Digital Pulse Shape Acquisition From BaF2: Preliminary Results

The use of NE102A-BaF2 phoswich detector drastically improves the particle identification with respect to BaF2 crystals. To better exploit the possibility of light ion discrimination we plan to apply digital signal processing to the signals on-beam collected with NE102A-BaF2 phoswich. In this contribution we present the preliminary results obtained for the natural background of BaF2 and for the heavy ion charge identification (up to Z = 50) and light particle mass identification using digital pulse shape acquisition and a 12-bit, 2 Gsample/s sampling analog to digital converter.
