India-based Neutrino Observatory Proposal

The status of INO 2

Goal : To build an underground laboratory for science with neutrino

physics as the major activity

The detector: Magnetized Iron CALorimeter detector (ICAL) for

detecting atmospheric neutrinos

Detector choice based on Technological capabilities available in the country

Complementarity to planned/existing neutrino detectors in the world

Modularity and possibility of phasing

Compactness and ease of construction

Other Possibilities

Neutrinoless double beta decay, Dark Matter ………
