Time-division multiplexing (TDM) of transition-edge-sensor (TES) microcalorimeters is being developed as the readout tech-nology for the Athena X-ray integral

Indium Bump Process for Low-Temperature Detectors and Readout

Author(s)
Tammy Lucas, John Biesecker, W.Bertrand (Randy) Doriese, Shannon Duff, Gene C. Hilton, Joel Ullom, Michael Vissers, Dan Schmidt
We describe our indium bump process for low-temperature detectors and associated readout. A titanium nitride under bump metallization layer (UBM) is reactively

Cryogenic Thermometer Based On A Two-Level System (TLS)

NIST Inventors
Michael Vissers , Jordan Wheeler and Maxime Malnou
We have invented a new type of cryogenic thermometer for use at temperature below 1 Kelvin. The device consists of a superconducting resonator with dielectric two-level systems (TLS) material deposited or naturally formed on the surface. The temperature is read out by measuring the resonance
