  1. The AGATA Project International experimental facility for the investigation of nuclear structure, nuclear astrophysics and fundamental interactions • 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 < 50 keV to > 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.

  3. AGATA Facility AGATA is intended to be an independent, movable Research Infrastructure to be coupled to stable and exotic ion beam accelerators in European host laboratories Accepted Host Laboratories for the Demonstrator Phase 2008-2011: LNL Legnaro GANIL Caen GSI Darmstadt ILL Grenoble Interested Host Laboratories for the AGATA array: FAIR / GSI Darmstadt SPIRAL 2 / GANIL Caen SPES / LNL Legnaro REX-ISOLDE / CERN Geneve JYFL Jyväskylä ILL Grenoble ....

  4. AGATA R&D Phase Prototyping, testing, commissioning... • Develop 36 fold segmented encapsulated detector of right shape • Develop cryostat for groups (“clusters”) of these detectors • Develop digital electronics (700 channels) • Finalise signal algorithms for energy, position and time • Develop tracking algorithms • Build demonstration unit to prove tracking in real situations • Write technical proposal for full array

  9. Köln in-beam test 2005 REACTION CHANNEL: (d,p) PSASegDet 1382 keV

  10. AGATA Design and Construction Infrastructure in time... • 180 geometry defined • Conceptual design of 180 array done • Details of HV, LN2 control etc. agreed, GSI test done • Design of AGATA demonstrator for LNL in final stage • Flanges manufacturing started • Assembly in LNL in autumn 2007

  11. Status of the AGATA Project What remains to be done • Next steps • Build up triple detector (s) • Ge detector characterisation • Pulse-shape analysis algorithms optimised • Gamma-ray tracking algorithms optimised • Electronics and DAQ prototypes and production • Demonstrator ready by 2008 • First physics campaign at Legnaro in late 2008 • Further campaigns at GANIL, GSI, (ILL)

  12. AGATA Project Evolution How to proceed • Demonstrator ready in 2008 • Next phases discussed in 2005-2007 • New LoI for construction phase 2005 • First funding bids for production in D and I successful • New MoU in preparation (required by D in 2007 to release funds) • New organisational structure • Start construction in 2008, 1 in possible in 2011 • Rate of construction depends on production capability • Physics exploitation in stages, AGATA facility development

  15. AGATA Funding AGATA is a moving Research Infrastructure developed, built and operated by a truly European research collaboration • 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 A dedicated funding scheme supporting medium scale European projects is needed • 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
