Description
The ET cryogenic tower will operate at 10–20 K, featuring exceptionally low vacuum level and implementing ultra-low noise technologies. Beyond cryostat development, a number of elements and GW instrumentation remain to be adapted or validated. Here we present an existing cryostat located at Virgo site, known as the ‘1500W’ facility, recently refurbished and operated with cryocoolers providing a combined cooling power up to ~2 W at 4 K. The facility is now open for studies within the ET Collaboration.
