To improve the sensibility of many of our experiments we need to reduce the background. For this purpose we are developing new  techniques.

The Beta Environmental Fine Structure (BEFS) is a modulation of the electron emission probability due to the atomic and molecular surrounding of the decaying nucleus: it is explained by the wave structure of the electron in analogy with EXAFS. It has been suggested that this sensitivity of the beta decay to the atomic environment could be exploited for analytical purposes. 

Low temperature microcalorimeters can be designed for high energy X-ray spectroscopy. Such detectors may have an impact in many frontier fields like have astrophysics, material analysis, nuclear safety and diagnostic, archaeometry, and quantum communication.
