摘要：The Large Hadron Collider (LHC) is a complex radiation environment consisting of several particle types at different energies that affects the electronic equipments. The Radiation Monitoring System, hereafter RadMon, is designed to measure the radiation effects on the electronics in the LHC tunnel and its adjacent shielded areas in order to monitor the radiation levels, anticipate possible device degradation and identify instantaneous failures of the electronic equipments, correlated to their typical Mean Time Between Failure (MTBF) as caused by radiation. The RadMon monitoring aims also to validate the FLUKA Monte-Carlo calculations of the radiation environment as used to predict present and future radiation levels expected for the LHC. For these purposes, the RadMon provides the measurement of the Total Ionizing Dose (TID) in Silicon dioxide by means of Radiation-sensing Field-Effect Transistors (RadFETs), of the Displacement Damage (DD) in Silicon by means of p-i-n diodes, and of the High Energy Hadrons (HEH) and thermal neutrons fluence by counting Single Events Upsets (SEU) in SRAM memory.
