Description

The paper introduces a portable digital spectroscopy with LaBr3 (Ce) detector and 4096 channel transformation gain implemented by embedded FPGA. Among which nuclear pulse signal is processed by digital signal processing method such as digital trapezoidal filter and the spectroscopy is processed by NIOSII soft-core such as digital spectroscopy stabilization, nuclide identification and etc. The test shows that its spectroscopy resolution is less than 3% and maximum pulse passing is 200 kcps.
