AbstractAbstract
[en] The present paper is focused on study of leaks in Indus-2 Vacuum System followed by monitoring the opening of leaks with the help of ion current changes from Sputter Ion Pump (SIP) Controller, vacuum readings from B-A Gauges and leak repairs with the help of Residual Gas Analyzers. The 172.47 meter long Indus-2 Vacuum System is sectored into 10 segments initially (till November, 2014) and 12 segments from January, 2015 with the help of 12 nos. of all metal R.F.Contact Sector Valves. Leak Localization is determined by continuous monitoring the change in pressure readings of Hot Cathode Ionization (B-A) Gauges in addition to the increase in ion currents of Sputter Ion Pumps distributed around the Indus-2 Vacuum segments. A total of more than 25 leaks with varying leak rates of 1x10"-"1"0 to 1x10"-"5 mbarl/s are repaired since Oct, 2006 to till today without much delay and intervention of machine operation schedule.
