Start-up of U400 isochronous cyclotron

FLNR "On the last day of Dec, 1978 at Dubna, a new heavy-ion accelerator was started up - the 4-meter isochronous cyclotron U-400. This unique facility for nuclear-physics research was planned and constructed in three years by a team of scientists, engineers and workers under the direction of Academician G.N. Flerov and Doctor of Physicomathematical Sciences Yu.Ts.Oganessian .

The new accelerator is intended for the production of intense beams of fast ions of almost all elements of the Mendeteev table. The main range of mass numbers of the accelerated particles is 20 ≤ A ≤ 140. Ions of this mass range can be accelerated to an energy of 10 MeV/nucleon or less. The requirement for applied research for an energy of 1-2 MeV/nucleon can be met for all ions with mass number 12 ≤ A ≤ 240. Light particles with A ≤ 20 can be accelerated to an energy of 30-40 MeV/nucleon."
