Presentation Transcript

  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.

  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
