X-ray technological irradiation for TID studies on silicon sensor and electronic devices in a medical facility

Abstract

Technological tests of Total Ionizing Dose effects are required not only for silicon particle sensors developed in high energy physics experiments, but also for electronic devices and semiconductor elements used in commercial, automotive and space applications. Using x-ray irradiators, these technological tests and studies can be performed not only in facilities explicitly built for this mission, but also in medical or biological research facilities when some minima requirements are satisfied. Generally this irradiation can be performed without interfering with the medical and biological activities of the facility. In this article will be described the minimum instrumentation required for this type of studies and will be given a detailed description of the preparation and realization of a SiPM x-ray irradiation campaign for TID characterization realized in the Italian TIFPA-INFN Trento Center Laboratory in May 2021, using instruments originally realized for medical and biological irradiation.
