WP1.B Cryogenic systems for the LGWA pathfinder
The Lunar Gravitational-wave Antenna (LGWA) was recently proposed to measure surface vibrations induced by passing gravitational waves from astrophysical and cosmological sources.
Inertial sensors are under development with sub-picometer to femtometer precision in the decihertz band. It requires an emulator of the seismic and thermal environment to test and operate these sensors on Earth as part of a TRL6 requirement.
Building on a research facility at INFN-LNGS for the development of a seismic isolation system, we propose to augment the facility by a cryogenic system to emulate the <40K ambient temperature of a lunar permanently shadowed region. Furthermore, we propose to carry out a preliminary engineering study of LGWA and its pathfinder mission “LGWA Soundcheck”.

| Cryogenic system production | The first phase of the activities has started with the definition of requirements, design and optimization of the cryogenic system. The forthcoming phase will be devoted to the executive project of the cryostat. In the final phase the cryostat will be produced through external tenders and inhouse activities. |
