Operation of the Variable Energy Cyclotron at Calcutta

The 224 cm Variable Energy Cyclotron at Calcutta with design energies of 140 Q2/A has been completed. An internal beam of 50 MeV alphas has been obtained in June, 1977. An external beam of 30 MeV alphas has been obtained in July, 1978. During the internal beam trials and the external beam trials, experience has been gained on the operation of various systems and the reliability tested. Results obtained are presented. Beam Transport and Data Processing Systems are being installed and plans for utilization are under way.
