WP2: Interaction position determination using pulse shape analysis Manchester, Liverpool, Surrey Tasks:  Detector Characterisation C001 detector scan  MGS 3D Simulation code comparison with expt. Work in progress  Pulse Shape Analysis (PSA) development Work has started

WP 2 report General Comments: S. Moon and A. Robinson started as PDRAs PSA team meetings AGATA week in Cologne (30 March) Legnaro (21-22 May 09) Bi-weekly telephone meetings

Detector Characterisation Offset of the horizontal segmentation line in rings 2 and 3, due to the electron and hole drift profile being influenced by the fast/slow axis orientations. The scan of detector C001 revealed a 12° offset toward segment B from that specified by the AGATA collaboration. Implication need to characterise to determine true axis orientation

Detector Characterisation Singles scan C001 Output: 2 IEEE TNS papers, 1 NIM paper, 2 APS conference proceedings.

Detector Characterisation Development of improved performance scanning methodology. Full scan presently 2 months The Pulse Shape Comparison (PSC) Scan method [F.C.L. Crespi, NIM A, April 08] Chi-squared minimisation of pulses shapes recorded from two collimated beams injected at 90 degrees to each other in sequential measurements. This process requires only a singles scan and therefore would in principle allow a detector to be characterised in a fraction of the time.

Detector Characterisation Coincidence scan C001 delayed due to cooling problem requiring FET replacements. Detector now being scanned (WP1)

MGS 3D Simulation code comparison Basis data set optimised for symmetric detectors.

MGS 3D Simulation code comparison Majority of difference can be accounted for by differential cross-talk correction.

MGS 3D Simulation code comparison
