Description
Transition Edge Sensors (TESs) are among the most sensitive sensors for a wide range of radiation energies. They achieve resolving powers above 2000 at keV energies (soft X-rays) with interesting applications in astrophysics and material sciences. They also provide photon counting capabilities in the UVOIR range, which make them also quite interesting in quantum technologies like QKD or fundamental quantum optics experiments.
Our group is developing TESs based on Mo/Au bilayers for the 1-10keV range, achieving <4eV at 6keV (in 250μm wide pixels), with ongoing work to further reduce this figure. We are also optimizing our devices for the UVOIR range, with first proofs of concept already tested in our low temperature laboratory. A general overview and status report of these experimental activities and target applications will be presented in this talk.
