Heavy ion acceleration using 224 cm cyclotron at Kolkata

The cyclotron at Kolkata after accelerating light ions for twenty years was shut down in early 1997 for modification of the central region and connecting the 6.4 Ghz ECR source to the cyclotron. After carrying out several modifications and installation of the axial injection line the beam trials were started. The first heavy ion beam was obtained in early ’98. Using oxygen as the test beam most of the initial debugging was done. Now the beams have been made available to the users for experiments. The second ECR ion source has been added to increase the range of energy and ion species.
