Superconducting tunnel junction bolometers

2014 Two new types of superconducting infrared bolometer are described. In one, the temperature dependent Josephson current in an SNS junction is measured with a SQUID galvanometer. In the other, the temperature-dependent quasiparticle tunneling current in an SIN junction is measured with a conventional fet amplifier. Either type of junction is deposited on a low heat capacity sapphire substrat...

Suspended Tunnel Junction Bolometers For Terahertz Range

Implementation of high resolution passive THz cameras operated at cryogenic temperatures of a few Kelvin benefits from a large number of pixels. At present, building a cryogenic multiplexed read-out circuit represents a challenging task. Here we propose and demonstrate broadband niobium-based tunnel junction bolometers operating in equilibrium regime at 4 K, and read out with a room temperature...

Noise mechanisms in superconducting tunnel-junction detectors

We present a theory and measurements of noise mechanisms in superconducting tunnel-junction detectors used as single-photon spectrometers. These mechanisms result from incomplete cooling of the excited quasiparticles in the tunnel-junction electrode. Due to the incomplete cooling, only a fraction of the initially created charge is collected by tunneling. Additional effects include reduced dynam...

Multiple junction biasing of superconducting tunnel junction detectors

We describe a biasing scheme for single-photon detectors based on superconducting tunnel junctions. It replaces a single detector junction with a circuit of three junctions and achieves biasing of a detector junction at subgap currents without the use of an external magnetic field. The biasing occurs through the nonlinear interaction of the three junctions, which we demonstrate through numerica...

Superconducting Tes Bolometers above 1k

The discovery of High Tc superconductivity led to the exploration of current-biased superconducting bolometers cooled with liquid nitrogen and optimized to view 300K backgrounds at wavelengths beyond 10 μm. If such detectors reach the thermal fluctuation noise limit they would be a great improvement over room temperature pyroelectric detectors and thermopiles for many applications. The supercon...
