Synopsis

Neutrino - Introduction Sources of Neutrinos Impacts of Neutrino

research Neutrino detectors India’s role Conclusion

2

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.

3

What is Neutrino ?

Neutral subatomic particle of very low mass.

Belong to the Lepton family. Affected only by weakest of nature’s

force.

4

Sources of Neutrinos5

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.

6

Why Neutrino research is essential

7

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

8

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.

9

Extraterrestrial communications

Neutrinos plays a great role in SETI.

Penetrate massive interstellar clouds.

Detection neutrino carrying information provide evidence of Alien civilizations

10

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.

11

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.

12

Other applications

Detect minerals and oil deposits

Medical imaging Earth quake monitoring

13

Famous Neutrino observatories

Icecube neutrino observatory

Fermilab neutrino detector

CERN neutrino platform

14

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

India based Neutrino Observatory

The INO collaboration has now decided on a site in Bodi West Hills in Thenidistrict.

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.

16

Conclusion17

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”

CONCLUSION

Science has no boundaries,It expands when human thinking

expands
