Wireless power transfer for cryogenic sensors and actuators in the Einstein Telescope — •santosh mutum1, christian grewing1, andre zambanini1, and stefan van waasen1,2 — 1Central Institute of Engineering, Electronics and Analytics, Electronic Systems, Forschungszentrum Jülich, Germany — 2Faculty of Engineering, Communication Systems, University of Duisburg-Essen, Germany
Gravitational wave detectors have to be extremely sensitive by nature. Hence, a significant effort is required to investigate in optimizing the hardware setup to reduce noise impacts as much as possible. For the upcoming Einstein Telescope, an optical power and information transfer is proposed and investigated to limit the mechanical coupling of cables. Additionally, in order to achieve more sensitivity in the proposed third generation gravitational wave detector, the main optics and consequently the electronics of the interferometer need to be cooled down to cryogenic temperatures.
This talk will address the wireless power transfer for the sensor-actuator system. The concept of a wireless power transfer in cryogenic using laser and solar cell will be discussed as well as first measurements and estimations for the expected performance.
