Description
I am starting my second year thesis at Paris-Saclay university / CEA, within the ERC G-LEAD project, on the development of innovative electronics for a radiometer aimed at QCD axion dark matter searches.
My thesis focuses on developing a radiometer covering a frequency band from 10 GHz to 40 GHz, corresponding to a axion mass range of $50\mu$eV to $150\mu$eV.
This detector is designed to measure an extremely faint signal, on the order of $10^{-26}$ W/kHz, buried in thermal and electronic noise. It is able of measuring the power frequency spectrum at the output of a horn antenna and a low-noise microwave amplifier chain,both operating in a cryogenic environment.
