Abstract
The ETIC consortium will provide the R&D framework to investigate and validate possible configuration
and solutions to be adopted for third generation gravitational-wave detector Einstein Telescope. The
two facilities are dedicated to the implementation needed for cryogenics application for the low-
frequency interferometer (ET-LF) as well as those for the high-frequency interferometer (ET-HF), which
are the concept components of Einstein Telescope detector.The main, in common to the two facilities, is
the development of 1:1 scale payloads, investigating cryogenics versus test mass suspension, low-
mechancial dissipation issues. While cryogenics will be the main objective of ARC facility in at Roma
Sapienza University, the interferometric control of seismic isolated payloads at room temperature will
be the topic of CAOS.
