The accelerating structure for the superconducting linac booster for the 15 UD Pelletron at IUAC is a Niobium Quarter Wave Resonator, designed and fabricated as a joint collaboration between IUAC and ANL, USA. Initial resonators required for the first linac module were fabricated at ANL. For fabrication of resonators required for future modules a Superconducting Resonator Fabrication Facility has been set up at IUAC. Three quarter wave resonator (QWR) have been fabricated and fifteen more resonators for the second and third linac modules are in advanced stage of completion.
A project for indigenous fabrication of resonators (IFR) has been started. All the required facilities eg. Electron Beam Welding Machine, Surface Preparation Laboratory and High Vacuum Furnace has been operational.
Booster accelerator will consists of three linac modules, a superbuncher, and a rebuncher. Each module will house eight resonators and a superconducting 8 Tesla solenoid magnet. Three modules put together will provide ion beams upto mass 80 above Coulomb barrier.
