VEC, Calcutta: Developments and status

VEC is now operating regularly for experiments with alpha beams with energies between 26 to 85 MeV. This national facility is being utilized by various user groups for basic and applied research in nuclear physics, solid state physics, radiochemistry, biomedicine and radioisotope production. A new driven radiofrequency system based on the RCA 4648 tube has been incorporated. The performance of the beam transport system has been greatly improved. Narrow pulses of 4 ns (100 RF) width could be obtained without the use of internal slits. High resolution beam lines are being designed. Fabrication and development work on a QSD magnetic spectro-meter is progressing rapidly. A powerful new data acquisition system has been installed to meet the nuclear physics users' requirements. First design of an external injection system for an ECR source has been developed
