The India-based Neutrino Observatory (INO) Project is a multi-institutional effort aimed at building a world-class underground laboratory with a rock cover of approximately 1200 meter. The underground laboratory, consisting of a large cavern of size 132m ? 26m ? 20m and several smaller caverns, will be accessed by a 1900 m long and 7.5 m wide tunnel.
