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.

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

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

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
