Characterization of a flux-driven Josephson parametric amplifier with near quantum-limited added noise for axion search experiments

no code implementations21 Jan 2021 Çağlar Kutlu, Arjan F. van Loo, Sergey V. Uchaikin, Andrei N. Matlashov, Doyu Lee, Seonjeong Oh, Jinsu Kim, Woohyun Chung, Yasunobu Nakamura, Yannis K. Semertzidis

By operating the JPA at a gain of 19 dB and cascading it with two cryogenic amplifiers operating at 4 K, noise temperatures as low as 120 mK were achieved for the whole signal detection chain.
