Simulation and Data Analysis Working Group Institutionen för Strålningsvetenskap Department of Radiation Sciences Box 535 SE-751 21 Uppsala Sweden WG leader: Johan Nyberg Teams: • Simulation of key experiments • Gamma-ray tracking • Data analysis • Databases AGATA Week, GSI, 21 -25 February 2005 Johan Nyberg

Plan for setting up a ”complete simulation chain” (E. Farnea) ······ ·· · Event generation Data Analysis Detector response Packing and smearing of simulated data * · · · · Pulse shape generation Electronics Response Function g-ray tracking Pulse Shape Analysis to decompose recorded waves

Simulation of key experiments Team leader: Enrico Farnea http: //agata. pd. infn. it/info. html Some ongoing tasks and things to do: • Background suppression • Influence of ancillary detectors • Effect of recoil velocity • Improve the generation of realistic events • Include more ancillary detectors in the simulation code • Define an interface with the pulse-shape calculations • Web discussion was recently started concerning simulations of key experiments • . . . AGATA Week, GSI, 21 -25 February 2005 Johan Nyberg

Gamma-ray tracking Team leader: Araceli Lopez-Martens http: //www-csnsm. in 2 p 3. fr/groupes/strucnuc/trackteam. html Existing algorithms: • Clusterization + forward tracking • Back tracking • Clusterization + probabilistic method • 1 st hit identification with fuzzy Logic + fuzzy cluster AGATA Week, GSI, 21 -25 February 2005 Johan Nyberg

Gamma-ray tracking Examples of ongoing tasks and things to do: • Compared different algorithms with the same simulated data and started combining good features of different algorithms • Checking the influence of neutrons (see talk by J. Ljungvall) • Checking background suppression capacities of algorithms (see talk by E. Farnea) • Use «real» position uncertainties within a detector • Compute «real » effective distances in Ge, not assuming a 4 Ge shell (recently done by E. Farnea and M. Palacz, see talk by M. Palacz) • Interface to data analysis • Optimize tracking codes for speed • Online implementation • . . . AGATA Week, GSI, 21 -25 February 2005 Johan Nyberg

Data analysis (online/offline) Team leader: Olivier Stezowski http: //lyoinfo. in 2 p 3. fr/matnuc/agata/accueil. html Ongoing projects and things to do: • Definition of a common data analysis framework • Gamma. Ware package by O. Stezowski: produce realistic gamma-ray cascades from Rad. Ware level scheme files, which can be used as input to Enrico's GEANT 4 code AGATA Week, GSI, 21 -25 February 2005 Johan Nyberg

Databases Team leader: Karl Hauschild Team formed Jan 2005 Databases for AGATA: • Scanned detector data (wave forms, etc. ) • Calculated pulse shapes • Detector parameters • . . AGATA Week, GSI, 21 -25 February 2005 Johan Nyberg
