- Title
Feasibility of a Frequency-Multiplexed TES Read-Out Using Superconducting Tunnel Junctions.

- Abstract
We describe a feasibility study of a frequency multiplexed read-out scheme for large number transition edge sensor arrays. The read-out makes use of frequency up- and down-conversion and RF-to-DC conversion with superconducting-isolator-superconducting tunnel junctions operating at GHz frequencies, in combination with an existing frequency multiplexed read-out at MHz frequencies. The read-out scheme can drastically reduce the wiring from room temperature to the cryogenic detectors, with a possibility to read-out and control as many as 30000 pixels over three coaxial lines within a bandwidth of 1 GHz.
