Instrumentation
Time Projection Chambers (TPC) installation completed at J-PARC
September 13, 2023
Neutrinos GroupThe detector is already connected to the gas system and first cosmics in this configuration are expected to be recorded in about 4 weeks. First data taking with a neutrino beam is planned for the 2nd half of November and December.
The first of two Time Projection Chambers (TPC) was delivered to J-PARC end of August. After undergoing a serious of quality checks after the transport from CERN to J-PARC, on the 7th of September, the detector was transported to the final building and installation in the experiment was then successfully carried out.

Milestone
Cavern Excavation Completed for Hyper-Kamiokande
September 1, 2025
The completion of the underground cavern for Hyper-Kamiokande in Japan marks a key research milestone in the construction of a next-generation neutrino observatory. The Institut de Física d’Altes Energies (IFAE) participates in the project through its Neutrino group, contributing to detector development and the scientific programme of this major international research infrastructure.
