In this work we present the progress on the realization of a superconducting microbolometer sensible to the THz radiation. The operation of this detector is based on an integrated antenna coupled to a suspended strip of superconducting material. The bolometer works anywhere in the temperature range 2-7 K which can be easily reached in helium bath cryostats or closed-cycle cryocoolers. We also report on two possible applications we are working on, one related to a system for homeland security and the other one to astrophysical observations.

Abstract
In this work we present the progress on the realization of a superconducting microbolometer sensible to the THz radiation. The operation of this detector is based on an integrated antenna coupled to a suspended strip of superconducting material. The bolometer works anywhere in the temperature range 2-7 K which can be easily reached in helium bath cryostats or closed-cycle cryocoolers. We also report on two possible applications we are working on, one related to a system for homeland security and the other one to astrophysical observations.File in questo prodotto:
