Germanium detectors have reached an unprecedented level of sophistication and they are still the best solution for high resolution gamma spectroscopy. On the other side, they are expensive, need specific support infrastructures also during normal operation and from time to time require expensive repairs. Recently advances in electronics and cryogenic cooling systems could help to reduce the standard operational costs of Ge detectors but technological R&D is still needed to produce cheaper and most reliable detectors.The Legnaro National Labs (LNL) has a long tradition in nuclear spectroscopy studies. Many gamma-ray arrays have been operated at LNL in the last 30 years since the installation of MIPAD in 1987 [1]. In 1991 we have designed and installed GASP, a gamma array composed of 40 Hyper Pure Ge detectors (HPGe), that have been run since 1992 [2] till 2012. During the same period we have installed other gamma arrays at LNL in collaboration with institutes of all Europe, like EUROBALL [3, 4, 5] in 1997-1998, CLARA [6] from 2004 to 2008 and recently, after a short demonstration phase, we have performed the first physics campaign of AGATA in the period 2009-2011 [7, 8]. The experience accumulated in these years spurred us to start a multidisciplinary research program for developing new technologies for the fabrication of highly segmented HPGe detectors, useful for gamma tracking.
