Proposed asynchronous data collection scheme for stroboscopic neutron imaging on spallation sources for the examination of running engines

Abstract

Even the most powerful steady-state neutron sources do not deliver sufficient flux for neutron imaging with microsecond time resolution. The future pulsed neutron spallation sources will offer a much higher peak flux, but have a low repetition rate that makes sequential data collection and synchronization for repetitive motions rather difficult. This paper proposes an asynchronous data collection scheme for recording movies of fast continuous repetitive motions like running combustion engines.
