Narrow Results

Initiatives by the Indian Initiative in Gravitational Wave Observations (IndIGO) Consortium during the past three years have materialized into concrete plans and project opportunities for instrumentation and research based on advanced interferometer detectors. With the LIGO-India opportunity, this initiative has taken a promising path towards significant participation in gravitational wave (GW) astronomy and research and in developing and nurturing precision fabrication and measurement technologies in India. The proposed LIGO-India detector will foster integrated development of frontier GW research in India and will provide opportunity for substantial contributions to global GW research and astronomy. Widespread interest and enthusiasm about these developments in premier research and educational institutions in India leads to the expectation that there will be a grand surge of activity in precision metrology, instrumentation, data handling and computation etc. in the context of LIGO-India. We will discuss the scope of such research in the backdrop of the current status of the IndIGO action plan and the LIGO-India project.

Advanced LIGO will feature a quadruple suspension with a lower monolithic stage of fused silica in order to meet the seismic and thermal noise requirements. Fused silica ears are silicate bonded onto the polished flats of the test/penultimate mass and fused silica fibres, which are fabricated with a computer controlled CO₂ laser pulling machine, are then laser welded onto the ears. The whole process is robust and has been successfully demonstrated with eight test suspensions to date (six in Glasgow and two at LIGO MIT). In the second quarter of 2010 a monolithic quadruple suspension will be installed into the LIGO Advanced Systems Test Interferometer (LASTI) at MIT, Boston.
