Single SQUID Multiplexer for Arrays of Voltage-biased Superconducting Bolometers
We describe a frequency domain superconducting quantum interference device (SQUID) multiplexer which monitors a row of low-temperature sensors simultaneously with a single SQUID. Each sensor is ac biased with a unique frequency and all the sensor currents are added in a superconducting summing loop. A single SQUID measures the current in the summing loop, and the individual signals are lock-in ...
متن کاملDesign and characterization of TES bolometers and SQUID readout electronics for a balloon-borne application
We present measurements of the electrical and thermal properties of new arrays of bolometeric detectors that were fabricated as part of a program to develop bolometers optimized for the low photon background of the EBEX balloon-borne experiment. An array consists of 140 spider-web transition edge sensor bolometers microfabricated on a 4” diameter silicon wafer. The designed average thermal cond...
متن کاملSuspended 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...
متن کاملAntenna-coupled TES Arrays For The BICEP2/Keck and SPIDER polarimeters
The upcoming Cosmic Microwave Background (CMB) experiments BICEP2/Keck and SPIDER will be using planar arrays of polarization sensitive antenna-coupled TES bolometers, operating at frequencies between 96GEIZ and 220 GEIz. At 145 GlTz each array consists of 64 polarimeters (128 TES sensors) and four of these arrays are assembled together to make a focal plane. The detector arrays are integrated ...
متن کاملDynamic Harmonic Analysis of Long Term over Voltages Based on Time Varying Fourier series in Extended Harmonic Domain
Harmonics have become an important issue in modern power systems. The widespread penetration of non-linear loads to emerging power systems has turned power quality analysis into an important operation issue under both steady state and transient conditions. This paper employs an Extended Harmonic Domain (EHD) based framework for dynamic analysis of long term analysis over voltages during the tra...
