  • Abstract
    We report on the performance of a Nb voltage-biased superconducting bolometer cooled by a closed cycle pulse tube cooler. The VSB has a Tc ~ 8.1 K and an operating impedance of R ~ 800 Ω. A preliminary value for the system optical noise equivalent power (NEP) = 1.8 × 10-12 WHz-1/2 and τ = 0.6 ms.
