Thermal KIDs
The project aims to develop superconducting microwave microresonators (MKIDs) applied to neutrino physics has brought our focus to pursue the development of these very promising detectors used in the quasi-thermal equilibrium mode.
The sensors that we are aiming for with this R&D work would benefit from the excellent energy resolution achievable with equilibrium detectors combined with the microwave multiplexing which comes natural with MKIDs.
These devices can be of use in a very wide variety of applications, since they are potentially able to achieve high energy resolution over a broad energy range (1-100 keV). Kilo-pixel arrays of such devices may have a large impact in many frontier fields like astrophysics, material analysis, nuclear safety and diagnostic, archaeometry, ...
In the context of this work, we are optimizing the design and developing new materials to produce the detectors. This is done in collaboration with the Micro-ElectroMechanical Systems at Fondazione Bruno Kessler (Povo, Trento, Italy) and the QN Metrologia quantistica e nanotecnologie at Istituto Nazionale di Ricerca Metrologica. In addition to the study of superconducting films of Ti/TiN multilayer, we also plan to test devices made of multilayers of Ti/Al.
