The first task of the fellow was working on the software for the WAGASCI near detector for the T2K experiment. This involved taking ownership of the software project as the previous maintainers had left the T2K collaboration and ensuring that the latest changes were incorporated into the code in a consistent manner. He also conainterised all code packages associated with this project to ensure that the code worked across platforms and could be run at different computing clusters around the world.The next related task was MC production which involved running all of the code required to simulate the full chain of events in the detector. The organisation and containerisation of the code achieved in the first step greatly aided this task and provided new simulation samples that can be used in future studies.He wrote documentation which was distributed to all collaborators on how this task can be achieved, ensuring that this institutional knowledge will be preserved within the experiment.The fellow developed a new selection with which to perform a new joint cross section analysis using data from both the ND280 and WAGASCI near detectors. This will be the first joint analysis using these detectors and will have a sensitivity greater than that which either individual detector could achieve. This involved developing new software tools to perform data analysis on both detector data sets and will have future value as a path to further joint analyses.The fellow also travelled to JPARC to participate in data taking activity.

该研究员的第一个任务是为 T2K 实验的 WAGASCI 近探测器开发软件。这涉及到获得软件项目的所有权，因为之前的维护者已经离开了 T2K 协作，并确保最新的更改以一致的方式合并到代码中。他还对与该项目相关的所有代码包进行了容器化，以确保代码可以跨平台运行，并且可以在世界各地的不同计算集群上运行。下一个相关任务是 MC 生产，其中涉及运行模拟全链所需的所有代码检测器中的事件。第一步中实现的代码的组织和容器化极大地帮助了这项任务，并提供了可在未来研究中使用的新模拟样本。他编写了有关如何实现此任务的文档，并将其分发给所有合作者，以确保该机构知识将在实验中保留。该研究员开发了一种新选择，可使用 ND280 和 WAGASCI 近探测器的数据执行新的联合横截面分析。这将是使用这些探测器的首次联合分析，其灵敏度将高于任何单个探测器所能达到的灵敏度。这涉及开发新的软件工具来对两个探测器数据集进行数据分析，并且作为进一步联合分析的途径将具有未来的价值。该研究员还前往 JPARC 参加数据采集活动。
