The ET R&D project is organized in five Work Packages:

  • WP1, "ET’s scientific potential", chaired by Sathyaprakash (Cardiff University/UK), having the following objectives:
    • Carry out a series of mock ET data and science challenges of increasing complexity
    • Explore how well astrophysical models of GW sources could be tested with ET
    • Investigate possible strong field tests of GR with ET
    • Probe ET’s potential for understanding the geometry and dynamics of the Universe
  • WP2, "Long term seismic and GGN studies of selected sites", chaired by Nikhef (Netherlands), having the following objectives:
    • Studies at candidate sites
    • Sensor and network development
    • Modeling of seismic and GGN noise
  • WP3, "Optical properties of silicon at cryogenic temperatures", chaired by Ronny Nawrodt (Friedrich Schiller Universität Jena, Germany), having the following objectives:
    • Stress induced birefringence of silicon-based optic
    • Homogeneity of optical properties within larger samples
    • Homogeneity of optical properties within larger samples
    • Investigation of Whispering Gallery Mode Oscillators made of silicon to probe absorption and scattering
  • WP4, "ET Control systems", chaired by Andreas Freise (Birmingham University, UK)),having the following objectives:
    • Mitigation scheme for radiation pressure effects for the ET-HF interferometer.
    • Control scheme for the injection of frequency dependent squeezed light.
    • Low-frequency control scheme for the ET-LF interferometer.
    • Mitigation scheme for correlated noise in co-located interferometers.
    • Contamination of potential null stream signals by technical noises.
  • WP4, "Management", chaired by Harald Lück (Leibniz Universität Hannover, Germany), addressed to the overall management of the project

The 8th ET Symposium will be hosted by the Institute of Gravitational Wave Astronomy at the University of Birmingham from 27th to 28th of March, 2017.
The first day of the meeting will be focused on the crucial tchnologies for 3G observatories, the morning of the 28th of March will focus on the science motivation for 3G and finally in the 28th afternoon we will discuss about the 3G and ET future, organisation and strategy.
Registration opens on the 22nd of February 2017. Here it is the link to the event.
