Description

IBS/CAPP has launched CAPP-PACE, direct axion detection experiment aimed at the mass range of 2.45~2.75 GHz. In the present detector setup, we utilize 1K (ultra-low noise temperature) HEMT amplifier which is the world-best available commercial silicon-based low temperature amplifier. However, in order to reach QCD axion sensitivity and speed up the experiment, we are currently examining the possibility of replacing HEMT with SQUID amplifier which could reduce the noise temperature drastically. MSA (Microstrip SQUID Amplifier) is a good option for achieving low noise level. This poster includes new behavior of MSA, gain and noise measurement, and test results under magnetic field. Finalized RF receiver chain of our experiment with MSA will be introduced also.
