Hyper-Kamiokande is a long-range neutrino oscillation experiment, under construction in Japan with a planned start of data collection in 2027. This experiment aims at imposing strong constraints on CP symmetry violation in the lepton sector as well as at producing accurate measurements of the oscillation parameters. The program of Hyper-Kamiokande is very rich, covering other topics of particle physics such as the decay of the proton or the search for sterile neutrinos and also multi-messenger astrophysics with the detection of the explosion of supernovae.
A new far detector with a larger fiducial volume than the Super-Kamiokande detector is under construction to increase the number of neutrinos detected. This new detector will have its detection electronics under water as close as possible to the photomultipliers (PMTs). All the signals coming from the 20,000 PMTs will have to be synchronized within the detector for the reconstruction of the Cherenkov rings, but also with astrophysics experiments around the world thanks to GPS signals. The LPNHE is in charge of the production of such a system. The amount of collected data will be consequent and the storage at the Computing Center of Lyon will be used.
The contract is funded by the JCJC "BERTHA" project of the ANR (French National Research Agency) for a period of three years and will cover the project deliverables. Travel expenses to Japan (especially for collaboration meetings and on-site testing) and participation in international conferences are covered by the project budget.


The successful candidate should work on the time generation and clock distribution system for the Hyper-Kamiokande distant detector and on the associated physics studies (time of flight, multi-messenger astrophysics), in order to prepare the installation and the data collection by the new distant detector. Depending on his/her tastes, contributions to HK computing may be made.
In addition, the candidate will contribute to the T2K experiment through shifts at the ND280 near detector and to the analysis of existing data for future analysis with the HK experiment.
The postdoctoral contract is funded by the ANR for two years, renewable for one year. The start date of the contract is October 1, 2022, but a later date can be considered.


The candidate must have a PhD degree (or equivalent) in particle physics or astrophysics. Good programming skills (C++, ROOT, python) are required. Knowledge of temporal signal processing and a background in experimental and data analysis is desired. Experience in neutrino oscillation analysis is desired but not required.
The addition to your application of a summary of previous scientific activities and a letter of motivation, and two or three letters of reference will be appreciated.

Work Context

The LPNHE is a joint research unit of 160 people whose research is mainly experimental in particle and astroparticle physics. It is involved in major international collaborations in the fields of particle physics, astroparticles and cosmology. Currently, the LPNHE Neutrinos group is involved in the analysis of the T2K experiment data, in the upgrade of the near detector and in the preparation of the next generation experiment, Hyper-Kamiokande. The Neutrinos group is composed of five permanent staff members including four CNRS researchers (J. Dumarchez, C. Giganti, B. Popov, M. Zito) and one lecturer (M. Guigue), four PhD students and two post-docs.
