Development of 3D Detectors at FBK-irst

Abstract

We report on the development of 3D detectors at Fondazione Bruno Kessler-irst in the framework of the CERN RD-50 Collaboration. Technological and design aspects dealing with the 3D Single Type Column detectors are reviewed, and selected results from the electrical and functional characterization of prototypes are reported and discussed. A new detector concept, namely 3D Double-side Double Type Column detectors, allowing for significant performance enhancement while maintaining a reasonable process complexity, is finally addressed.
