Proof-of-principle of the ultra-narrowband detection scheme at 30 GHz toward weakly interacting slim particle search
A coherent detection scheme was tested for dark photons and axion search with millimeter waves. It was shown that relative bandwidth of 169 μHz can be achieved at the center frequency of 30 GHz by commercial equipment. This is in principle a lock-in amplifier at 30 GHz. With a low noise amplifier, t...
