SC Cyclotron and RIB Facilities in Kolkata

Two advanced accelerator facilities are under construction at this centre, essentially, for basic nuclear physics experiments. Construction of the Kbend=520 superconducting cyclotron for accelerating heavy ion beams is nearing completion. The main magnet was recently enrgized in the cyclotron vault. The excitation current is gradually being raised to reach the design value. Most of the major components/systems are being fabricated at various locations. We plan to start assembly of the cyclotron in the last quarter of 2005. Experimental facilities are also under design and construction by the user groups. The Radioactive Ion Beam (RIB) facility will use the existing K=130 room temperature cyclotron as the primary beam source and will be housed in a large experimental area. The major components of this facility consist of a target system, on-line ECRIS “charge breeder”, a low beta RFQ and an IH linac. Several components of this complex facility have been developed or fabricated. The developemnt work on the others is going on. The design energy at the end of three linac tanks is about 400 keV/nucleon, to be achieved around the end of 2006.
