Studying neutrino properties is one of the hottest points in modern particle physics. A few years ago, CERN decided to concentrate on the LHC and to stop the accelerator neutrino programme. However, some new experiments were proposed recently at CERN aimed to study neutrinos in the regions where their properties are poorly known or unexplored.

The international Borexino Collaboration has announced the first observation of neutrinos from the CNO process in the Sun, which experimentally confirms the second mechanism for energy generation in stars. Earlier, only neutrinos from the proton–proton cycle were observed. This discovery is highly important for astrophysics since in stars more massive than the Sun energy is mainly produced through the CNO cycle. The results of the investigation are published in Nature.

The SC230 superconducting cyclotron was designed for the JINR medical research programme implementation. The accelerator is able to provide an intense beam for a new and promising flash therapy method.
The SC230 is an isochronous four-sector compact cyclotron with a 1.7-T magnetic field in the center. Superconducting coils will be enclosed in a cryostat, all other parts of the cyclotron are “warm”. Acceleration is performed at the fourth harmonic mode of the accelerating radio-frequency (RF) system consisting of four resonators located in cyclotron valleys. The accelerator will use an internal Penning-type source with a hot cathode, and the low magnetic field makes it possible to use the external axial beam injection. The results of computer simulation of cyclotron systems are presented.
