Project details

Project astract The project aims at the development and application of a very powerful new technology in which there is a rapidly growing interest from many different areas of the physics community. This technology is currently not produced, either commercially or otherwise, outside of Russia. These semiconductor photon detectors have properties that give them features approaching those of a traditional PMT but with several additional advantages. This project involves two applications: PET (Positron Emission Tomography) in nuclear medicine and TOF (Time of Flight) in astrophysics, to demonstrate the foreseen benefits of this detector. However, it is envisaged that such a detector could have far reaching benefits not limited to these fields but applicable to virtually every field where photo-detection is required. They are particularly suited to application to the readout of scintillators for radiation and particle detection. In general, scintillators, especially the faster ones, tend to emit in the blue /green region of the spectrum where the current SiPM devices have low efficiency. New technological processes will be implemented in order to surmount the challenges of developing the SiPM with improved sensitivity in the blue spectral region and forming it into matrices for applications calling for position resolution.<br/><br/>

DISI Sub-project details

Project astract The activity to be carried out at Trento is concerned with the development and optimization of the fabrication technology, with emphasis on the microcell optical isolation. To this purpose, the properties of deep trenches obtained by wer or dry etching and filled by metal will be comparatively evaluated by means of electrical and electro-optical tests. Then, an optimal layout for the microcell will be studied to improve the area efficiency.
