The Kiev 240‐CM Isochronous Cyclotron

In Nuclear Research Institute of Ukrainian Academy of Sciences in Kiev the construction of 240‐cm isochronous cyclotron is being accomplished. The accelerator design is developed by D.V.Efremov Scientific Research Institute of Electrophysical Apparatus in Leningrad. The cyclotron is being in the state of assembly and adjustment. The cyclotron provides for variable‐energy protons up to 80 MeV of high beam quality as well as neutron pulses with duration less than two nanosec at pulse rate from 1 kHz to 100 kHz. At joint operation with the designed tandem generator xenon ions can be accelerated up to the energy being higher the Coulomb barrier. In the present paper main data concerning the cyclotron and its main mode operation are described.
