The Dept. Of atomic Energy (DAE) estimates Rs 1,260 crore for the LIGO India project
The estimated funding requirement for ambitious LIGO India
project of setting up interferometer to record gravitational waves in
collaboration with the US-based detectors will see an upward revision - a
figure the department of atomic energy is expected to compute in a month.
The Dept. Of atomic Energy (DAE) is expected to foot a
revised figure of estimate for the project in a month, once it is cleared by
the LIGO India Project Management Board.
It is chaired by director city-based Raja Ramanna Centre for
Advanced Technology (RRCAT).
The union cabinet gave an in-principle nod of Rs 1,260 crore
for the LIGO India project.
It included funds for
site acquisition, building of infrastructure, guiding systems, detector
components and keeping it operational for next 10 years.
The initial estimate was arrived at in 2012.
It took time to hunt for the site - 4km by 4 km land area.
RRCAT scientists are involved in scouting land for the LIGO
India project and developing and operationalizing critical components of the
detector in collaboration with the US-based LIGO Science Collaboration.
The cost of the project will have to be revisited.
A new estimate is expected to be brought before the project
management board for approval in one month.
Once it is approved, DAE is expected to take up the matter
with the government.
The LIGO India project is the advanced gravitational-wave
detector planned in India in collaboration with US-based LIGO (Laser Interferometer
Gravitational-Wave Observatory) Science Collaboration.
The detector in India
will form a triangulate along with the two US-based instruments in recording
gravitational waves with more accuracy.
Earlier, the detector was planned to be established in Australia
- in the southern hemisphere for better triangulation.
But Australia could not garner funds, thus US consortium
offered the same to India.
The LIGO India project is expected to be installed in 2012.
Once the site is finalized, the directorate of constructions
services and estate management will start working on developing the
The detector components, many developed in RRCAT, will be
simultaneously developed with the help of the US.
The actual science operations will start by 2025.
It takes a lot of time to tune the interferometer.
LIGO India Scientific Board is chaired by director of the
Inter-University Centre for Astronomy and Astrophysics, Pune.
Once the project becomes operational, it will work on the
science with the detector - astronomy and astrophysics.
It will also oversee how to liaison with institutes and
other academic works.
A rough estimate suggests that over 500 trained scientists
are required to run the project.
The RRCAT is in the process of training them in
collaboration with the projects.
