In the last few years the FAZIA [1] collaboration has been investigating the properties of silicon detectors - in particular the crystal orientation and resistivity non-uniformity - in order to better pin down the detector characteristics that influence their performances for particle identification using Delta E-E and Pulse Shape Analysis (PSA) techniques. In this paper we present the first particle identification results obtained with detectors selected for good resistivity uniformity and using a "non-channeled" configuration. A new digital electronics was also designed for the R&D phase of FAZIA and was tested under beam for the first time. A quantitative procedure to measure the observed performances is applied in order to quantify the particle identification thresholds. Particle identification thresholds of similar to 2.5 AMeV for Z similar to 3-10 have been reached with the studied reaction.

Abstract
In the last few years the FAZIA [1] collaboration has been investigating the properties of silicon detectors - in particular the crystal orientation and resistivity non-uniformity - in order to better pin down the detector characteristics that influence their performances for particle identification using Delta E-E and Pulse Shape Analysis (PSA) techniques. In this paper we present the first particle identification results obtained with detectors selected for good resistivity uniformity and using a "non-channeled" configuration. A new digital electronics was also designed for the R&D phase of FAZIA and was tested under beam for the first time. A quantitative procedure to measure the observed performances is applied in order to quantify the particle identification thresholds. Particle identification thresholds of similar to 2.5 AMeV for Z similar to 3-10 have been reached with the studied reaction.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
