    SuperHeavy Element Factory

  • Creation of SHE factory based on the high-intensity universal DC-280 cyclotron (A ≤ 238, E ≤ 10 MeV·A, I ≤ 20 pµA) in a new separate experimental building is a part of the DRIBs-III project according to the Seven-Year Plan for the Development of JINR 2010-2016 approved by the Committee of Plenipotentiaries of the Governments of the JINR Member States (CPP) in November 2009.

  • The SuperHeavy Element Factory will increase the overall production of super-heavy nuclei by two orders of magnitude with respect to presently achieved rates. This will enable the studies of nuclear /atomic structure of heaviest atoms and open the door to the discoveries of new elements above Z=118 and of isotopes closer to the predicted shell closure at N=184.
