Event Recording in Neutron Detection

While neutron sources provide significantly less individual counts than photon sources, neutron experiments will still benefit dramatically from this initiative. With the move to event recording every neutron count is kept - for each event 16 bytes (this is advantageous for stroboscopic experiments and those where sample conditions are continuously changed). Because the count rates scale with the beam intensities, of around 106 ns-1 for a monochromatic (approx. 50 GB/day) or much higher again for a white beam experiment, it is foreseen that fast data rate methods can be applied to the newest instrumentation such as NEAT2 (HZB) or on ESS and SNS. The proposed "DiffractomEter for Nonequilibrium States of condensed matter" DENS at the SNS will produce peak count rates of some 40 Tbytes/h
