Quick recap

This meeting focused on project progress updates and deliverables that was originally scheduled to end in June. Kazuhiro emphasized the need for team members to provide plans and timelines for completing their simulation papers, optical and LArTPC work, and datasets by the end of August, noting that people were forgetting to submit required papers. Junjie reported discussing a paper with Sam and confirmed they would meet the August deadline. Yifan explained that their paper was still missing key components related to positional shift and calibration parameters, with work ongoing on two different approaches. Zhenxiong reported checking and verifying previous code without making changes, planning to make a pull request soon, and noted that beam data analysis would take several more weeks. Riya provided updates on Nahuel's implementation of a SIREN for water transparency in Lucid and discussed plans to use Monte Carlo simulations with SK software as input for fitting. Ryo reported no specific updates for the week but mentioned attending a WCTE Efficiency meeting where they discussed WCSim simulation updates and the need to decide on data-driven distributions. The conversation ended with updates about Ryotaro joining the TRIUMF group for LED single PE analysis and continuing work on Lucid implementation.

Next steps

Junjie’s

• Work on the paper with Sam and provide milestones and progress updates, aiming for completion by end of August.

Riya

• Create Monte Carlo simulation events using SK software and use them as input to Lucid for fitting and comparison with SuperK.
• Contact Titouan to inquire about the PMT response siren branch and implementation status in Lucid.

Ryo

• Update the current reference waveform following comments from Nick, and await data analysis for further MDT updates.
• Coordinate with Ryotaro to continue working on Lucid and LED implementation during his stay at TRIUMF.

Yifan

• Incorporate positional shift into the paper and aim for a tight schedule, with progress updates before end of August.

Zhenxiong

• Submit a pull request for the code changes and summarize reconstruction results using real cosmic muon data; process beam data and rerun reconstruction in the coming weeks.

Summary

Project Deliverables Deadline Extension

Kazu discussed the project deliverables that were defined at a previous workshop, including simulation papers, optical and alert TPC papers, and datasets. He suggested extending the deadline from the end of June to the end of August due to current workload, noting that people may have just forgotten. Kazu clarified that while there is no specific reporting duty assigned to him, these deliverables should be tracked for future accountability.

Research Paper Progress Updates

Junjie discussed a paper with Sam and confirmed they would work on it with a timeline ending in August. Kazuhiro requested more detailed reporting on milestones and progress for future updates. The discussion also touched on separate papers by Omar and Ivan targeted for the end of June.

Research Progress and Updates Meeting

Yifan reported progress on incorporating positional shift into their paper, with two approaches being explored and expected completion by end of August. Kazuhiro emphasized the need for a tight schedule and faster completion. Zhenxiong updated that he had double-checked code and would make a pull request soon, while also planning to summarize reconstruction results using real data. Riya discussed implementing a siren for water transparency in Lucid and plans to create Monte Carlo simulations using SK software. Ryo reported on a WCTE efficiency meeting where they discussed updating WCC simulation and reference waveforms, though some decisions depend on data analysis. Patrick noted that the TRIUMF group expressed interest in exploring Cider and Lucid but lacks personnel to commit to the work.

Team Work Schedule and Tasks

Patrick and Ryo discussed a team member's work schedule from July to September and their current busy status. Patrick suggested the team member continue working on LED Single PE analysis and Lucid implementation for calibration analysis to ensure continuity in their work. No additional topics were raised before the conversation ended.
