Superconducting transition detector in power amplification mode: a tool for cryogenic multiplexing
英文摘要：
We demonstrate that substantial power gain can be obtained with superconducting transition detectors. We describe the properties of the detector as a power amplifier theoretically. In our first experiments power gain of 23 was reached in a good agreement with the theory. The gain facilitates noise matching of the readout circuit to the detectors in the case of time division multiplexing.
