Talks about the India Neutrino Observatory that has been hanging fire for sometime now due to environmental issues.
A rock of at least a kilometre thickness is needed to filter all other cosmic-ray-produced particles to enable the detector to detect the elusive neutrinos. Hence we have to go inside a mountain. The Nilgiri mountains were chosen as the suitable site for the underground laboratory because of the stability and safety of the Nilgiri rock. A huge cavern of size 120m x 25m x 30m will be dug under the Nilgiri mountains at 1.3 km below the peak and this will be accessed through a horizontal tunnel of more than 2 km in length. A gigantic magnetised detector weighing 50,000 tonnes will be constructed inside this cavern and will be used to detect and study the neutrinos.
In addition to making major discoveries, the INO will benefit generations of students and young scientists and engineers by training them through participation in a major scientific experiment. Student recruitment and training for the INO has started. The project will also include an INO Centre devoted to R&D in detector technology, which will have far-reaching applications in diverse fields. In spite of progress on all other fronts, the project has been bogged down because of the delay in procuring the required government clearances.
