The AGATA Project

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 lt 50 keV
  to gt 10 MeV, (ii) a photo-peak
• efficiency of about 50 at 1 MeV, (iii) a
  position resolution of lt 5 mm and
• (vi) a trigger rate of up to 1 MHz.

AGATA is intended to be an independent, movable
Research Infrastructure to be coupled to stable
and exotic ion beam accelerators in European host
laboratories

AGATA RD 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

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)

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
