    Abstract

    We demonstrate substantial power gain with a superconducting transition detector. Theoretically we describe the properties of the detector as a power amplifier. In our first experiments power gain of ~25 was reached, in good agreement with the theory. The gain facilitates noise matching of the readout circuit to the detectors in the case of cryogenic time-division multiplexing.
