3. Pauli’s Hypothesis
 In 1930, Pauli had the
idea of neutrino
 To explain the missing
energy during Beta
decay.
 His idea was later led by
Fermi.

4. What is Neutrino ?
 Neutral subatomic particle of very
low mass.
 Belong to the Lepton family.
 Affected only by weakest of nature’s
force.

5. Sources of Neutrinos

6. First experimental detection
 In 1942, Wang Ganchang first proposed
the use of beta capture to experimentally
detect neutrinos
 Group of scientists detect neutrino by
Cowan–Reines neutrino experiment in
1956.
 Nobel Prize in 1995 given as a reward for
this.

7. Why Neutrino research is essential

8. Faster Global Communications
 Drawback of Electromagnetic
wave is they don’t passes
through all matter.
 Neutrinos easily penetrate
through all matter
 With almost the speed of light
 Communication tool for future

9. First message using Neutrino beam
 On Apr 2012, scientists of
Fermilab send a first message
using neutrino beam
 They convert ‘NEUTRINO’ to
binary code.
 Distance over 1035m with
240m of Earth.
 Successfully received by
MIVERvA detector.

10. Extraterrestrial communications
 Neutrinos plays a great role
in SETI.
 Penetrate massive interstellar
clouds.
 Detection neutrino carrying
information provide evidence
of Alien civilizations

11. To predict Dark matters
 Hypothetical kind of matter would
account for most of the matter in the
Universe.
 Neutrinos could be the missing link of
dark matters.
 Dark matter search from collision of
neutrinos from sun or other
astrophysical sources.

12. To monitor nuclear proliferation
 Antineutrino detector to monitor a nuclear
reactor for the production of weapon.
 No. of antineutrinos produced and their
energy spectrum, indicates nuclear process
 Future tool of nuclear proliferation.

13. Other applications
Detect minerals
and oil deposits
Medical imaging Earth quake
monitoring

14. Famous Neutrino observatories
Icecube neutrino observatory
Fermilab neutrino detector
CERN neutrino platform

15. India’s role
 Indians are pioneers in Neutrino
science at 1960’s
 Kolar gold field laboratory in
Karnataka
 INO established to reclaim our role
in neutrino science
15

16. India based Neutrino Observatory
 The INO collaboration has now decided
on a site in Bodi West Hills in Theni
district.
 The underground laboratory, consisting
of a large cavern of 2100 m long and
7.5 m wide tunnel.
 ICAL is the world’s most massive
magnet, 4 times of CERN.

17. Conclusion
17
 Neutrinos have the secret of the
Universe.
 Neutrino have a power to solve the
unsolved mysteries of Science.
 When we implement the applications
of Neutrino research make our
“Universe- a Hamlet”

18. CONCLUSION
Science has no boundaries,
It expands when human thinking
expands
