Abstract :
An 8 Mbit 90-nm memory is proposed as a new high energy hadron fluence sensor. The obtained cross sections for protons (30 MeV up to 480 MeV) and thermal neutrons as well as their dependency on the TID together with the control circuitry is presented. Burst events were recorded during irradiation and an analysis on the causes has been performed proposing an algorithm to mitigate and correct the burst multiple events. Finally, the effects of the energy dependency on the measurements in the LHC mixed radiation field are discussed.
