Webb21 juli 2024 · Statistical distributions of the analog readings of an antenna-coupled THz superconducting bolometer were measured and analyzed under a special type of irradiation by low-energy fluxes of THz photons with Poisson photon statistics and controllable mean photon numbers. WebbFinally, detection of the THz signals by space telescopes implies high resistance of the bolometer to ionizing radiation. Concluding, only materials that combine (i) high absorption ability, (ii) frequency tunability and (iii) radiation hardness can offer efficient platform for ultrafast and ultrasensitive THz bolometer for space applications.
