Description
ETpathfinder is a R&D fieldlab aiming to provide a testbed for research, development, integration and validation of ET-LF technologies in an environment similar to ET. In particular the interferometer configuration featuring four cryogenic towers and two flexible bench towers (for input and output optics) allows for the construction of full Fabry-Perot Michelson interferometer, with a displacement sensitivity of 1e-18m/sqrt(Hz). This talk will give an status update of the ETpathfinder project and detail some of the recent achievements, not only from the academic partners within the ETpathfinder collaboration, but also highlighting several contributions from industry partners. We conclude by giving an outlook of potential future developments.
