Analysis of a microwave cavity detector coupled to a noisy amplifier
Description
In a class of detectors for light pseudoscalar particles, a microwave cavity traps photons produced by the interaction of the particles with a strong magnetic field. The cavity strongly influences the signal and noise properties of the amplifier coupled to its output. We present the theory of a noisy amplifier coupled to a microwave cavity, along with experimental data for a cryogenic GaAsFET amplifier. The signal-to-noise ratio of the cavity-amplifier system is determined, and applications to the measurement of amplifier parameters are discussed. (orig.)
