Title: The Radioactive Ion Beam & other Major Accelerator Activities in India  

Abstract: An ISOL (Isotope Separator On-line) post-accelerator type of Radioactive Ion Beam (RIB) facility is being developed at Variable Energy Cyclotron Centre, Kolkata, India at present. Light ion beams from the K=130 cyclotron in conjugation with suitable thick targets will produce the RIBs.  A properly optimized target design will ensure that the RIBs will diffuse out of the thick target and enter in to an on-line ion source.  The RIB of interest will be separated from other reaction products using an ISOL system.  The RIB at this stage has an energy of 1 keV/u, which will be accelerated in steps.  The first stage of acceleration will utilize a heavy ion RFQ (Radio Frequency Quadrupole) to accelerate up to 86 keV/u. The next stage of post-acceleration will provide around 400 keV/u using three LINAC cavities.

Apart from this highly challenging activity of RI beam development, many other interesting accelerator projects are going on in India.  The speaker intends to give a flavour of these accelerator development acitivities, the success stories so far and the things to come in the near future in his presentation.
