SEU Monitoring in Mixed-Field Radiation Environments of Particle Accelerators

Abstract : CERN hosts a large number of electronic devices and equipment, used over its different particle accelerators. In certain areas, they are operating in harsh radiation environments. In order to assure their proper functionality, they undergo several tests in experimental test areas, while specialized monitors constantly record the respective radiation levels. The H4IRRAD experimental test area has been specifically designed to reproduce the radiation field test that is present within the LHC tunnel and shielded areas. It has been used to test our custom SRAM based monitors. The monitors have been exposed to a dose and a high energy hadron fluence of about 76 Gy and 1.3x1011 cm-2 respectively. The results show that the total ionizing dose (TID) effect does not impact the bit cross section of our devices. Moreover the Single Event occurrence is coherent to the beam intensity fluctuations, proving that these devices are appropriate for SEU monitoring under mixed particle fields.
