文摘

We describe a new fabrication process for a superconducting, flexible, and demountable connector to a kilo-pixel transition edge sensor. The demountable part contains planar coils for inductive coupling, in particular suited for AC-biased frequency domain multiplexed readout. A fixed connection to a chip with superconducting LC filters and SQUID readout is made by gold bump bonding with a connection resistance of \(1.1\,{\times }\,10^{-4}\, \Omega \). The Nb-based connecting lines on the flexible part show a superconducting transition around 7 K, which enables testing of connectors and LC filters in a simple L-He setup.KeywordsTransition edge sensorsFrequency division multiplexingFlexible interconnect
