| Popis: | This research continues to focus on the idea using cyclotronic antineutrino source for purposes of neutrino physics. Long baseline experiments suffer from degeneracies and correlations between $\Theta_{23}$, $\delta_{\rm CP}$ and the mass hierarchy (MH). However the combination of a superconductive cyclotron and a big liquid scintillator detector like JUNO in a medium baseline experiment, which does not depend on the MH, may allow us to determine whether the position of the mixing angle $\Theta_{23}$ is in the lower octant (LO) or upper octant (UO). Such an experiment would improve the precision of the $\Theta_{23}$ measurement to a degree which depends on the CP-phase. Comment: 3 figures |
