最后，将利用 2024 年 ProtoDUNE 第 2 次运行期间收集的数据，对π介子-氩截面进行测量。该项目将重点关注电荷交换过程，并将研究使用机器学习算法来识别液态氩 TPC 中的中性介子。
