## Preparation of the Hyper-Kamiokande experiment for precise measurements of neutrino oscillation parameters

Title: Preparation of the Hyper-Kamiokande experiment for precise measurements of neutrino oscillation parameters

Supervisor: Boris Popov

Co-supervisor: Mathieu Guigue

Team: Asymétrie Matière-Antimatière ; group T2K

Description :

Hyper-Kamiokande is a next generation long-baseline neutrino oscillation
experiment that will be built in Japan. One of the main physics goals of
the experiment is the discovery of CP violation in the lepton sector. Moreover
Hyper-Kamiokande will be the most sensitive detector to proton decay
and will be an observatory for neutrinos from astrophysical sources,
such as supernovae neutrinos. The project has been recently approved in Japan
and the construction will be launched in April 2020.
The experiment will be based on a huge Water Cherenkov detector equiped with
photomultiplies (PMTs) of different types: large 50’’ PMTs developed by
Hamamatsu (Japan) and so-called multi-PMT modules made of several small 3’’
PMTs, currently being tested with the help of an existing water tank in Paris
(Memphyno setup).
The Hyper-Kamiokande detector will be exposed to an (anti)neutrino beam
produced at the J-PARC accelerator. It will also register interactions
of atmospheric and solar neutrinos.
The physics part of the thesis will be mainly devoted to sensitivity studies
for combined analysis of accelerator, atmospheric and solar neutrinos,
informed by existing data from T2K and Super-Kamiokande experiments.
The technical part of this work will be devoted to a design and construction
of a clock distribution and synchronization system for PMTs. This system
with prototypes developed at LPNHE can be tested within the Memphyno setup
and in the framework of a planned test experiment at CERN.

Work location: LPNHE, Paris

Possible trips: Tokai (Japon) and CERN, Geneva
