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 one-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.
SHE Factory Goals
Experiments at the extremely low (σ<100 fb) cross sections:
- Synthesis of new SHE in reactions with 50Ti, 54Cr …;
- Synthesis of new isotopes of SHE;
- Study of decay properties of SHE;
- Study of excitation functions.
Experiments requiring high statistics:
- Nuclear spectroscopy of SHE;
- Precise mass measurements;
- Study of chemical properties of SHE.
- DC280 cyclotron, a stand-alone SHE-factory
- Synthesis and study of properties of superheavy elements;
- Search for new reactions for SHE-synthesis;
- Chemistry of new elements;
