  3. LIGO-India: … Site requirement

  4. LIGO-India: … the challenges Indian Site • Primary Requirements: • Flat terrain (minimal earthmoving expense) • Low seismicity (strong events but also continuum background) • Low human generated noise • Air connectivity • Proximity to Academic institutions, labs, industry preferred, … • Identify potential sites not too far from existing facilities • Basic topograph maps, weather data, … • Need to carry out seismic survey to get ground noise spectral density at 0.1-10 Hz range • Few interesting possibilities are under investigation • Challakeresite seems to be positive at preliminary assessment

  5. Option • Acquire modest extra adjoining land

  6. Option • Minor Swap with DRDO • Swap with Sheep farm • Minor extra land acquisition

  7. Option • Skirt DRDO • Swap with Sheep farm • minor land acquisition

  8. Preliminary Site Survey Seismic background at Site X

  9. Site characterization: Archived Weather Data at Site X

  10. LIGO-India Site: Usage restrictions in Adjoining region • Current + during >15 year Operations • NO sustained heavy equipment, mining, blasting activity in the vicinity (30km) • NO Reciprocating power-plant machinery, rock crushers and heavy machinery (> 16 km, prefer 40km from the site) • Non-reciprocating power-plant machinery and balanced industrial machinery should be located at least 7km from the site, preferred distance of 16 km. • Railway: >10 kms (preferably 16km) away from any busy railway track active at present, or, possible in the next 15 year. • Roadways: More that 4-6 km from any major busy motor highway. • Airways: More than 60km from any major airport. More that 20km from a not so busy (less than 5 flights/day) airport. • No major water flows during most of the year near the site • (The site should be 100 km to 200 km away from the sea-coast!)

  11. Site for LIGO-India: … current snapshot • IUCAA as the lead institute advanced some funds to carry out site search. Create the basic management structure. • activate contacts: e.g., new institutes, Univ. campuses etc. • Approach GSI for site survey as on contract… may involve other more state specific agencies, private agencies. • A senior GSI (recently retd. Dep DG) as a consultant on designing the campaign (Can be scaled up once LIGO-India project is approved ) • Specific cases: • Challakere site most advanced: contacts at highest level of State admin, short seismic survey, site visit , 2 years of weather data. • Gauribidnur area : Early Gravity test, seismic data known • North Karnataka alternative – Bidar, Gulbarga,… [KST exploring….] • Andhra site (?) : awaiting …. • Rajasthan: few sites near Udaipur, Kishanganj near Jaipur (visit in coming weeks), IIT Jodhpur,… • Chhattisgarh: south of Raipur (/), mid Feb discussions,.. • National level DST-DAE Consortium Flagship Mega-project status is expected to facilitate a systematic site search campaign over many Indian states Thank you !!!
