| Outline of Final Research Achievements |
The Super-Kamiokande (SK) detector is one of the most sensitive detector to observe supernova burst neutrinos. Recently, there are discussions of possibility that some stars, which are around 500 light years from the Earth, may became supernova. If this happens, more than 60 million neutrinos are expected to interact in SK. With the current data acquisition ( DAQ ) system, we can record ~ 20% of the data just after the burst. Therefore, we developed a new module to record necessary information without any loss even if nearby supernova occurs. At the same time, we have improved the software for the existing DAQ system to record entire data from the detector for 1 minutes before and after the neutrino burst. This data will make it possible to analyze small activity just before the supernova burst occurred. These additional data are expected to provide important information to understand the detail mechanism of supernova bursts.
