  The FLNR's key directions of research: synthesis and study of properties of superheavy elements; properties and structure of light exotic nuclei, reactions with exotic nuclei. radiation effects and physical groundwork of nanotechnology. The scientific program of the JINR FLNR is implemented at U-400, U-400M and IC-100 cyclotrons. Accelerated ions are from Li to Bi with energies of 1-55 MeV/n. The annual operation time is about 15000 hours. To improve the efficiency of experiments on the synthesis of new elements the DC-280 cyclotron has been developed with the following parameters: ion energy - 4-8 MeV/n, masses of accelerated ions - 10-238, beam intensity (up to A=50) - 10 pmkA. The cyclotron is in the stage of assembling. After DC-280 commissioning, the reconstruction of the U-400 and U-400M cyclotrons will be performed. Parameters of the accelerators and the time schedule of reconstruction will be presented.

  The production of metal ion beams by electron cyclotron resonance (ECR) ion sources using the MIVOC (Metal Ions from Volatile Compounds) method is described. The method is based on the use of metal compounds which have high vapor pressure at room temperature, e.g., C2B10H12, Fe(C5H5)2, etc. Intense ion beams of B and Fe were produced using this method at the FLNR JINR cyclotrons. Experiments on the production of cobalt, chromium, vanadium, germanium, and hafnium ion beams were performed at the test bench of ECR ion sources. Main efforts were put into production and acceleration of 50Ti ion beams at the U-400 cyclotron. The experiments on the production of Ti ion beams were performed at the test bench using natural and enriched compounds of titanium (CH3)5C5Ti(CH3)3. All these efforts allowed the production of accelerated titanium and chromium ion beams at the U-400 cyclotron.
