Description
Neutrino observations from nearby supernova (SN) bursts play a key role in understanding the SN explosion mechanism. However, the neutrino-oxygen interaction in a few tens MeV, which is important for the observation in Super-Kamiokande, is not well measured, and the neutrino information cannot fully be obtained from the precious SN burst. Therefore, a detailed understanding of this reaction is essential to maximizing supernova neutrino observations.
Therefore, a new neutrino cross-section measurement is proposed using the Spallation Neutrino Source (SNS) in Oak Ridge National Laboratory (ORNL). The preparation of this experiment is ongoing with the support of the US-Japan Science and Technology
Cooperation Program in High Energy Physics for JFY2024 and a newly approved Grant-in-Aid.
This poster reports the current situation results of a prototype test in Kamioka, Japan, and prospect to the plan of ORNL measurement.
