摘要:
The purpose of this work is to understand the interaction of high energy neutrons with CCDs with the aim of deploying them in flight experiments to gather a database of atmospheric neutron interaction events in silicon cells. The new results in this paper include 1) early-time multilevel RTS signals from dark current spikes, which have never been resolved before and 2) improved resolution of the frequency distributions of event intensity and comparison with results from a radiation transport code. This work adds to the state-of-the-art by providing a novel perspective on the formation and evolution (annealing) of displacement damage complexes in silicon and by demonstrating that CCDs can provide an attractive combination of spatial and intensity resolution for the interaction events of neutrons and other particles within silicon cells.
