At Rome University “La Sapienza” we are building a new Lab dedicated to developing real size cryogenic payloads for ET. The Lab is being financed by the Amaldi Research Center and should be completed at the beginning of next year. In the meantime we are preparing a prototype pulse tube cooling station and we have started to design the test cryostat for the ET-LF Payload prototype.
With the discovery and direct measurement of gravitational waves from merging binary black holes and binary neutron stars by the Advanced LIGO and Advanced Virgo detectors a new era of gravitational wave astronomy has begun. Since the current detectors are moving closer to reaching their infrastructural limits, the drive for a third-generation gravitational wave detector increases. The...
The Sar-Grav Laboratory is a seed of the third generation of gravitational wave interferometer: Einstein Telescope. The infrastructure is located beside the Sos Enattos mine in Lula (Nuoro, Sardinia). The region is characterized by a very low seismic and anthropogenic noise therefore, Sar-Grav aims to host underground experiments like low seismic noise experiments, cryogenic payloads, low...
The LIGO Voyager upgrade is designed to maximize the reach of the existing observatory facilities, with radiatively-cooled silicon optics and coatings that enable high-power cryogenic interferometry. I will discuss the ongoing project to realize this design at the 40 m Lab.
Using the optical coating facility at the ANU we will concentrate towards low-loss optical coatings for large scale optics used in gravitational wave detectors. The work is focused on the near-term needs and long-term requirements, either for 1 um or 2 um optical wavelengths. Also work on 2 um optical squeezing generation and its control is underway. A low-frequency gravitational-force sensor...
In this talk we present the plans in Glasgow to upgrade or 10m interferometer into a cryogenic facility. The facility will utilise a single 10m reference cavity based on suspended fused silica optics, and a pair of Leidon cryocoolers for a short cryogenic reference cavity. The facility is aimed to be a fast turnaround system with studies focussing on ice growth on optics, monitoring cryogenic...
