Pulse shape analysis for the location of the /spl gamma/-interactions in AGATA

A new method to determine the positions and energies of the /spl gamma/-interactions in a segmented HPGe crystal of the AGATA detector is presented. The procedure is able to decompose multi-hit events, even if hits occur in the same segment. We tested the method with simulated signals; noise and the...

Description
Summary:A new method to determine the positions and energies of the /spl gamma/-interactions in a segmented HPGe crystal of the AGATA detector is presented. The procedure is able to decompose multi-hit events, even if hits occur in the same segment. We tested the method with simulated signals; noise and the finite bandwidth of the preamplifier have been considered.
