Accelerator Driven Systems (ADS) have evoked lot of interest the world over because of their capability to incinerate the MA (minor actinides) and LLFP (long-lived fission products) radiotoxic waste and utilization of Thorium as an alternative nuclear fuel. One of the main sub-systems of the ADS is a high energy and high current CW proton Accelerator. The accelerator for ADS should have high efficiency and reliability and very low beam losses to allow hands-on maintenance. With this criteria, the physics studies has been done for a 1 GeV, 30 mA proton Linac, using NC structures upto 100 MeV followed by Superconducting elliptical cavities, which accelerate the beam from 100 MeV to 1 GeV. We are also studying the configuration where superconducing spoke resonators are used to accelerate the proton beam from 3-200 MeV followed by elliptical cavities for 200 MeV to 1 GeV .
