Photogrammetry and water monitoring for Hyper-K

The next generation neutrino experiments like Hyper-Kamiokande will have statistical power, but the presence of detector systematics will limit the discovery potential of the experiments.
The uncertainties due to construction tolerances, support frame shift from PMT buoyancy, and the source deployment system, combined with uncertainties in PMT angular response, and position-dependent water quality, can limit the precision of our final measurements. Through the application of photogrammetry, position, and potentially direction, of each PMT and deployed calibration sources can be calibrated, independently from all other degenerate detector parameters including those mentioned above. Furthermore, mitigating the water-related uncertainties requires R&D of water purification systems, water quality measurement apparatuses, and ultra-pure and gadolinium (Gd) loaded water compatibility soak testing for future detector components. Through this internship at Kavli IPMU, I plan to contribute to the development of these novel techniques for controlling the detector systematics that are crucial for the high significance discoveries of Hyper-Kamiokande.
