Abstract

A 24 segmented HPGe coaxial detector was set up with a digitized data acquisition system (DAQ). The DAQ was composed of a digitizer (5 × 10⁷sampling/s), a Field-Programmable Gate Array (FPGA), and a real time operating system. The Full Width Half Maximum (FWHM), rise time, signal characteristics, and spectra of a ¹³⁷Cs source were evaluated. The data were processed using an in-house developed gamma-ray tracking system.

Keywords: FPGA DAQ; Gamma ray tracking system; Segmented HPGe detector.
