The AGATA Project First 4pi -ray spectrometer built completely from Germanium detectors. Based on the novel technique of gamma-ray tracking. Measures radiation in a very large energy range, with the largest possible efficiency and with a very good spectral response. Several orders of magnitude more powerful than any current and near-future –ray spectrometer in the world. Key parameters are (i) an energy range 10 MeV, (ii) a photo-peak efficiency of about 50% at 1 MeV, (iii) a position resolution of < 5 mm and (vi) a trigger rate of up to 1 MHz.

Too large for funding within national nuclear structure schemes Too small for CNI funding in FP7 based on ESFRI criteria Moving instrument, therefore no governance by any accelerator facility AGATA Funding NUPNET as "natural" funding agency contact ERANET+ as appropriate funding instrument in FP7 Possibly governance by NuPECC Operation as independent Research Infrastructure eligible for TNA support in FP7 AGATA is a moving Research Infrastructure developed, built and operated by a truly European research collaboration A dedicated funding scheme supporting medium scale European projects is needed
