In this work we present the first results of a detector characterization technique named Pulse Shape Comparison Scan (PSCS), applied to a large volume segmented HPGe detector of the AGATA array. The experimental data were collected with the Liverpool University scanning system. Processing two sets of singles scan data acquired with a 137Cs (662 keV) gamma collimated source (with the collimation lines...
Gamma ray tracking arrays like AGATA and GRETA are composed of position sensitive segmented HPGe detectors. In fact the gamma interaction localization with a precision of at least 5 mm is an important step to efficiently perform the tracking. This position information is obtained with the combined use of detector electrode segmentation and Pulse Shape Analysis (PSA). In this work a generalized version...
The 16-channel module (BaFPro) that we have originally developed for processing signals of Barium Fluoride scintillators has been recently adopted to made a pulse shape analysis with signals of Lanthanum Bromide scintillators. Our idea is to use the precision of the fast analog stretcher circuit present in the BaFPro module, to capture in precise way the amplitude peak of the LaBr3 signals. Since...
The position sensitivity of two large volume (1?? ?? 1?? and 3?? ?? 3??) LaBr3:Ce crystals has been measured using collimated beams of 662 keV ??-rays. The crystals have been coupled to a Position Sensitive Photo Multiplier Tube (PSPMT) and/or shielded phototube. The results indicate that, in the case of 662 keV ?? -rays, both crystals should allow identification of the the position of the ??-ray...
