@conference{10902/36405, year = {2024}, month = {8}, url = {https://hdl.handle.net/10902/36405}, abstract = {This work deals with the development of superconducting Kinetic Inductance Detectors (KIDs) for highly sensitive radio astronomy receivers within W-band (75 to 110 GHz). A bilayer based on superconducting titanium/aluminum (Ti/Al) thin films has been used for assessing its absorption performance in this frequency band at millikelvin temperature. A lumped-element inductor based on a 4th order Hilbert structure is designed to absorb the incoming radiation in two orthogonal linear polarizations. The development of a large-format camera prototype is presented. On one hand, ambient temperature quasi-optical characterization demonstrates a suitable absorption for both polarizations within the W-band. On the other hand, dark cryogenic characterization confirms the successful operation of the multiplexed KID devices providing high-quality factors and an operation yield of 97%. These results confirm these developments to be used in future polarimeter receivers.}, organization = {This work is funded by the following grants: 2023/TCN/005 (Universidad de Cantabria) by Consejería de Industria, Empleo, Innovación y Comercio, Gobierno de Cantabria, Spain; PID2022-137779OB-C43 (Universidad de Cantabria), PID2022-137779OB-C41 (CAB) and PID2022-137779OB-C42 (IMDEA-Nanociencia) by MCIN/AEI/10.13039/501100011033, “ERDF A way of making Europe”, EU “NextGenerationEU”/PRTR; RED2022-134839-T (all groups) by MCIN/AEI/10.13039/501100011033.
