  Inter University Accelerator Centre has been involved in the development of heavy ion accelerators, ion sources, beam lines and experimental facilities for providing various heavy ion beams in a wide energy range varying from a few tens of keV to hundreds of MeV for experiments by more than four hundred research groups from all over India and abroad. A large vertical Pelletron electrostatic tandem accelerator capable of achieving terminal voltage up to 16MV has been in operational for more than a couple of decades. Superconducting niobium linac booster accelerating modules having eight niobium quarter wave resonators each have been developed and used. A high temperature superconducting electron cyclotron resonance ion source (HTS-ECRIS) was designed, fabricated and installed. It is in regular operation for production of highly charged ion beams for alternate high current injector (HCI) system consisting of radio frequency quadrupole and drift tube Linacs. Details of developments of various heavy ion beam facilities and experimental systems at IUAC will be presented.

  The major part of the superconducting linac at IUAC has been operational for the past few years and the last accelerating module is in the final stage of completion. The full linac system consists of five cryostats, housing a total of twenty seven niobium quarter wave resonators. At present, the Superbuncher, the first two linac accelerating modules and the Rebuncher are operational and ion beams in the mass range 12C to 107Ag from Pelletron accelerator have been further accelerated and delivered to conduct experiments. A method of random phase focusing to select the accelerating phase of the resonators between 70° and 110° has been successfully tried to reduce the final time width of the beam bunch. Presently, to improve the accelerating fields of the linac resonators in phase locked condition, efforts are dedicated towards improvement of the cooling efficiency of the drive coupler, enhancement of the microphonics damping efficiency with mixtures of SS-balls and testing of an alternate tuning mechanism based by Piezo Crystal. The beam acceleration through the complete linac is to be performed by end of the summer of 2012.
