Abstract:
To deliver on the promise of next generation gravitational-wave
observatories, a sustained and coordinated detector research and development
program is required. This report examines in detail the wide range of nearer-
and longer-term detector R&D programs needed for next generation GW detectors
commensurate with the key science targets presented in "The Next Generation
Global Gravitational Wave Observatory: The Science Book", including
considerations of site selection and large-scale vacuum infrastructure. The
report makes a series of detailed recommendations on the needed advances in
detector technology and the timescales needed to achieve those advances. It
also identifies areas where larger-scale globally coordinated R&D efforts will
be critical to ensuring success while minimizing costs.
This report is the third in a six part series of reports by the GWIC 3G
Subcommittee: i) Expanding the Reach of Gravitational Wave Observatories to the
Edge of the Universe, ii) The Next Generation Global Gravitational Wave
Observatory: The Science Book, iii) 3G R&D: R&D for the Next Generation of
Ground-based Gravitational Wave Detectors (this report), iv) Gravitational Wave
Data Analysis: Computing Challenges in the 3G Era, v) Future Ground-based
Gravitational-wave Observatories: Synergies with Other Scientific Communities,
and vi) An Exploration of Possible Governance Models for the Future Global
Gravitational-Wave Observatory Network.
