7. The AGATA RESEARCH and DEVELOPMENT PHASE 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

8. The First Step: The AGATA Demonstrator Objective of the final R&D phase 2003-2008 1 symmetric triple-cluster 5 asymmetric triple-clusters 36-fold segmented crystals 540 segments 555 digital-channels Eff. 3 – 8 % @ M  = 1 Eff. 2 – 4 % @ M  = 30 Full ACQ with on line PSA and  -ray tracking Test Sites: GANIL, GSI, Jyväskylä, Köln, LNL Cost ~ 7 M €

10. Funding Cost greater than current available funds! Accurate estimates now required for all parts of project

11. Timescale / Project Plan Five year research and development phase of AGATA Start January 2003 End December 2007 Aim to have sufficiently large enough array to test tracking and performance with sources and in beam Timescales are driven by detector and DAQ deliveries. Global timescale estimates: First three symmetric capsules delivered Test individual as 3-unit module by summer 2005 8 asymmetric capsules have been ordered (almost) Deliveries from Nov 2005 to February 2007 Tests of all individual components of DAQ chain by March 2006 Test of complete chain with detector March to June 2006 Production from autumn 2006, delivery early 2007 Source and in beam tests GUI, algorithms PSA, tracking, infrastructure, mechanical design…
