ELiTES Work Packages

E-mail Print PDF

The ELiTES project is organized in four Work Packages:

  • WP1, "Cryogenics and suspensions", chaired by Ettore Majorana (Roma University/INFN), having the following objectives:
    • Measure of the performance of designed cryogenic suspension system in a practical interferometer from the point of seismic and vibration isolation
    • Design and test of auxiliary attenuation system for thermal link
  • WP2, "Mirror thermal noise and cryogenics", chaired by Ronny Nawrodt (FSU), having the following objectives:
    • Investigation of the mechanical loss in both silicon and sapphire bulk materials;
    • Performance of suitable optical coatings on sapphire substrates for the development of the mirrors for LCGT and to share the complimentary expertise contained within the LCGT and ET groups (e.g. Japanese expertise in studying low temperature properties of sapphire, European expertise in studying low temperature coatings)
    • Assessment of the properties and suitability of silicate bonding for bonding sapphire, and comparison with the properties of bonded silicon, to develop techniques for constructing sapphire suspensions for use in LCGT and as a possible alternate suspension material for use in ET
    • Characterisation of the thermal and mechanical properties of suspension elements (fibres, bond areas, etc.)
  • WP3, "Large-scale cryogenic infrastructure for LCGT and ET", chaired by Kentaro Somiya (ICRR), having the following objectives:
    • Specifying noise sources arising from cooling system quantatively and qualitatively
    • Optimum design of raditation shield
    • Prevention of possbile contamination of clean surface of mirrors
  • WP4, "Management", chaired by Michele Punturo (EGO and INFN, Project coordinator), 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.
