LIGO-India: A proposed mega-science project in India’s next 5-year plan

• A project on Indian soil with International Cooperation• Involvement at the threshold of a major science discovery• aLIGO-USA precedes LIGO-India by ~3 years. Staggered time-line is an advantage.

– Indian experimenters would participate in aLIGO-USA – Significant US expertise will pave way for faster execution of LIGO-India

• US hardware contribution ready: no uncertainty in timeline– aLIGO is one of NSF’s most ambitious funded projects– LIGO-India got positive reviews , NSB approval for NSF to proceed as it deems best.

• Expenditure entirely in Indian labs & Industry. • Very significant Industrial capability upgrade. Indian DAE labs &

Industry assessed to be in position to carry out phase-I of LIGO-India. (Senior LIGO team visited Indian labs & facilities in Aug ,Oct, Dec 2011, Feb 2012]

• Well defined training plan Generate large number (~100) of highly trained scientists.

• Major data analysis centre for the entire LIGO network. Huge opportunity for Indian University participation.

Three Phases of LIGO-India project

LIGO-India Project is broadly divided into three phases:

Phase 1 (Sept 2012 – June 2014) – Site selection, infrastructure & facility and vacuum system design and prototyping of beam tube.

Phase 2 (July 2014 – Dec 2017) – Infrastructure & facility preparation, vacuum construction and testing at vendor site, training of Indian Scientists / Engineers, shipping of detector and documentation of the detector hardware components, their installation and testing off-site (RRCAT)

Phase 3 (2018-2020) – Detector installation and commissioning on site

Manpower and Human Resource Development

The construction and subsequent operation of the observatory will require ~ 50 scientists and engineers.

~10 critical manpower for the project team will be seconded from lead centers

The facilities like engineering, drafting etc. from the participating institutes will also be used.

During Project execution phase project scientist / engineers will be hired for duration of five years.

Necessary work / required facilities will be outsourced.

~ 40 new positions will be created.

A committee will be constituted, which will assist in generating manpower.

Requirements / metric:• Low ‘seismicity’ (ground noise PSD)• Low human generated noise• Air connectivity, road connectivity, data connectivity,…• Proximity to academic institutions, labs, industry preferred, …

Approach : • Identify potential sites not too far from existing facilities• Establish contact with local & high level state officials• Desktop survey of sites, followed by team visit• 2-3wk seismic survey: ground noise PSD at 0.1-100 Hz range• Few interesting possibilities have emerged.

To summarize…

• Is there enough scientific interest in the community in India? Yes

• Does the community have sufficient scientific, technical and managerial ability to implement this megaproject? Yes

• Would adequate funding and support be available? Very likely • Can the project be sustained over ~15 years? Yes• Is there a suitable site? Several possibilities


In the past year (2012), pre-approval phase:

Miles covered, inches to go …. toward Indian govt. approval.

Post-approval:

Important challenges ahead, but gearing up well to face them
