Better timing precision for Hyper-Kamiokande – BERTHA

Submission summary

The BERTHA project aims at developing the clock distribution and time synchronization system for the long-baseline neutrino oscillation experiment called Hyper-Kamiokande (HK) in Japan.
During this 4-year program, we will pursue a R&D program to produce at LPNHE clock distribution prototypes which will be tested at the neutrinos observatory Super-Kamiokande and at the Water Cherenkov Test Experiment (WCTE) at CERN.
We also intend to build the time generation system that will be used in the HK far detector.
We will also have a strong impact on the activities related to the analysis of data collected by WCTE and produce a better understanding of Cherenkov light emission processes in water.
Finally, within the BERTHA project, a comprehensive computing and data management model will be implemented before the start of the HK data taking period.
The funds of this proposal will allow us to hire a postdoc to carry this work, analyze the data produced by WCTE and also to contribute to the impact studies of the clock distribution system on Hyper-Kamiokande using the feedback collected from Super-Kamiokande and WCTE and the computing model implementation.
This project will have a strong impact on the Hyper-Kamiokande experiment and the future of the French contribution to this promising experiment.
