Phase cameras (PCs) - developed at Nikhef and recently installed at Advanced Virgo - are capable of probing wavefront amplitude and phase in 2D for any frequency. This allows for monitoring the frequencies used to generate the error signals to lock the interferometer. Additionally, the PC has been used in the past to inform on wavefront distortions due to thermal defects in the mirrors....

10. A superconducting inertial sensor for low-frequency and cryogenic gravitational wave detectors

We are developing a Cryogenic Superconducting Inertial Sensor (CSIS) to be employed in the forthcoming Einstein Telescope (ET). The designed displacement sensitivity for this device is a few fm/√Hz at 0.5 Hz, which is 3 orders of magnitude more sensitive than the state-of-the-art. The sensor will open pathways to monitor low-vibration motions of cryocoolers applied to the penultimate stage of...

12. Detecting planetary-mass primordial black holes with resonant electromagnetic gravitational-wave detectors

The possibility to detect gravitational waves (GW) from planetary-mass primordial black hole (PBH) binaries with electromagnetic (EM) detectors of high-frequency GWs is investigated. We consider two patented experimental designs, based on the inverse Gertsenshtein effect, in which incoming GWs passing through a static magnetic field induce EM excitations inside either a TM cavity or a TEM...
