Abstract
A new Data Acquisition (DAQ) sub-system for gamma-ray diagnostics was developed for Joint European Torus (JET). The system is based on the ATCA platform and is able to sample up to 400 MSPS with 14-bit resolution. This DAQ is used for gamma-ray diagnostics dedicated to the study of fast ions in fusion tokamak plasma experiments. The present work describes the development of pulse processing algorithms used to extract the pulse parameters from the DAQ free running ADC data streams. These algorithms are divided in three main functional blocks, namely, advanced triggering and segmentation, segmentation validation and finally, peak height analysis (PHA) and pile-up rejection (PUR).
