Abstract: (IOP)
The personal view for the next to the next neutrino detector, the ultimate experiment, is discussed. Considering the size, cost and head winds against the basic science, the ultimate experiment will be the only experiment in the world. Here two su ch experiments one for the neutrino oscillation and the other for the double beta decay were discussed. The ultimate experiment needs to include a bread and butter science and to have a discovery potential for an unexpected phenomenon. There are many tech nical challenges and international co-operations are absolutely necessary.
  • neutrino: oscillation
  • neutrino: detector
  • double-beta decay
