3G R&D: R&D for the Next Generation of Ground-based Gravitational-wave Detectors

Understand

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.
