Abstract
We report on the development of Mo/Au based transition edge sensors (TESs) aimed at soft X-ray detection. TESs of different sizes with T c ∼ 100 mK and very narrow transitions have been fabricated. Dark characterization based on I–V , complex impedance, and noise measurements has allowed us to obtain their basic functional parameters at different bath temperatures and operating points. Electrodeposited Bi films, to be used as X-ray absorbers, have been developed and characterized.
