Abstract

The 14 UD Pelletron Accelerator at TIFR, Mumbai is operational since its inception in 1988. It was decided to impart enough time for High voltage conditioning to achieve higher operational voltage. Prior to this, comprehensive works such as replacing all the sputter ion Pumps and Titanium sublimation pumps across the Accelerator tube with new or refurbished ones and replacement of Alumina balls in the SF₆ drier with fresh balls were carried out. High voltage conditioning of each module was done. Further conditioning of two modules at a time in overlapping mode improved the terminal voltage. As a result of this rigorous conditioning Terminal voltage of 12.6 MV was achieved and beam has been delivered to users at 12MV terminal. Details of this effort will be presented in this paper.
