Ring Cyclotron

Ring Cyclotron

The beams extracted from the AVF cyclotron are transported through one of the beam lines of the nuclear physics facility and injected into the Ring Cyclotron. With this accelerator system, beams of protons, deuterons, Helium-3s, alpha particles and light-heavy ions are available in the wide range of energies of up to 400, 200, 510, 400 and 400xQ**2/A MeV, respectively. An emphasis is placed on the production of high quality beams to enable precise experiments.

In the Ring Cyclotron ions are accelerated by three single-gap cavities located at the valley spaces between the spiral sector magnets. To get high quality beams an additional single-gap cavity is introduced for flat-topping purposes. For the preparation of ideal injection beams for the Ring Cyclotron, some apparatus for the detailed treatments of the beams are also considered in the injection line.
