Commissioning of DC-280 cyclotron complex (JINR TV, July 12, 2018)
FLNR JINR DC-280 cyclotron complex. Commissioning of all systems is under way.
JINR SI Department
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 present rate of superheavy nuclei production by one-two orders of magnitude. This will enable studies of nuclear/atomic structures of heaviest atoms and open the door to the discoveries of the 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;
