Atmospheric neutrino detector
at Kolar Gold Field –1965
A large mass detector with charge identification capability
= P(nm nm; L/E)
The disappearance probability can be measured with a single detector and two equal sources:
= 1 - sin2 (2Q) sin2 (1.27 Dm2 L/E)

Neutrino Event Generation
νa+ X -> A + B + ...
Generates particles that result from a random interaction of a neutrino with matter using theoretical models .
i) Reaction Channel
ii) Vertex Information
Iii) Energy & Momentum of all Particles
i) x,y,z,t of the particles at their interaction point in detector
ii) Energy deposited
iii) Momentum information
A + B + ... through RPCs + Mag.Field
Simulate propagation of particles through the detector (RPCs + Magnetic Field)
i) Digitised output of the previous stage (simulation)
(x,y,z,t) of A + B + ... + noise + detector efficiency
Add detector efficiency and noise to the hits
i) Energy & Momentum of the
(E,p) of ν + X = (E,p) of A + B + ...
Fit the tracks of A + B + ... to get their energy and

INO Training School:
We have already started INO graduate training program from August 2008.
Affiliated to HBNI.
At present INO students are being trained for one year at TIFR, Mumbai in both experimental techniques and theory.
Being attached to Ph.D. guides at various collaborating institutions for a Ph. D. degree after completion of coursework
