19 Andrea Candelori - Irradiation facilities at the INFN National Laboratory of Legnaro – What is SIRAD? SIRAD is the acronym for SIlicon and RADiation. The SIRAD irradiation facility is dedicated: " to investigate radiation effects on silicon detectors, electronic devices and systems in radiation hostile environments ". -Total dose effects as a result of ionization damage. -Bulk effects as a result of displacement damage. -Single event effects as a result of an energetic particle strike. -High energy physics experiments. -Space missions of scientific and commercial satellites.
